On stainless steel for example any color in the weld or haz shows that an oxide layer has formed which can affect corrosion resistance.
The darker the color is the thicker the oxidization.
Welding of stainless steels 1 0 introduction stainless steels are defined as iron base alloys which contain at least 10 5 chromium.
Choosing one of the six commonly available tungsten electrodes is a crucial first step in successful gas tungsten arc welding gtaw.
The end preparations are balled pointed and truncated.
