研究了在1 tec 2 mm厚的AA 5182-O铝合金板上采用双面电弧焊（DSAW）方法进行拼焊板对接方焊缝的可行性和优点。全熔透，传导模式DSAW焊缝使用平衡方波AC，恒流电源在30至40 mm s-1的焊接速度时，使用2 stec 1 kW的焊接功率和40和60 mm s-1之间时，使用3 stec 4 kW的焊接功率。钢板两面的氧化物得到了良好的阴极清洗，焊缝质量和性能优良。所有焊缝均表现出柱状晶向等轴晶的过渡，等轴晶面积高达40%。DSAW工艺被发现能够产生相同或更好质量的焊缝，并且焊接速度与使用更传统的焊接工艺用于TWB应用所产生的焊接速度相当。
The feasibility and merits of using the double sided arc welding (DSAW) process for making square welds in 1˙2 mm thick AA5182-O aluminium sheets in the butt-joint configuration for applications such as tailor welded blanks (TWB) has been studied. Full penetration, conduction mode DSAW welds were made using a balanced square wave AC, constant current power supply at welding speeds of 30 to 40 mm s–1 when using 2˙1 kW welding power and between 40 and 60 mm s–1 when using 3˙4 kW welding power. There was good cathodic cleaning of the oxide on both sides of the sheet and the weld bead quality and properties were excellent. All welds exhibited a columnar to equiaxed grain transition with up to 40% equiaxed grain area. The DSAW process was found to be capable of producing welds of equal or better quality and at comparable welding speeds to those produced using more traditional welding processes for TWB applications.
