From a scientific point of view: How to make welding easier

What exactly is the strain on a welding specialist? How can this physical strain be reduced and is it even possible to prove it? As a professor of joining technology, I get to the bottom of these questions scientifically.

1. What is the strain on a welder?

First of all the weight of a manual welding torch, which can be less or more strenuous depending on the welding position. Welding in flat position is therefore less stressful than overhead welding in a standing position. If the welder has to bend forward when welding, completely different forces act on the musculoskeletal system.

2. What can be done to reduce this strain for manual welding?

The first measure is to reduce the weight of the welding torch, which is achieved by using lightweight metal components in the cable assembly. But the ergonomics of a welding torch are also crucial: a handle size that suits the user supports grip strength. A well-balanced welding torch does not impose additional forces on the wrist, which lead to fatigue and strain.

3. How can the strain during manual welding be determined?

Electromyography is a very good method for demonstrating physical exertion. For this purpose, electrodes are attached to all body regions exposed to strain during welding, such as forearms, upper arms, knuckles, shoulders and back, and their signals are recorded and evaluated. This data clearly visualises the strain on the individual body regions.

The studies already carried out by ABICOR BINZEL with the Justus-Liebig-University in Gießen have shown very clearly: Welding with lightweight, ergonomic welding torches puts less strain on the welders. ABICOR BINZEL has offered lightweight and ergonomically adapted welding torches on the market for a long time, which have been scientifically proven to reduce the physical strain on welders. And the best thing about it is: The users are enthusiastic!
