6061铝合金薄板焊接应力与焊接变形OACSTPCD
Welding Stress and Welding Distortion of 6061 Aluminium Alloy Thin Plate
研究了6061铝合金薄板TIG焊焊接应力、焊接变形与焊接电流、焊接电压和板材尺寸的关系.随着焊接线能量的增加,铝合金的纵向和横向收缩变形增加；随着板的长度的增加,由于约束增加,板的纵向残余变形减少,厚度方向的抗弯增大,横向变形增大.板焊后,焊缝处受拉应力,而紧靠焊缝的母材处却受压应力,其余部分受拉应力且焊接线能量越大,残余应力越大.
the relationship between the plate size, welding current, welding voltage and welding stress, the welding distortion for 6061 aluminum alloy sheet TIG welding is studied. With the increase of welding current, welding voltage,aluminium alloy of the longitudinal and lateral contraction deformation increase; With the increase of the length of the plate, due to the much more constraint, the plate of the longitudinal residual deformation decrease,for the bending …查看全部>>
