The difference between welding torch and cutting torch

The difference between welding torch and cutting torch:

Welding torch, also known as welding torch, is a tool for welding or preheating ferrous or non-ferrous metal workpieces using oxygen and medium and low pressure acetylene as heat sources. It is the main tool for gas welding operation. The function of the welding torch is to mix the combustible gas and oxygen evenly in a certain proportion, and spray it out from the welding nozzle at a certain speed to form a flame with a certain energy rate, a certain composition, suitable for welding requirements and stable combustion. The quality of the welding torch directly affects the welding quality of gas welding. Therefore, the welding torch is required to have a good performance in adjusting the ratio of oxygen to combustible gas and the flame energy rate, so that the speed of the mixed gas injection is equal to or greater than the combustion speed, so that the flame is stable. burning. At the same time, it is also required that the weight of the welding torch should be light, and it should be easy to operate, safe and reliable during use.

The function of the cutting torch is to mix oxygen and acetylene in proportion to form a preheating flame, and spray high-pressure pure oxygen onto the workpiece to be cut, so that the metal to be cut is burned in the oxygen jet, and the oxygen jet flows the molten gas generated by combustion. The slag (oxide) is blown away to form a slot. The cutting torch is the main tool for gas cutting the workpiece.
