1. Automotive aluminum alloy wheels have argon arc welding, electric welding, and gas welding. The welding effect of these welding methods is that argon arc welding is better than electric welding,...

In the welding process of fully automatic flash butt welding machines, defects such as welds, solder joints, and arc pits often occur due to external or internal factors. This is the reason for the...

The medium frequency spot welding machine is energized based on the pressure of the electrode on the welded part, and generates Joule heat (instantaneous) based on the contact resistance between the e

1. The secondary voltage of intermediate frequency DC spot welding machines is generally relatively low, and there is no risk of electric shock. But the primary voltage is high voltage, and the primar

Resistance spot welding machine is a kind of equipment that uses Joule heat generated by electrified electrode to weld workpiece instantaneously, so as to achieve rapid welding of workpiece. Especiall

The energy storage spot welding machine industry trend research report is based on the investigation and analysis of many factors that affect the market operation of the energy storage spot welding ma

The principle of resistance welding: pressure is applied through the electrodes after the weldment is assembled, and the current is used to connect through the joint; 1. The output of welding heat and

​1. AC spot welding machine 1. The AC spot welder is a machine that can weld the workpieces firmly. The AC spot welding machine is composed of a step-down transformer, a current regulator, a heat dis

In industrial production, AC spot welding machines are widely used in aviation, automobiles, boilers, subways, vehicles, measuring tools, radio devices and other fields. At present, the power frequenc

The process of spot welding is to open the cooling water; clean the surface of the weldment, and after the assembly is accurate, send it between the upper and lower electrodes, apply pressure to make
