Outstanding resistance to localized corrosion and excellent resistance to stress corrosion cracking. Stainless steel is often used because it is very resistant to both rust and corrosion, thanks to the high levels of chromium contained in it. An Article on Corrosion in Weldments was published (7) in the Issue 32 of Practical Welding Letter for April 2006. Stress Corrosion Cracking Locations. Learn how to weld austenitic stainless steels by all processes. If you want the most professional look and corrosion protection do not buff your. Detected defects, and stress-corrosion defects are located predominantly in the lowest part of pipeline circumfer- ence; they tend to be located along longitudinal weld seams. If the flow lines are welded, the operator should be certain that the weldments are at least as corrosion resistant (and where H2S is present, as cracking resistant) as the pipe body. I have spent many years welding stainless steel for marine environments. REACTORS: All weldments; circumferential welds by which nozzles are attached; radius of dished head; external jackets especially half-pipe coils. Best alloy to use as universal weld filler metal to resist corrosion of weldments. Being able to weld stainless steel is a great skill for any welder to have because not only does it make a welder very valuable, but some jobs are designed just for welders capable of welding stainless steel. It isn't the easiest metal to weld.
