Why is stainless steel used in resistance welding?
The low thermal and electrical conductivity of austenitic stainless steel is generally helpful in welding. Less welding heat is required to make a weld because the heat is not conducted away from a joint as rapidly as in carbon steel. In resistance welding, lower current can be used because resistivity is higher.See all results for this questionWhat makes duplex steel more resistant to SCC?SCC is due to the combined influence of a corrosive environment and stress (applied or residual). Standard austenitic grades are highly sensitive to SCC in chloride-containing environments, especially above 50°C. The combination of ferrite and austenite makes duplex steels significantly more resistant to SCC. d- Intergranular corrosionSee all results for this questionWhat do you need to know about submerged arc welding?Submerged Arc Welding (SAW) process involves formation of an arc between a continuously fed bare wire electrode and the work-piece. The process uses a flux to generate protective gases and slag, and to add alloying elements to the weld pool. A shielding gas is not required.See all results for this question
