The tempering colors are caused by the high heat development during stainless steel welding. Tarnish colors (tempering colors) are caused by the simultaneous action of heat and oxygen. These show up as colored surfaces in the area of the stainless steel weld seam.
You can safely and environmentally friendly remove these temper colors around the stainless steel weld. Simply use our TIG-MAX XT®, TIG-MAX® and TIG Brush® picklers.
In contrast, when cleaning the welds by grinding the surface and applying an aggressive pickling paste, the surface of the stainless steel is permanently destroyed. The pickling paste applied in this process, which is rinsed off after a contact time, is extremely toxic and harmful to the environment!
