What are the positive and negative impacts of cultural penetration?───哪些正面和负面影响的文化渗透?
The surface tension, arc blow force and electromagnetic force work positive to improve the penetration, and the buoyancy can increase the width in the middle of weld pool.───表面张力、电弧吹力和电磁搅拌力均有利于获得较大的熔深,浮力有利于增加焊缝中间部位的宽度。
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;───当负极性比率等于零即直流且焊丝为正极性的MIG焊时,其焊缝熔深最大,焊丝熔化系数最小,熔敷速度最小;
