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.

NOVEL WELDER's resistance brazing machine has few parameters and is easy to operate. There is only one important parameter, which is the welding current.

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.

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.....
Read articleYes, 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.

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.

Common butt welding methods for aluminum alloys include spot welding and butt welding. The 3457 series butt welding is easier and can be done with a resistance AC butt welding machine. The added elements in the 126 series are not resistance weldable. For spot welding in touch welding, no matter which series it is, it is more difficult.
Read articleNickel-based alloys are high-temperature alloys, also known as superalloys. Its main elements are copper, chromium, and molybdenum. They have high strength, corrosion resistance, and oxidation resistance at high temperatures, and have good weldability. They are generally used as coating materials.

The butt welding of copper and copper alloys is better than that of aluminum alloys. The most commonly used ones are spot welding and butt welding. Butt welding is generally done by resistance AC butt welding machine. For spot welding, spot welding of thin copper parts is easy, but spot welding of thick parts is difficult.
