Resistance Butt Welding MachinesMachines Characteristics,butt welding machine

Resistance BUTT welding machines clamp the parts in jaws firmly, press the parts against each other and pass AC electrical current. Once metal start melting on the surface, machine quickly applies upset force to join the pieces together.

Welding process is simple and produces good results, minimum burrs on the outside of the joint.

Welding jaws are designed in such a way to simplify clamping parts for welding.

Special Butt weld control circuits assure weld quality and repeatability

Resistance Butt Welding Machines are mainly used for welding steel wire, pipes, etc. with a small cross-section (not to exceed 250mm2)

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: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.

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.
