ABIBLOG USA: ABICOR BINZEL's Welding Blog

Are you looking to continue advancing your welding process? You've completed the first step by adding robots to your operation, but now you're looking to improve safety among your team. Step two is setting up a robotic fume extraction system in your plant to improve air quality. The xFUME^® ROBO by ABICOR BINZEL USA and CA is the most effective and economical way to control welding smoke emissions with fume source capture.

There are two physical elements of weld wire to be aware of in a robotic welding application. The first is the cast, which is the natural curvature of the wire. The second is the helix, which is the natural winding geometry of the wire's radial shape. 

ABICOR BINZEL USA is now offering full turn-key solutions to fume extraction welding in both automated, robotic applications and manual applications.

Micro-arcing in a welding process are small arcs, usually not visible, that happen within the contact tip or wire liner. Instead of making a positive contact all the way through the tip, or at least always on the tip at some point, your wire is making inconsistent contact to the contact tip. This compromises current transfer and causes the wire to micro-arc inside the contact tip.

Porosity is the bane of existence in robotic welding.

It happens. You don’t know where it comes from all the time, or how it’s happening, and you spend days or even weeks troubleshooting to figure it out.

We’ve all been there.

A burnback in welding is when your wire burns back and sticks itself to your contact tip. There are several reasons this can happen. The most primary causes of burnbacks in a robotic application include:

Galvanized has become increasingly popular in the automotive manufacturing space as a corrosion resistant coating on steels. Mainly, it's put on there in a hot dip fashion where you're actually dipping the material in molten zinc and coating it that way. There's electro plating and galvanneal plating also. 

When I used to teach robotic welding misconceptions, I used to try to clear up to people:

Spatter is weld wire.

Many manufacturing engineers are under the impression that spatter is the puddle exploding. That is true to a point, but where the misconception often comes in play is the thinking that the source of spatter is the base metal, which it is not. Really, spatter comes from the filter metal.

When you are evaluating a new robot welding torch, the ramifications of the testing is huge. Normally for large manufacturing companies, this is putting a solutions on the production for years with a high equipment investment. This makes the need to get great data to use to evaluate the right solution critical.

The robotic fume extraction landscape has featured few lean, advanced, and cost-effective solutions for manufacturers. While fume extraction for manual welding has experienced a significant spike in new solutions entering the market – from high-vacuum systems to multi-gun units, to countless new fume extraction gun concepts – robotics has remained ignored and mostly unchanged with minimal innovation to speak of.
