stainless steel

Stainless steel does not readily corrode, rust or stain with water as ordinary steel does. Although welding stainless steel may not be as difficult as welding aluminum, the metal does have its specific properties that vary from your more common steels. At optimum welding temperature a rainbow color is produced as shown below. If the weld is too hot (a grey color) The material will lose its anti-corosive properties. It is important the welder uses te correct welding electrode or filler rod when weldiing stainless steel.
