摘　　要：研究了水下湿法焊对接接头间隙与裂纹率的关系。随着接头间隙的增大 ,裂纹率逐渐减少。当间隙增大到一定值 ,可防止冷裂纹的产生。因此 。Relationship between butt joint gap and cold crack rate of 16 Mn steel underwater wet welding is studied. When the gap of butt joint increases, cold crack rate gradually decreases. It shows that cold cracks can be avoided by using appropriate joint gap.$$$$
