钢结构工程所谓焊(han)(han)(han)接(jie)变(bian)(bian)(bian)形(xing)(xing)(xing)(xing)(xing)(xing)是(shi)指钢(gang)结(jie)构(gou)在焊(han)(han)(han)接(jie)过程(cheng)中，由(you)于(yu)施焊(han)(han)(han)电弧高温(wen)引起的(de)变(bian)(bian)(bian)形(xing)(xing)(xing)(xing)(xing)(xing)，以及焊(han)(han)(han)接(jie)完成后在构(gou)件(jian)中的(de)残余变(bian)(bian)(bian)形(xing)(xing)(xing)(xing)(xing)(xing)现象(xiang)。在这两类变(bian)(bian)(bian)形(xing)(xing)(xing)(xing)(xing)(xing)中，焊(han)(han)(han)接(jie)残余变(bian)(bian)(bian)形(xing)(xing)(xing)(xing)(xing)(xing)是(shi)影响(xiang)焊(han)(han)(han)接(jie)质量的(de)主要因素，🍸也是(shi)破坏性(xing)最强的(de)变(bian)(bian)(bian)形(xing)(xing)(xing)(xing)(xing)(xing)类型(xing)。焊(han)(han)(han)接(jie)残余变(bian)(bian)(bian)形(xing)(xing)(xing)(xing)(xing)(xing)对(dui)结(jie)构(gou)的(de)不(bu)(bu)同(tong)层次的(de)影响(xiang)分为(wei)(wei)整体变(bian)(bian)(bian)形(xing)(xing)(xing)(xing)(xing)(xing)和局部(bu)变(bian)(bian)(bian)形(xing)(xing)(xing)(xing)(xing)(xing)；根(gen)据变(bian)(bian)(bian)形(xing)(xing)(xing)(xing)(xing)(xing)的(de)不(bu)(bu)同(tong)特点则可分为(wei)(wei)：角(jiao)变(bian)(bian)(bian)形(xing)(xing)(xing)(xing)(xing)(xing)、弯曲(qu)变(bian)(bian)(bian)形(xing)(xing)(xing)(xing)(xing)(xing)、收缩变(bian)(bian)(bian)形(xing)(xing)(xing)(xing)(xing)(xing)、扭曲(qu)变(bian)(bian)(bian)形(xing)(xing)(xing)(xing)(xing)(xing)、波浪(lang)变(bian)(bian)(bian)形(xing)(xing)(xing)(xing)(xing)(xing)和错边(bian)变(bian)(bian)(bian)形(xing)(xing)(xing)(xing)(xing)(xing)。在这些变(bian)(bian)(bian)形(xing)(xing)(xing)(xing)(xing)(xing)类型(xing)中，角(jiao)变(bian)(bian)(bian)形(xing)(xing)(xing)(xing)(xing)(xing)和波浪(lang)变(bian)(bian)(bian)形(xing)(xing)(xing)(xing)(xing)(xing)属于(yu)局部(bu)变(bian)(bian)(bian)形(xing)(xing)(xing)(xing)(xing)(xing)，而其(qi)他(ta)类型(xing)的(de)变(bian)(bian)(bian)形(xing)(xing)(xing)(xing)(xing)(xing)属于(yu)整体变(bian)(bian)(bian)形(xing)(xing)(xing)(xing)(xing)(xing)。钢(gang)结(jie)构(gou)发生较多的(de)变(bian)(bian)(bian)形(xing)(xing)(xing)(xing)(xing)(xing)类型(xing)是(shi)整体变(bian)(bian)(bian)形(xing)(xing)(xing)(xing)(xing)(xing)。
