Influence of filler metal on microstructure and properties of titanium/copper weld joint by GTAW weldments

From steel designed to work under pressure and exposed to high temperature apart from the good weldability, good mechanical properties are required. The guidelines set by the regulations require post welding heat treatment above 35mm thick. An important factor affecting the microstructure and properties of the joint made of thick-walled elements is heat treatment after welding. All welding operations must be properly planned before performing welding work. Welding procedure specification (WPS) is a document describing these operations, it is essential for proper determining of basics in planning welding operations and quality control in welding. The purpose of this paper is to compare the properties of joints made by 121 welding method in combination with and without post welding heat treatment.

2519A/7A52 aluminum alloys were welded by using ER4043 and ER2319 welding wires with the method of MIG. The mechanical properties, microstructures as well as fracture of welded joints were studied. The results show that the welding wire of ER2319 is favorable for grain refinement of welding structures, and the strength and elongation of the joint are better than that welded by ER4043 welding wire. While for the use of ER4043, the strength and ductility of joint decline due to the generation of Si-rich brittle phase, and the fracture of weldment is mostly brittle type.
