It pushes lower and moves down in place, one of soldering turret electrode is in contact with fixed copper coin, and ensures that the electrode is filled with fixed copper coin
Tap is touched, while soldering turret another electrode is also moved, and until the electrode touches bond pad locations, galvanization carries out at this time
The welding of the bond pad locations, after the completion of welding at this solder joint soldering turret return;
(3) when needing persistently to weld remaining solder joint on door skin and inner plate of car door, it is corresponding to start other solder joints
Soldering turret, and then realize and corresponding solder joint is welded, welding step can be carried out according to such as the same mode of step (2)
Operation, and then realize the welding of each solder joint, ensure the completion of door skin and inner plate of car door welding;
(4) after the completion of step (3), the welding of a door skin and inner plate of car door is completed, other vehicles are welded if necessary to repeat
External door panel and inner plate of car door repeat step (1)-(3).
