Explanation

A type of arc welding. The method of weld with the arc formed between the carbon rod or graphite rod and the workpiece as the heat source. The power source is DC arc welding generator or arc welding rectifier, which adopts DC positive connection. When weld, filler metal can be added or not added as required. It can be used for weld steel, cast iron, nonferrous metals, etc. It can also be used for surface overlaying. Due to poor protection effect, it is only applicable to occasions with less strict requirements, such as weld of general low-carbon steel vessels. Bipolar carbon arc welding is a form of variation. In a bipolar arc welding gun, the arc is formed between two carbon rods, and the workpiece is not part of the circuit. carbon are welding can be used for overlaying and soldering, but it is mainly used for overlaying and repair work. Usually, a small current is used, as long as it can ensure the free flow of the filler metal on the workpiece
