What are welding rods and welding machines used for?

Welding rods and welding machines are indispensable tools in the welding process, and they each play an important role:

Welding rods: Welding rods are mainly divided into the following types:

Structural steel welding rods: mainly used for welding general structural steel.
Molybdenum and chromium-molybdenum heat-resistant steel welding rods: mainly used for welding pearlite heat-resistant steel.
Stainless steel welding rods: mainly used for welding stainless steel and heat-resistant steel.
Low-temperature steel welding rods: mainly used for welding various structures working under low temperature conditions.
Overlay welding rods: mainly used to obtain overlay layers with red hardness, wear resistance and corrosion resistance.
Cast iron welding rods: mainly used for repairing cast iron parts.
Nickel and nickel alloy welding rods: mainly used for welding nickel and its alloys, sometimes also used for overlay welding, welding cast iron, dissimilar steel welding, etc.
Copper and copper alloy welding rods: mainly used for welding copper and copper alloys, dissimilar steel, cast iron, etc.
Aluminum and aluminum alloy welding rods: mainly used for welding aluminum and aluminum alloys.
Special purpose welding rods: welding rods designed according to special needs.
Welding machine: Welding machine is a device for welding operation. It controls the size and time of the current to generate high temperature between the welding rod and the workpiece, thereby achieving metal fusion. Welding machines can be divided into AC welding machines, DC welding machines and pulse welding machines. Different welding machines are suitable for different welding materials and welding processes.

In summary, welding rods and welding machines play a vital role in industrial production. Together, they ensure welding quality and efficiency.
