No, they are not the same.
A spot welding machine presses the workpiece with electrodes, and the transformer outputs current. The current flowing through the workpiece generates resistance heat, heating the contact area to a molten or plastic state and forming a strong weld nugget. A spot welding machine is resistance welding equipment that uses electrodes to create weld spots on the workpiece.
A rivet welding machine uses a punch similar to a piercing pin to press a small boss through two parts and rivet them together. Rivet welding machines are also used for heat riveting, shaping, or hot melt embedding. They need a hot melt die and a workpiece locating die that match the parts to be welded.
The two differ in heat generation. Spot welding is internal heat. Rivet welding is external heat.
We can machine custom electrodes, punches, fixtures, locating dies, and other precision parts for spot welding and rivet welding machines from customer drawings, for single-piece or low-volume production.
Our custom precision component machining capability is not limited to spot welding and rivet welding equipment. Beyond electrodes, punches, fixtures, and locating dies, we also machine yacht precision components, RC car structural parts, medical device parts, and non-standard parts for food machinery, textile machinery, and printing machinery. Hansheng Automation works from customer drawings and production quantities to deliver single-piece or low-volume precision machining.
