The quality of a weld seam depends on many factors, above all good tools. Welding torches from quality manufacturers are nowadays already technically very highly developed. With new developments, it is often just the little things that make a torch even better. A high-speed camera used in the ARCLab research and development laboratory at ABICOR BINZEL provides important insights for optimisation approaches.
If images from this high-speed camera, such as the melting drops of the filler material, are combined with electrical parameters, information on process stability is obtained. If you combine the camera with a visualisation of the gas flow – and carry out a so-called Schlieren measurement – you can see how well the protective gas flows out of the gas nozzle.

The welding torch development department receives important data from these test results and can recognise whether the current approach is correct or whether further parameters need to be adjusted. Please also have a look at this video:
Always the ideal amount of protective gas
In everyday work, a little more gas is often supplied than is necessary for the welding task. In the past, this was not something to worry too much about, because there was always enough shielding gas available. Nowadays things look different. Shielding gas should not flow out unused. With a clever gas management system like the ERW 2 or the EWR 2 Net, the ideal amount of shielding gas is always available – for manual welding as well as for robot welding. With such a device integrated into the welding process, there is no sudden release of gas during the initial gas burst and there is no longer any danger of not having enough shielding gas coverage due to deposits or leaks in the gas line. Some of the potential gas savings with EWR 2 are incredible. Feel free to determine your savings potential with this simple calculator. You will be amazed at what is possible for you.
