1. Microstructural Transformations in Dissimilar Welds between Austenitic Stainless Steel and Ferritic Stainless Steel
This research studies the metallurgical transformations taking place the SMAW welding of AISI 316L austenitic stainless steel with AISI 430 ferritic stainless steel. To perform the study were used two different electrodes, AWS E309L austenitic and AWS E2209-16 duplex stainless steels 3.2 mm diameter. The joints were made with a single-pass welding including

2. The effect of voltage on the arc stud welding of microwave sintered Fe+Al powder mixture
The joining of powder metallurgy products is of importance because of high demand in many industrial applications. In this study, the effect of welding voltage on the joint quality has been investigated using discharge arc stud welding, a low heat input welding method, without gas protection to join steel stubs to microwave sintered compacts containing a pow

3. Occurrence of Defects in Laser Beam Welded Al-Cu-Li Sheets with T-Joint Configuration
Abstract: In the aerospace industry, laser beam welding has been considered as one of the most promising routes among the new manufacturing processes. Substitution of riveting by laser beam welding of aircraft structures has contributed to weight and cost savings. Concurrently, new aluminum alloys have been developed with the addition of lithium with better
