The Role Of Pressure In The Operation Of The Spot Welder

Because of the convenience of spot welding machine operation, many companies that process sheet metal i generally choose spot welding machines as the main welding machine. However, there are many spot welding machine types on the market. How to choose them is also a problem. Let ’s talk about spot welding. Machine selection elements. When the spot welder is operating, it has a lot to do with the size of the current, the welding time, and the welding pressure.

The pressure systems of traditional spot welding machines include foot-operated (manual), cam (motor), pneumatic (external air source), and a few hydraulic (usually used in vacuum dispersion welding).

The effect of pressure in the operation of spot welding machines is often overlooked by most people. When the melting point forms a welding nugget, too large or too small a pressure will form a crack in the welding nugget, and excessive pressure will also cause shrinkage. It is required that the follow-up of the pressurized system is good, that is, it is suspended at any time. A good pressure curve is the foundation of a good spot welder. In order to avoid the cylinder body adopting linear bearings as the medium for pressure transmission, it is very ambitious. The current adopts closed-loop control.
