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.

Butt welding of nickel-based alloys
Nickel-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.

Butt welding of copper and copper alloys
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.

Flash butt welding of wire rods
Wire rods include low carbon steel wire rods, medium and high carbon steel wire rods. It is an economical and efficient steel material with high tensile strength and yield strength, good plasticity, and low relaxation performance. It is mainly used as a blank for wire drawing and is also widely used in the construction of cement products, bridges, nuclear power plants, high-rise long-span buildings, highways, etc.

Flash butt welding of low carbon steel and medium carbon steel
Low carbon steel has high resistivity. When melted at high temperature, carbon elements produce protective atmospheres of CO and CO2 and do not produce high melting point oxides. Therefore, the weldability is good. Medium carbon steel has higher carbon content than low carbon steel, has higher resistivity, crystallization interval, high temperature strength and is easy to harden. It is necessary to increase the upsetting force and upsetting allowance

Flash butt welding of alloy steel
The content of each element in alloy steel is different. Their physical and chemical properties are also different, and the weldability is naturally different. When using flash butt welding machine welding, the following process measures should be paid attention to:
