During welding, temperatures above 300 °C are reached, and as a consequence, a thermal oxide (heat tint) is formed on the surface near to the weld. This heat tinted zone has a lower corrosion resistance compared to the parent metal and it is more susceptible to local corrosion attack. For instance, pitting and crevice corrosion may be initiated in the tinted zone. Heat tint is formed by reaction of stainless steels with oxygen in the shielding gas, at high temperatures. In practical applications argon with the addition of H2 are mostly used as shielding gas (formier gas). The aim of this paper is to provide a deeper insight into the various aspects related to the occurrence of the heat tint near the welded joints of stainless steels. A survey of methods and procedures to prevent and remove heat tint is presented. |
