I will ask the factory pay attention to this and the welding is better than this .
but for this order ,we can not use the welding robot ,only the beam' quantity is more than 3000 pcs ,then the factory will use the welding robot ,because the welding robot is very fast ,if the quantity is small ,it can be finished very fast ,only the quantity is big then the factory will use the robot .
But i will tell the woker weld more better than the sample .
