Avoid Spatter and Rework with Premium Anti-Spatter Solution
CS Unitec Inc., Dynabrade, Inc., ESCO Tool, Fronius USA LLC, Gema USA Inc., Madison Chemical, Saint-Gobain Abrasives, Osborn, NovoFlex, Rex-Cut Abrasives, TRUMPF, WALTER Surface Technologies
The E-WELD 4™ is available in aerosol, liquid spray bottle, bulk and with the unique Air Force System to help you optimize your welding productivity.

The hassles, costs, and delays caused by spatter are well known in the metalworking industry. The main causes of these imperfections are typically poor surface preparation and incorrect equipment settings.

The adherence of spatter to a base material is a time-consuming challenge frequently faced by welders. It is visually undesirable and can lead to part assembly interference.

There are different solutions to preventing weld spatter from building up and causing quality and productivity issues.

Manual cleaning with hammers and chisels for example is a labor-intensive task that causes the most delays and disruptions while highly contributing to operator fatigue.

Grinding or sanding can be an effective method to removing spatter, but they can just as easily damage the surface of your metal and disrupt production. This damage is often costly and time consuming, having to rework the piece and restore it to its desired finish.

There’s a faster, easier, and safer process.

The WALTER Surface Technologies’ (Windsor, CT) E-WELD 4™ is a premium anti-spatter solution meant to protect your workpieces and is guaranteed not to cause weld porosity. It eliminates the need for this costly rework by forming a barrier on the material minimizing the adherence of spatter to the base metal making it easy to remove after welding. The non-toxic, non-flammable and silicone-free formula does not contaminate the weld pool, and also retracts in the presence of heat, leaving the welding area liquid free. This contributes to the reduction of weld porosity or weld cracks.

It’s also an excellent corrosion resistance which makes it ideal for ferrous alloys and corrosion sensitive parts.
