Influence of New Welding Technology and Wire Type on Welding Reliability of Aluminum Alloy 6061-6101

Aluminum alloy materials have low melting point and high plasticity, therefore, in the field of material welding has been widely used. In order to study the influence of new welding process parameters on the welding reliability of aluminum alloy materials (6061-6101), this paper studied the welding properties of four kinds of welding wires under the condition of new welding process parameters (100A welding current, welding speed of 5mm/s). The results showed that compared with the traditional welding process, the new welding process increased the speed by 2.5 times and reduced the welding current by 1 times. The welding reliability meets the design requirement. The welding wires (ER5356, ER4043) have no obvious bubble in the weld area. The maximum tensile strength of the four types of wire is 141.14MPa, which is 1.6 times of the yield limit. The new welding parameters have good tensile resistance for aluminum alloy materials. No obvious corrosion defects were found in the corrosion test.
