What is butt welding machine?

The butt welding machine is also called current welding machine or resistance welding machine. Using the resistance between the contact surfaces of the two work pieces, a low voltage and large current is instantly passed through, so that the contact surfaces of the two mating metals instantly heat to melt and fuse.

What is the general power of a butt welding machine?

The butt welding machine generally mark your power on the nameplate. 22.8kva is its maximum power consumption. If you wire the welder, you must calculate it based on this capacity. If you want to calculate the power consumption, you must calculate it based on the actual welding current. 22.8KVA refers to the apparent power. The power factor of the AC welding machine generally does not exceed 0.8. Therefore, when the maximum welding current is 300A, the input active power is 22.8*0.8=18.24KW. Since there is only a 35% duty cycle when the output is 300A, then you can only weld 35% of the time per hour, which is 18.24KWH*0.35=6.384 degrees, which means that your butt welding machine is needed. No matter how you solder the machine, the power consumption per hour will not exceed 7.98 degrees.

What are the main butt welding machines commonly used in industrial and mining enterprises?

At present, the main butt welding machines used by industrial and mining enterprises are: AC arc welding machine, DC electric welding machine, argon arc welding machine, carbon dioxide shielded welding machine, butt welding machine, spot welding machine, submerged arc welding machine, high frequency welding machine, flash pair Welding machine, pressure welding machine, butt welding machine, laser welding machine

What are the use processes of the butt welding machine?

Continuous flash welding: The technological process of the butt welding machine includes continuous and upsetting. First, the circuit is closed and the end surface of the workpiece is slightly contacted. At this time, metal particles similar to sparks will be ejected in the gap of the end surface-that is, flash.

Preheating flash welding: The process of the butt welding machine includes preheating, flashing, secondary flashing and upsetting. One flash is to flash the end surface of the workpiece flat, while continuous flash preheating is to slightly contact and separate the two ends of the steel bar. Intermittent flashes are emitted to achieve the warm-up effect.

Flash butt welding process: the butt welding parameters can be divided into parameters (high current and short time) and weak conditions (small current and long time) according to the difference of current and time. butt welding machine adopts strong parameters. Reduce joint overheating and improve welding efficiency, but it is easy to produce hardening.
