Effect of Ternary Fluxes on Depth of Penetration in A-TIG Welding of AISI 409 Ferritic Stainless Steel
Abstract TIG welding is a preferred process for producing quality weld joints. However, because of its characteristic shallow depth of penetration, productivity achieved by this process is low. Depth of penetration of conventional TIG welding can be ...
