What is a parallel sealed welding glove box:

Parallel seam welding glove box is a device used to protect the welding area from welding spatter and arc damage. It is protected internally by inert gas, which can prevent oxidation, hydrogen embrittlement and other problems, and improve welding quality.

The main indicators of parallel sealing and welding glove box are:

The gas atmosphere indicators of parallel seam welding glove boxes mainly include oxygen concentration, carbon dioxide concentration, ammonia concentration, etc. Reasonable control of these indicators can ensure the protective effect of gas during the welding process, while avoiding welding quality problems caused by improper gas composition.

1. Oxygen concentration: Oxygen concentration is an important factor affecting welding quality. Excessive oxygen concentration can lead to welding oxidation and reduce welding quality. Therefore, the oxygen concentration should be controlled between 19.5% and 21%.

2. Carbon dioxide concentration: The concentration of carbon dioxide has a significant impact on the protective effect of the welding area. Appropriate carbon dioxide concentration can improve the protective effect of welding areas and reduce the risk of hydrogen embrittlement. Generally speaking, the concentration of carbon dioxide should be controlled between 5% and 10%.

3. Nitrogen concentration: Nitrogen can improve the protective effect of the welding area and reduce the risk of hydrogen embrittlement during the welding process. The nitrogen concentration is generally controlled between 78% and 82%.

In summary, the gas atmosphere index of parallel seam welding glove boxes has a significant impact on welding quality and the health of operators. Reasonable concentrations of oxygen, carbon dioxide, and ammonia can ensure welding quality and reduce the risk of hydrogen embrittlement.
