- 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
- Welding faces the challenge of high strength steel plates.Welding process of galvanized steel sheet and multilayer steel plate.Application of aluminum alloy sheet material.The widespread use of automatic flexible production line for welding robot.Continuously reduce energy costs, quality costs, and maintenance costs.
- Q: What is the working principle of the suspension type resistance welding machine?
- The workpiece welding end welding procedures after the transformer primary coil power, welding machine into "maintenance" program, the pressure to be maintained for a period of time, the solenoid valve opens, releasing the workpiece holder, welding machine into the "rest" program. A welding cycle has been completed at this time.
