The principle of butt welding

Butt welding is resistance welding, also called contact welding. It is a metal connection method that presses the workpiece between the electrodes of the welding machine and energizes the workpiece itself to generate resistance heat. The resistance heat accumulates to the temperature of plastic deformation, and then is vertically pressurized or transversely forged. A metal connection method. It includes: spot welding, butt welding, projection welding, seam welding (roll welding), etc.

Why do spot welding and projection welding produce spatter?
Company & Project News · 2022-06-21

Why do spot welding and projection welding produce spatter?

The spatter during spot welding is caused by the expansion of the metal at the welded area when resistance spot welding or projection welding is heated, forming liquefied metal and plastic rings. They continue to grow under the influence of temperature, causing the air pressure in the melting zone to continue to increase. The uneven wall thickness of the plastic ring allows liquid to overflow.

I don’t like the appearance color of the spot welding machine. Can I change the color?

This problem has indeed been encountered in reality. Many customers will ask to change the color of the spot welding machine for the overall aesthetics and consistency of the workshop equipment. Some individuals also have their own preferences and want the resistance spot welding machine to be spray-molded in the color they want. It is still possible to change the color, although it has a certain strength.
