چکیده
The welding of non-heat treatable aluminum alloy AA5052-H34 was performed using pressure-controlled joule heat forge method. dislocation density the work hardened decreases at high temperatures, and it is difficult to suppress affected softening zone during welding. In addition, since alloys have a thermal conductivity, transfer likely occur, control temperature. Therefore, in this study, by optimizing specimen shape compression rate, formation unwelded defects effectively suppressed low temperature rapid process. Consequently, sound joint with 100% efficiency successfully obtained without HAZ.

Friction Stir Welding is one of the solid-state processes and today it has been used to join different types of materials. Friction stir welding does not have many problems and limitations due to melting and solidification of weld metal and by controlling its variables, the microstructure and desired mechanical properties can be achieved at the joint. Recently, in most industrial areas, due t...

Dissimilar metals friction welding of austenitic–martensitic stainless steels is commonly used in order to manufacture engine valves in the automobile industry. In this study, X53CrMnNiN219 (austenitic stainless steel) and X45CrSi93 (martensitic stainless steel) valve steel rods were welded by friction welding process. The welded joint was then heat treated at 760 0C for 60 min. Mechanical prop...
