Summary: For precision applications, one of the methods to reduce distortion due to welding of stainless steel is the use of penetration enhancing compounds. Historically, significant effort has been taken to quantify the heat input, penetration, and weld metal properties resulting from penetration enhanced gas tungsten arc welding. However, this is one of the first accounts to show the significant reduction in distortion that can be attained through the use of penetration enhancing compounds. Experimental results as well as FEA predict significant reduction in distortion from penetration enhanced gas tungsten arc welding as compared to the conventional gas tungsten arc welding.
