Dissimilar metals joints between aluminum and zinc-coated steel were joined by CMT machine with ER4043 filler metal. The microstructure and mechanical properties of the joints obtained with different heat input were analyzed. The results showed that the thickness of interfacial intermetallic compound was determined by the welding heat input. Tensile specimens were broken in HAZ of aluminum base metal and the tensile strength of the joint can reach 122.3MPa.

Joining of aluminium alloys to steels has been extensively studied, especially in the automotive sector. However, aluminium alloys are known to be difficult to join with steels when methods involving fusion welding are used because of hot cracking problem. Hence, a high strength joint between these dissimilar metals would be of benefit especially in reducing the weight of products. In this work the torch brazing method was applied to join AR500 steel with AA7075 aluminium alloy using Al-Si-Zn base filler metal at various flame times. The effect of the brazing work on the intermetallic phase formation and the mechanical strength of the joints were investigated. In this work, the maximum shear load obtained was 6460 N and the presence of the intermetallic phases had reduced the shear strength of the brazed joints. However, the torch brazing process using Al-Si-Zn filler metal had successfully facilitated the joining of these dissimilar metals.

The joining of aluminium alloys to steels has been extensively studied, especially in the automotive sector. However, aluminium alloys are known to be difficult to join with steels when methods involving fusion welding are used because of the hot cracking problem. Hence, a high-strength joint between these dissimilar metals would be of benefit especially in reducing the weight of products. In this work, the torch-brazing method was applied to join AR500 steel with AA7075 aluminium alloy using Al–Si–Zn base filler metal at various flame times. The effects of the brazing work on the intermetallic phase formation and the mechanical strength of the joints were investigated. In this work, the maximum shear load obtained was 6460 N and the presence of the intermetallic phases had reduced the shear strength of the brazed joints.

Gtaw Process

This study involves V-groove butt welding of CP Titanium to 304 stainless steel by the gas tungsten arc welding (GTAW) process without and with buttering layer at the 304 stainless steel base metal. ERCuSn-A and ERNiCu-7 were chosen as a filler metals. Investigations including visual testing (VT), microhardness testing and metallurgical analysis were carried out by means of variable welding parameters. The experimental results showed that using the ERCuSn-A filler metal without and with buttering layer, any surface defect was not observed in the dissimilar metals welded specimen but an underbead crack was found at weld metal adjacent to the Ti/weld metal interface. Using the ERNiCu-7 filler metal without buttering layer, linear porosity was observed at weldment. However, using ERNiCu-7 filler metal with buttering layer, defect-free welded specimen could be achieved. The results of EDS analysis indicated that at Ti/weld metal interface, Ti diffused from the Ti base metal to the weld metal. At 304 stainless steel/weld metal interface, Fe, Ni and Cr diffused from the 304 stainless steel base metal to the weld metal.

Phase Constitution

Joining Cu to Al has been carried out by vacuum contact reactive brazing without filler metal. Experimental results obtained showed that the eutectic structure and some Cu-Al intermetallic compounds were the main phases of the braze seam. The fracture surface of the joint presented typical brittle fracture for the existence of intermetallic compounds at the interface and the shear strength could reach 65MPa.
