ABIBLOG: ABICOR BINZEL's Welding Blog

The valve on the gas cylinder is turned open as far as possible so that gas flows sufficiently and a safe shielding gas coverage is ensured. Finally, the weld seam should be of good quality and besides ... gas is always there. In this way, day after day, litre after litre of shielding gas flows out of the gas cylinder into the working area, and thus into the environment, completely unnecessarily. At first glance, the gas manufacturer may be pleased with the high gas consumption of the customers, whereas the bank account of the producing company and the environment are not. However, it is so easy to reduce gas consumption through the appropriate gas setting in gas-shielded welding – and this applies to robot welding as well as to manual welding. Yes, that' s right: manual welders can also have the exact amount of shielding gas supplied automatically. And they can do this completely without a pressure regulator for shielding gas.

Practical tips about all you need to know about gas nozzles for MIG/MAG torches

The MIG/MAG welding process is very demanding and both man and material are pushed to their limits? – often even beyond. Therefore, it is all the more important to work with good tools, especially the welding torch with its wear parts. These parts are very close to the process and have to withstand heat and weld spatter for as long as possible. Especially the gas nozzle, which, in addition to its actual task, is often misused as a hammer.

When welding aluminum, as with all other weldable metals and metal alloys, emissions arise in the form of combustion and evaporation residues.

Which protective measures are suitable here and is aluminum welding toxic?

When it comes to welding fume extraction, a couple of questions are frequently asked. Often it is about the performance, weight or handling of fume extraction torches, but also the service life of welding fume filters in extraction devices or the correct volume flow control are recurring topics.

Since welding fumes are toxic and the extraction of welding fumes should be mandatory to protect employees, we answer the most frequently asked questions about welding fume extraction and clear up common prejudices and concerns so that you can find the perfect solution for you and your welders.

The fact that the welder is close to the welding process and would therefore be completely exposed to the dangerous gases in the welding fumes without a fume extraction system is no surprise. But how is the situation when using a robot for welding? Do similar precautions need to be implemented as with manual welding? Just as with manual welding, the dangers of welding fumes should not be underestimated.

Gas-shielded metal arc welding – also known as GMAW welding or MIG/MAG welding – is by far the most applied and most common welding process in welding technology. When searching for the cause of weld spatter, this process literally hits the bull's eye. Whereas with TIG welding and plasma welding almost no weld spatter occurs, spatter formation in GMAW welding can never be completely prevented. The question may arise why not use TIG or plasma welding in general if welding spatter should be avoided as much as possible. To get the answer it is necessary to take a closer look at the process of MIG/MAG welding and the cause of weld spatter.

Flammable vs. non-flammable anti-spatter sprays

Wherever welding takes place, weld spatter also occurs. During MIG welding and MAG welding, spatter formation is particularly high. Although it is possible to reduce the formation of weld spatter in these processes through process optimisation, it can never be avoided completely. Since weld spatter partially sticks, a good preparation is required, because it can be found almost everywhere: on and in the front end of the torch including the gas nozzle, on the contact tip and contact tip holder, on the workpiece as well as on the clamping element, if used. However, by applying a good sprayable anti-splatter agent, which is suitable for all areas, the majority of the welding spatter can be kept away or easily removed.

Extracting harmful welding fumes should be standard in every manufacturing company for health reasons. Many rely on large extraction systems for extraction, which completely exchange all of the hall air within a very short time. More efficient and far cheaper than such large air filtration systems are extraction devices where appropriate fume extraction torches can be connected for source capture. With the fume extraction torches RAB GRIP and RAB GRIP HE 2 from ABICOR BINZEL, fume extraction is easy.

Whether it is an anti-spatter spray, a paste or an emulsion: anti-spatter agents for welding are available on the market in many variants - for using on the welding torch, on the work piece or even on both.

They all serve the purpose to avoid time-consuming rework by removing weld spatter from the work piece, to reduce downtimes due to frequent wear part changes, and to ensure that tools used in the welding process, such as clamping devices, always remain fully operational.

What role does it play whether an anti-spatter agent is flammable or non-flammable? Moreover, are all non-flammable anti-spatter agents equally good?

7 practical tips for a neat weld seam

No question: aluminum welding is the premier class of welding. In a previous blog we explained in detail what a manufacturing company should pay attention to when welding aluminum by hand. But what do you do when the quantities are so high that one welder alone can no longer handle them? If hiring an additional welder for aluminum welding is not an option or you simply cannot find a suitable welding specialist? Can you possibly also weld aluminum in industry with a cobot – i. e. a collaborative robot – or is it too difficult to program a cobot to achieve the same results as when welding aluminum manually.

Is automated TIG welding economically viable?

When automating a TIG application, the first question to ask is the same as for any other automation: Is it profitable to use a robotic welding torch or a robotic welding cell?

When you think of the dangers of welding, the usual suspects immediately come to mind: In addition to obvious things like harmful UV radiation during arc welding, sparks and welding spatter, or even hazards from electrical current, there are also the invisible dangers of welding, for example, by inhaling harmful welding fumes.

There are multiple ways to protect the welder from all these hazards: Wearing personal protective equipment (PPE) when welding is considered a matter of course and protects the skin and, above all, the eyes from radiation and injuries caused by welding spatter and flying sparks. Fume extraction torches, ventilated welding helmets or fume extraction systems can filter toxic welding fumes from the air and thus protect the welder's respiratory organs.

But how can welders protect themselves in the long term against damage to their musculoskeletal system? What helps against permanently tense muscles, signs of fatigue and back pain?

An often underestimated aspect of welding is the welding torch itself!

EWR 2 gas management system for welding: saves gas right from the start!

What makes a company a Green Factory? Everything that has to do with sustainability. Using renewable raw materials, grow organically, use of solar energy, save CO₂ ... these are all approaches that can make our world a little better. One or the other can also be implemented in welding technology and fortunately it is becoming increasingly important for companies to do something to protect our environment. The trend is towards becoming a so-called Green Factory. ABICOR BINZEL can support you or your company on the way to the Green Factory. Or expand your status as a Green Factory.

When welding metals, there are a number of emissions which, on the one hand, cause the legally prescribed MAK values (“maximale Arbeitsplatz-Konzentration”: maximum workplace concentration) to rise above the permissible threshold value and, due to toxic and / or disease-causing ingredients, represent a health risk for the personnel in the processing area. This fact obliges companies in the welding industry in particular to ensure effective air filtering and ventilation in the areas concerned. Because not only the welder himself is affected by the harmful emissions, but also the rest of the staff in the production hall, who are exposed to the welding fumes.

In addition to a large number of stationary fume extraction systems, the torch-integrated fume extraction (fume extraction torches) is one of the most effective and mobile methods that can be used. Welding with fume extraction torches is definitely a challenge when it comes to the handling.

So how can you weld correctly with fume extraction torches? What do you need to pay attention to?

The welding robot has been programmed for hours. The straight paths work perfectly, when welding a curve everything is wrong back and forth – what happened? The industrial robot is synchronized, the component is fastened and the weld seam is still set incorrectly – where is the mistake? On the first day, tens of components were perfectly welded, the next day the seam was displaced – how could that happen?

Purchasing a fume extraction unit is the first step in the right direction. To protect the welder and other endangered persons from the dangers of welding fumes for as long as possible, there are a few things to consider, especially when it comes to the fume filters. The fume filter ensures that the hazardous gases in the welding fumes are filtered out and that the working environment is safe for everyone. How exactly does that work?

Why shielding gas offers a huge savings potential

The valve is opened and there it is: the shielding gas for welding. Depending on the requirements of the welding task, the gas pressure and gas quantity are still set with the manometer before starting. Pre-flow time? Rather a little longer. Better safe, than sorry. The same applies to the post-flow time. Whether this lasts a few seconds longer or not does not seem to make much difference. Or maybe it does? The fact is: the shielding gas consumption is usually much too high. With the gas management system EWR 2 you can save money in gas shielded arc welding.

5 essential tips how to sharpen TIG welding electrodes correctly

Excellent-looking weld seams can be conjured up with TIG welding. It is not only the choice of the right tungsten electrode that has an influence on the appearance and quality of the welding result. HOW the TIG welding electrode is sharpened also has an enormous influence on the weld seam. In this blog we would like to show you how to properly sharpen tungsten electrodes so that this essential welding accessory for the TIG torch can unfold its full effect.

What do you actually use to cool your welding torch? Is water from the regular piping system running through the cooling system of your power source or have you filled in coolant? And do you often have to cope with torch failures? If this is the case, the choice of your coolant could provide information about the reason for the frequent torch failures. In fact, water is often used as a coolant during welding. Why this is not a good idea at all, and why it can even cause torch failures, is explained in this blog.

All about the welding accessories TIG welding electrodes

Finely crafted weld seams, clean welded joints, high-quality materials – welcome to the world of TIG welding and tungsten electrodes. Choosing the right tungsten electrode is just as important for TIG welding as the contact tip for MAG welding. The range of TIG welding electrodes on the market is just as colourful as the colour coding that characterizes each individual type of tungsten electrode. In this blog post we would like to give you a good overview of the essential tungsten electrodes to make it easier for you to choose if you want to buy them.

The decision to purchase and use a fume extraction system and a fume extraction torch to capture the health-endangering welding fumes directly at the source is becoming increasingly easier for many people. The awareness of the potentially hazardous gases in welding fumes has cleary spread throughout the industry.

It doesn’t have to be a welding robot!

At some point, the time has come and:

• the manual welder reaches the limits of his physical capacity
• the quantities are too large to meet the desired delivery date
• the topic of automation must be discussed

Automation? Aren’t these robot welding cells which usually take up a lot of space and are really expensive? In order to make their purchase profitable, enough parts have to be processed to operate the system at full capacity. In addition, there is the programming of the welding robot, which requires additional knowledge. Is there no interim solution if an industrial welding robot is still a size too big? Yes, there is: cobot welding.

If you are looking to invest in Fume Extraction equipment but you don't want to use manual Fume Extraction torches because they are too heavy, you're using a Machine/Robotic torch and you're concerned about access issues or you're simply on a tight budget - then here are a few external kits that you can use with your existing setup.

RAS Torch Kits 

The RAS fume extraction option is an economical and ergonomic alternative to integrated fume extraction torches e.g. RAB GRIP.

Anti-spatter spray, anti-spatter liquids, anti-spatter fluid and more

You have to break an egg to make an omelet. Especially with MIG/MAG welding, weld spatter occurs, which can already be heard from afar. With this »crackling and cracking« small metal droplets are created that are hurled from the weld pool or from the hot liquid electrode end to the workpiece surface or land on the weld seam and the torch wear parts. Excessive weld spatter is caused, for example, by an incorrectly set welding current, a non-optimal arc, incorrect polarity or insufficient gas shielding. However weld spatter occurs ... burnt weld spatter has to be removed again. This rework costs time and money. Anyone who welds wants to keep the adhesion of weld spatter as low as possible. And if they do stick, they can easily be removed again. Here we answer the questions that our field staff are asked the most on site.

Fume extraction is part of the basic equipment of every welding workplace. There is a wide range of extraction systems on the market, and the requirements are just as individual. From stationary systems that regularly exchange air in a complete production hall to mobile fume extraction with the absorption of welding fume directly at its point of origin, the so-called source extraction, there are many variants. In a previous blog, we went into more detail about the benefits of the extraction at the source. Today we want to focus on the costs that you will face if you want to buy a fume extraction system.

What you need to know for the use of power contact tube, contact nozzle, contact tube & Co.

The contact tip – also known as contact nozzle or power contact tube – is the smallest but most important wear part on a MIG/MAG torch, and it makes no difference whether it is a hand-held torch, an automatic torch or a robotic welding torch. The contact tip has a very considerable influence on the quality of the MIG/MAG welding process and the service life or machine availability in the welding process.

The beam on the workshop floor seems endless. The back hurts already at the mere thought of having to weld in the same position for the next few hours. Take up position, put on, weld off, put down, slide forward. Unfortunately, it is unavoidable that over time the welding seam is not as good as it was at the beginning. Or maybe it can? Automated welding provides a remedy ... for poor weld seam quality of long, repetitive welding tasks, for welding errors, but also for monotonous and painful joints.

Why cobot welding can be the solution for small and medium-sized companies

Automatically working welding robots as far as the eye can see. The robot arms move sometimes hectically, sometimes silently. There is a hiss, hum, and crackle in the air. You can only recognize a person here and there. Automation clearly dominates. Such a vision is more of a fear image for small and medium-sized companies, because people here seem to be completely in the background, yes, being pushed out of their job. So it seems. A machine like a collaborative robot – a so-called cobot – can support people in their work. The use of cobots in welding can thus become an economical solution for small and medium-sized companies.

What really matters when welding aluminum

Frames of bicycles or motorcycles, trailers for trucks, profiles of rail vehicles, materials in space travel – aluminum is THE material when it comes to reducing weight and still achieving stability. In addition, a beautifully welded aluminum seam is a real eye-catcher.

With the new xFUME series we are eliminating harmful welding fumes.

In any manufacturing location across the world, air quality and fume control is an increasing concern. While the welder himself bears the most burden in weld fume exposure and long term health risks, it’s not limited to just the welding operator. Across the entire shop floor – from the forklift operator to administrative staff and walk the floor, exposure to weld fumes is a second hand smoke experience. Even if it’s not always visible or noxious, it’s there. There isn’t a welding operation today that in some way doesn’t need fume extraction.

What is Plasma Welding?
 
‘Plasma’ is the fourth state of Matter.

Every welding job generates fume or smoke that can be hazardous if inhaled. Whether you're welding mild or stainless steel, there is only one effective solution for maximum health protection....Extraction at source!!

If a technically interested person opens a magazine or a newspaper you cannot avoid reading articles about how the “Internet of Things” will change our daily live in the coming years.

During my years as an Area Sales Manager, there was one question that I regularly got asked from our customers & welders:

"Danny, why am I going through an excessive amount of contact tips, gas nozzles, gas diffusors, tip adaptors & liners?"

The answer may be simple.

ABICOR BINZEL is excited to announce the launch of three new ABIMIG torch models to our manual MIG welding line. Our new ABIMIG AT and ABIMIG A combine the ergonomic and comfortable grip of the existing WT in an air-cooled model.
