The experiment shows that by using inverter spot welding, the average intensity of the welded spot is increased while the splash rate and the incompletepenetration rate are descend.
实验结果显示，采用逆变焊机进行焊接，焊点的平均强度有所提高，飞溅率和未焊合率均有大幅度降低。

Based on plenty of account data, engineering estimated formulas for plastic limit internal pressure were fitted for welded pipe branch junction with incompletepenetration along intersecting line.
