The projection welding of the projection welding machine is applied (when the ball is bumped), the thickness of the veneer is 1-3.5mm; (when the cone is bumped), the thickness of the veneer is 2.5-8.0mm; aluminum is only the hardest alloy with the largest thickness (3+ 3) mm; in addition to convex welding of plates; there are also convex welding of nuts, screws, wire crosses, pipes, T-shapes, etc.
Projection welding is used in applications with high thickness ratios (such as welding nuts to thin plates); and in applications where the appearance of the thin plate must be controlled (such as the surface of some appliances).
The main application of projection welding is to connect some stamped low carbon steel, low alloy steel and HSLA steel parts. During stamping (punching, drawing, or forming), one of the parts must be formed into a protrusion in the stamping process, so as to perform projection welding.
Projection welding can also be used to connect the cut threaded part to the stamped part, and the protrusion can be processed by cutting or cold forming at the end of the cut threaded part.
Projection welding is most successful on parts with thicknesses ranging from 0.56 to 3.18 mm (0.022 to 0.125 in). When a 0.25mm (0.010in) thick blank is used for projection welding, the design of the projection is the key, and a welding head with a small inertia and a fast follower are needed.
