Welding knowledge
How to resistance braze pure copper
Pure copper easily produces copper oxide and cuprous oxide during resistance brazing, but they are not difficult to remove with flux, so the weldability is good.
Resistor brazing brass
Brass is a copper-zinc alloy. Zinc oxide and cuprous oxide are easily generated on the surface during resistance brazing at high temperatures. Although zinc oxide is relatively firmly bonded, it is relatively easy to remove with flux, so it does not affect the weldability.
Resistance brazing tool steel
Tool steel generally includes medium and low carbon steel tool steel, alloy steel and high-speed steel. In the high temperature of resistance brazing, their structure and properties are prone to problems of annealing, oxidation and decarburization.
How large should the gap be left for resistance soldering joints?
If you want the strength and density of brazing to meet standards, the size of the gap must be controlled well. If the gap is too large, it will be difficult to fill it with solder, resulting in weak welding and poor strength. The gap is too small and it is difficult for the solder to penetrate into it.
How to adjust welding parameters in resistance brazing
Xinxing Welding's resistance brazing machine has few parameters and is easy to operate. There is only one important parameter, which is the welding current.
How to operate resistance brazing
The operation of resistance brazing is very different from that of resistance spot welding. Resistance brazing needs to maintain a high temperature for a certain period of time to melt the filler metal, while spot welding requires heating to the melting point of the base metal before forging, so the operation is also different.
Spot welding of hardware drawers
Hardware drawers are generally used in tool boxes, office desks, wardrobes, cabinet baskets, etc. The materials include mild steel, iron sheet, stainless steel, etc. Their connection lengths are generally relatively long, and they are still in the welding box and require a customized spot welding machine for welding.
Is diffusion welding equal to resistance brazing?
Yes, diffusion welding is resistance brazing. Common copper connecting wires are welded with it. It is to stack dozens or hundreds of copper sheets together and compress them, and then energize and heat them below the melting point, using the mutual diffusion between atoms to achieve a certain depth of connection.
Principles and characteristics of resistance brazing
Brazing is a connection method that maintains the temperature between higher than the melting point of the solder and lower than the melting point of the base metal, fills the gap between the base metal by melting the solder, and solidifies and crystallizes to achieve interatomic bonding. And resistance brazing is. . . . .

What should I do if the copper and aluminum pipe butt welding machine is not flat when using the mold?
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
What are the characteristics of the copper pipe shrinking machine matched with the Xinxing copper and aluminum pipe butt welding machine?
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.
What should be inspected after welding copper and aluminum pipes with a butt welding machine?
Copper and aluminum pipes are also called sleeve joints and copper-aluminum connecting pipes. They are mainly welded with special butt welding machines, such as pneumatic copper and aluminum pipe welding machines and automatic copper and aluminum pipe butt welding machines produced by Xinxing Welding. They are mainly used in refrigeration industries such as refrigerators and air conditioners. Their requirements are relatively high and there are many inspection items.
Brief analysis of copper and aluminum pipe welding process
Before looking at the welding process of the copper-aluminum pipe butt welding machine, let's talk about why we use copper-aluminum pipes. It is to weld a section of copper pipe, that is, a copper-aluminum pipe, at both ends of the aluminum pipe. In this way, the copper pipe is still connected to the copper valve during installation, because there will be no corrosion problems.
What is the welding process of copper and aluminum pipe butt welding machine?
The welding process of Xinxing copper and aluminum pipe butt welding machine is the action state of each component. It includes several different actions in completing an action cycle, and then determines the switching signal after each action.
Introduction to Xinxing Copper and Aluminum Pipe Butt Welding Machine
The copper-aluminum pipe butt welding machine in the resistance pneumatic butt welding machine is widely used in refrigeration industries such as refrigerators and automobile air conditioners. It is a special equipment for welding copper and aluminum pipe joints. There are standard machines, non-standard machines and high-end machines.
