Spot welding method roller conveyor

Spot welding is to be worn at the welding filler recess . Simple and practical method roller conveyor , without affecting production , automated sorting machine and the surfacing parts of the hardness

and good wear resistance , roller conveyor Incline Belt conveyor drawback is only suitable for the roll and good solderability ( eg steel roll ) .
Surfacing should note the following:
Lift the drum roll bar to select the appropriate surfacing to use the heap and heap 266 256 is appropriate.
Lifts should be chosen drum roller surfacing of small diameter , low current welding specifications , stratified surfacing. This reduces the thermal stress , to avoid severe

deformation and cracking
