摘要

采用高频脉冲MIG焊和常规脉冲MIG焊进行了6082-T6铝合金8 mm厚板的对接焊工艺试验（焊接接头条件：焊接间隙1 mm，钝边为0.5 mm、坡口角度分别为50°和60°），对比分析了焊缝成形规律及焊后焊趾处的残余应力值。研究结果表明：两种焊接方法的焊缝成形质量良好，与常规脉冲MIG焊相比，高频脉冲MIG焊根部熔深较大，坡口角度为50°时，在相同的热输入（10.7 kJ/cm）条件下，根部熔宽增加约20%，坡口角度60°时，根部熔宽增加约16%；与常规脉冲MIG焊相比，高频脉冲MIG焊的气孔敏感性较小，焊接残余应力较小。坡口角度为60°时，横向残余应力（,σ,y,）降低约为18.5%，纵向残余应力（,σ,x,）下降约为8.3%；坡口角度为50°，横向残余应力（,σ,y,）降低约为18%，纵向残余应力（,σ,x,）下降约为7%；坡口角度由60°减小为50°，高频脉冲焊焊趾处的残余应力下降约6%。

Abstract

In this paper,welding procerure test of 6082 aluminum alloy medium plate butt joint were done using high-frequency pulse MIG welding and conventional pulse MIG welding processes with a 1 mm gap, plate thickness 8 mm, and a groove angle of 50° and 60° respectively; The macroscopic morphology of welded joints(welding appearance)and the residual stress at welding toe after welding were studied. The experimental results showed that welding appearance were better for two welding processes, compared with conventional pulse MIG welding process,high-frequency pulse MIG welding process possessed deeper penetration,wider fusion width,lower porosity sensitivity and welding residual stress. Compared with conventional pulse MIG welding process,when groove angle was 50°,at the same welding heat imput(10.7 kJ/cm),root fusion width increased about 20% by high-frequency pulse MIG welding process,about 16% when 60° groove angle.Transverse residual stress(,σ,y,) at welding toe decreased about 18.5% when groove angle was 60° by high-frequency pulse MIG welding process,about 8.5% for longitudinal residual stress(,σ,x,).When groove angle was 50°,transverse residual stress(,σ,y,) at welding toe decreased about 18% ,7% for longitudinal residual stress(,σ,x,) by high-frequency pulse MIG welding process.Decreased from 60° to 50° for groove angle ,residual stress at welding toe decreased about 6% by high-frequency pulse MIG welding.
