摘要：

Metallic welding coating of corrosion-resistant steel and special alloys is a reasonable economic alternative compared to solid components manufacture from these alloys. The objective of this work was to evaluate surface residual stress in stainless steel AWS308-L T-1 coatings applied by Flux-Cored Arc Welding and Submerged Arc Welding on ASTM A36 steel plates. Residual stress measurements were performed by a portable X -ray diffractometer on coating surfaces. The main results showed that residual stress on coating surface presented compressive nature, also residual stress magnitude versus welding energy was not a linear function, and thus it is noticeable potential level influence on corrosion resistance of coatings.
