- Q: What are the characteristics of constant voltage operation mode of medium frequency resistance welding machine?
- If the frequency sampling rate is high (usually minimum adjustment cycle 0.25ms~1ms), it is easy to control the welding process accurately and flexibly.The control modes of medium frequency direct current resistance welding machine include constant current control mode, constant voltage control mode and constant power mode, and some products have fixed pulse width control mode.Constant voltage mode features: constant voltage, less current in the second half. The reason is that when the workpiece is heated, the resistance increases, so that the current decreases. The aim of the model is to keep the joint temperature stable rather than increasing.
- Q: Comparison between medium frequency spot welder and common resistance welder
- Long term problems in general resistance welding:Instability of welding quality.Spatter during welding.Lack of effective data monitoring for welding quality.Excessive wear of electrodes.The power factor is low, and a large number of capacitor compensation cabinets are added to improve the power factor.
- Q: What is the working principle of the suspension type resistance welding machine?
- The spot welding, the workpiece is located between the electrode holder first, and then press the welding switch, "start pressure" program, the electromagnetic valve action, compressed air into the cylinder so that the electrode holder welding, the workpiece clamping action, after appropriate delay, "start welding procedures" at this time, the primary coil of the transformer through the control and power supply connect the SCR welding welding current, secondary
