- Q: What are the characteristics of constant voltage operation mode of medium frequency resistance welding machine?
- Advantages of intermediate frequency resistance welding machine:The power factor is extremely high (above 0.95), and the required power supply is saved by half compared with the AC resistance welder, and the three-phase balance of the power network is not influenced.Because of the direct current bunching effect and no zero crossing effect, the welding efficiency is improved and the required current is smaller. Therefore, the required cooling water is less, and the spatter is reduced, so that the electrode grinding cycle is lengthened correspondingly.If a transformer power frequency transformer size and weight can be reduced to one - to 1/3.The secondary loop is not affected by the ferromagnetism of the workpiece.There is no alternating electromagnetic force in the DC operation, so the electrode pressure is less.
- 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?
- During the operation of the spot welding machine, the time control of the pressure, welding, maintenance and rest procedures is completed by the time regulator in the spot welder controller. The length of time required for each program and the size of the welding current (i.e., welding specification) shall be preset in accordance with the welding procedure.
