Welding method and its parameters has an important effect on the formability and mechanical properties of tailor welded blanks(TWBs). In this study gas tungsten arc welding(GTAW) is used to joint aluminum TWBs. Aluminum TWBs consist of 6061 aluminum sheets with different thickness of 1mm and 2mm. Main parameters of GTAW consist of welding current, pressure of shielding gas, welding speed and di...

The purpose of this study was to develop a specialized Friction Stir Welding process for superplastic grade aluminum alloy 5083-SP and titanium alloy 6Al-4V, in thickness of 1.5 to 4 mm, such that the butt welded nugget would have equal superplastic forming (SPF) characteristics as the parent sheet material The concept of using tailored blanks for the SPF process is proposed which will allow th...

Due to the high strength weight ratio and ability form desired shape, AA2017 is extensively used in automobile industry. The join with other aluminum alloys capability respond heat treatment creates opportunities for engineers AA6061 blanks using friction stir welding. Controlling process parameters a challenge optimization of tool pin geometry, axial force, rotational speed, welding tilt angle...

Friction stir welding is a solid-state method that produces joints with superior mechanical and metallurgical properties. However, the negative effects of thermal cycle during dent performance weld joint. Hence, in this research study, joining aluminum tailor welded blanks by friction carried out underwater conditions varying parameters. The tensile tests revealed samples showed better results ...

the use of twb has been developed in automotive industries because of it’s advantages such as reduction in weight, cost and fuel economy of vehicles. the main objective of the peresent work is to study the effects of weld zone, diffrence in surface coating and thickness ratio on the formability of twb composed of aisi 304, spcc and if steel sheets. it was found that the narrow weld zone has lit...
