The main workpieces that need to be quenched after flash butt welding are steel, aluminum alloys and copper alloys. The main function of quenching is to increase the rigidity, hardness, wear resistance, corrosion resistance, fatigue strength and toughness of the metal.

The main workpieces that need to be tempered after flash butt welding are steel and copper. The function of tempering is to reduce the brittleness of the metal, eliminate or reduce internal stress, obtain the required mechanical properties, stabilize the size of the workpiece, and facilitate cutting. Xinxing editor also often sees direct tempering after butt welding.

In flash butt welding or resistance butt welding, due to the influence of the resistance heat source that changes the workpiece port section from solid to liquid to fused solid, the structure and properties of metals and alloys after welding will undergo some changes. Therefore, if we understand the chemical composition and properties of metal and alloy welded joints, we can understand how they can be used during welding.

Most of the automatic flash butt welding machines adopt the vertical head-out type, which is more user-friendly and can connect various metal pipes, flange pads, flat irons, copper and aluminum rows, etc. The appropriate power can be selected according to the size of the pipe diameter or the cross-sectional area of the workpiece, or the matching power model can be customized.

Flash butt welding machine, also known as flash butt welding machine, is a type of resistance welding machine. The principle is that two metal workpiece ports are in contact, conduct electricity through the contact points of the ports, and then use the resistance heat of the workpiece itself to heat the workpiece and flash continuously to weld.

The automatic iron pipe flash butt welding machine is most often used to butt square pipes, round pipes, stainless steel pipes, flange pads, copper and aluminum rows, etc. in furniture manufacturing, pipeline engineering, boiler manufacturing and petroleum equipment production. Its advantage is flash.

Vertical automatic flash butt welding machine is a resistance welding machine. It is designed and manufactured by Xinxing specifically for butting various types of metal pipes, such as furniture pipes, iron pipes, galvanized pipes, stainless steel pipes, aluminum pipes, copper pipes, semi-circular pipes, round pipes, flat pipes, rectangular pipes, special-shaped pipes, welded pipes, cold drawn pipes, fan-shaped pipes, Q195 pipes, Q235 pipes, etc.

The copper and aluminum pipe butt welding machine of the pneumatic butt welding machine appears uneven when using the mold. This editor of Xinxing has indeed seen many, especially new molds. Things to pay attention to

Before welding copper and aluminum pipes with a copper-aluminum pipe butt welder, the copper pipe must be shrunk first to facilitate the insertion of the aluminum pipe, and to control the burrs in the oblique seam between the copper pipe and the aluminum pipe without affecting use. Then shrinking the tube requires the use of special equipment, namely the tube shrinking machine, the shrinking machine and the heading machine.
