Spot and projection welders are generally referred to as resistance welders. The essential difference between spot or projection welding is the different welding processes and the
1. The surface of the workpiece is not clean. 2. Electrode surface is not flat or sticky with welding metal. 3. Poorly adjusted welding specification. 4. Electrode indentation is t
The principle of the capacitor discharge spot welder is to charge a group of high capacity capacitors in advance by a smaller transformer and then discharge the welded parts by a h
Technical engineers who often use spot welding machines should be familiar with the commonly used metal spot welding parameters. First, to improve the efficiency of spot welding op
In the opinion of the resistance welding machine manufacturer, the seam welder works on the same principle as spot welding and is a resistance welding technology. The welded parts
With the use of high-strength and hot-formed steel sheets in the automotive and sheet metal industries, the advantages of the capacitor discharge welder for projection welding are
Since the discharge time of the capacitor discharge welder cannot be adjusted, only pressure and current can be adjusted and controlled among the three elements of welding (pressur
