The flash butt welding machine can effectively remove impurities and iron oxide at the joint, and the welding quality is stronger than that of the resistance welding machine. The welding excuse of the flash welding machine is relatively strong.
What are the main components of the butt welding machine?
What is the working principle of the butt welding machine?
What precautions should be taken when using the butt welding machine?
The butt welding machines generally do not use welding rods, but weld the two metal parts directly together.
Usually used resistance welding is the use of a high resistance at the contact point, and the temperature of the material at the contact point is increased up close to the melting point when it is supplied with energy, and then put under pressure to connect them.
There are also friction welds: the use of a high-speed rotation of the two contact ends, the high temperature generated by the friction increases the temperature of the material at the contact until close to the melting point and then puts it under pressure to connect them.
The use of butt welding machines has a wide range of applications.Basically, all metal materials that can be forged can be welded by flame-retardant welding.For example, low-carbon steel, low-carbon steel, alloy steel, stainless steel and other non-ferrous metals and alloys can be welded by welding the exhaust pipe.
The welding interface of the butt welding machine is large, in general it can be welded from ten to ten thousand mm cross-section area.
Combustion pump welding is common when welding different plates, pipes, profiles, solid parts, cutting tools, etc.used.It is widely used and is an economical and efficient welding process.
1. Set the distance between the two cheeks of the plunger welding machine. Turn the adjusting screw so that the distance between the cheeks, when the joystick is at the left stop, corresponds to the difference between the total length of the two welds and the amount of extrusion.If the joystick is at the right stop, the distance between the cheeks should correspond to the total length of the two welds plus 2 to 3 mm, which corresponds to the original position before welding.
2. Set the short circuit end switch so that the butt welding machine can automatically switch off the current when the welding is finished (when the predetermined amount of pressure is reached).
3. Adjust the cheeks according to the shape of the welding structure so that the two cheeks are at the same height and then clamp the welding structure.
4. In order to avoid instantaneous overheating of the welding structure, the number of adjustment steps during sample welding should be gradually increased and the appropriate secondary voltage selected. A higher secondary voltage should be used for exhaust welding.
5. In order to avoid overheating the parts during welding, the cooling water valve must be opened and water supplied before welding.In order to facilitate inspection, a funnel is located on the left front of the butt welding machine which can directly monitor the water flow to check if cooling water flows through the inside of the butt welding machine.
The butt welding machine has taken an irreplaceable position in industrial production.WELPING strives to provide all customers from all over the world with various high-quality butt welding machines.
