The working principle of gas welding hose is to use the pressure and flow characteristics of gas to transport gas, thereby providing protective gas during the welding process.

Specifically, gas welding hoses are usually made of multiple layers of rubber or plastic materials, where the inner layer is used to transmit gas, the middle layer enhances the strength and pressure resistance of the material, and the outer layer is used to protect the inner layer material. When the gas pressure increases, the inner material of the hose is squeezed, but the structure of the hose can withstand this pressure and ensure that the gas does not leak. At the same time, the elasticity of the hose can also absorb and buffer the vibration and impact during gas transportation.

The main functions of welded hose are as follows:

Deliver protective gas

Gas welding hoses deliver shielding gases. During the welding process, the protective gas isolates the air, reduces the oxygen concentration, and prevents oxidation of the welding area.

Enhance welding effect

By using flux gas, gas welding hose can improve the fluidity of the molten pool and the quality of the weld during the welding process, and improve the welding effect.

Adjust welding parameters

Different welding processes require different welding parameters. Such as welding current, voltage, welding speed, etc. Adjusting these parameters requires gas welding of the hose. Taking the welding current as an example, by changing the flow of shielding gas in the gas welding hose, the welding current can be adjusted. In order to achieve the purpose of optimizing welding quality.

Protective welding equipment

During the welding process, welding equipment is susceptible to electromagnetic interference. The gas welding hose can effectively shield electromagnetic interference and protect the normal operation of the welding equipment.

The material of gas welding hose has an important impact on its working performance. Generally speaking, gas welding hoses should have excellent heat resistance, corrosion resistance and sufficient strength. For example, PTFE hose has good heat resistance and chemical stability. And it can maintain stable performance in high temperature and corrosive environments.
