maximum penetration rate
常见例句
- When electrode negative ratio is zero, which is using MIG welding with DC ami welding wire being positive polarity, weld penetration is maximum , wire melting speed and deposition rate are minimum;
儅負極性比率等於零即直流且銲絲爲正極性的MIG銲時，其銲縫熔深最大，銲絲熔化系數最小，熔敷速度最小； 返回 maximum penetration rate
