Abstract
This paper presents the corrective measures to avoid crack formation in ferritic stainless steel grade 409L after TIG welding. Amongst the numerous welding methods, TIG welding is the most commonly used method for stainless steel welding process. Generally cracks are seen after certain duration of time at weld line or near a weld zone. This paper also deals with complete analysis of TIG welding, respective parameters, quality of weld, causes of crack formation and suggests remedial measures to reduce percentage of rejection due to cracks and improves quality of weld. It also reduce considerable power requirement and achieves economical production. Index terms - TIG, Hydrogen Embrittlement, Nascent Hydrogen, Stress Corrosive Cracking.
