TIG welding without tempering colours: Using all the possibilities

In the household appliance industry, high-grade steel (high-alloyed chrome-nickel steels) is mostly utilised as a design element in the visible area. In this respect, minute scratches, dents and discolour ations are often already a reason to reject parts. As a result of the design, welds are ever more frequently located in the visible area and entail the risk of tempering colours. However, the subsequent machining of the welds is often too time-consuming and too expensive, particularly in the case of larger components, and leads to non-uniform surfaces in most cases. Therefore, it is indispensable to avoid tempering colours here.
