在焊接接头纵向冷弯试验时,对弯轴直径与试件厚度n值作了研究。认为,n值是影响冷弯检验程度的主要参数,而不是冷弯角α。
In the cold bending test of welded joints, the bending axis diameter and specimen thickness n values were studied. It is considered that the value of n is the main parameter that affects the degree of cold-bend test, not the cold-bend angle α.
