What's the difference between spot welder and projection welder?Hwashi experts tell you!

 

The difference between a projection welder and a spot welder is that the projection welder workpiece needs to be pre-manufactured into a projection block of a certain shape and size. The size of the current path area during welding is determined by the size of the bump, not by the size on the electric extreme surface like spot welding. As a result, the size of the end face of the projection weld electrode can be increased and the current density in the electrode can be reduced, so that higher strength and lower conductivity can be selected.

 

Projection welding is mainly used for welding low carbon steel and alloy steel stamping parts.There are many types of projection welding.In addition to plate projection welding, there are nut and screw projection welding, line cross projection welding, tube projection welding and T plate projection welding.

 

The most suitable thickness for plate projection welding is 0.5 ~ 4mm.When welding thin plates, the projection design requirements are very strict, and the welder is required to have excellent follow.Therefore, spot welding is more suitable for plate thickness less than 0.25mm.
