摘要
在裂纹前沿钻止裂孔能有效控制裂纹扩展．作者对用上述方法提高焊接构件疲劳寿命作了理论分析，实验结果令人满意．
Drilling a crack-catting hole in front of a crack is an effective way to control the crack growth. The principle of using crack-cutting holes in increasing the fatigue life of welding components is analyzed in the paper. the experiment results are satisfactory.
