distortion in weldments
hanjle blanxing 焊接变形(distortion in weldments)全属 焊接时或焊接后，由于不均匀加热和不均匀冷却引起 的金属焊接结构的变形。焊接变形大致可分为8类: (l)纵向收缩变形。构件焊后在焊缝方向发生收缩，如 图1中的△乙。(2)横向收缩变形。构件焊后在垂直焊缝 方向发生收缩，如图1中的△召。(3)弯曲变形(图2)。 构件焊后发生弯曲。弯曲可由焊缝的纵向收缩引起，也 可由焊缝横向收缩引起。(4)角变形(图3)。焊后构件堰票到{副}渠囊到+目{ 图1纵向和横向收缩变形的平面围绕焊缝产生的角位移。(5)波浪变形(图4)。焊后构件呈波浪形，在薄板焊接时最容易发生。(6)错边变形(图5)。在焊接过程中，两焊接件的热膨胀不一致，可能引起长度方向上的错边和厚度方向上的错边。(7)扭转变形(图6)。焊后在结构上出现的扭曲。(8)张开变形(图7)。平板对接时，焊炬前方出现张开现象。一窿白一‘ 之立童鱼宝 b 图2弯曲变形 a一焊缝纵向收缩引起;b一焊缝横向收缩引起 一甲 图3角变形处遥乡、气蛋建乡 图4波浪变形业久二多酬 ab 图5错边变形 a一无点固泌一有点固 霆葬冀霎 图6扭转变形巨弓 图7张开变形
