Welding process
The most important welding processes at a glance

Overview of welding processes
Various welding processes can be used to establish a permanent and stable join between metals. The best-known methods are MIG/MAG (metal inert gas or metal active gas), TIG (tungsten inert gas), and manual arc welding (MMA).
Modern multiprocess devices are capable of performing all three processes to a high level of quality and therefore cover a particularly wide range of applications.
What other welding processes are available?
Alongside these standard processes, specialized methods such as laser welding and plasma welding are also used. The ideal welding process depends on the material, component, and production process. The weld seam profile is equally important because different profiles are required depending on the geometry and demands of the component.
Weld seam profiles
Welding produces different weld seam profiles, depending on the component geometries and the process used. The most important weld seam profiles are the butt weld, lap joint, fillet weld, and corner weld.
Each weld seam profile has specific advantages and disadvantages in terms of strength, accessibility, distortion, and cost effectiveness. The profile selected depends on the component design, load, and welding process used.
