Carbon steel tube welding method: electric welding or argon arc welding

Carbon steel tube welding method: electric welding or argon arc welding:

1. Electric welding of carbon steel tube

Carbon steel tube welding is suitable for some simple welding work that does not require high strength and tightness. Due to the simple process and low cost of electric welding, it is widely used in construction sites and maintenance occasions.

The welding methods of carbon steel tubes include manual arc welding, submerged arc welding and gas shielded welding. Among them, manual arc welding is the most commonly used electric welding method. It is easy to operate and has a wide range of applications. However, the welded gap cannot be too small to ensure that the welded position is completely sealed.

2. Argon arc welding of carbon steel tube

Argon arc welding is a high-performance welding method, which has the advantages of strong penetration ability, good weld shape and stable quality. Compared with electric welding, argon arc welding is more complicated, requiring more professional operation skills and more complicated equipment. However, argon arc welding has a wider range of applications and is suitable for occasions that require high strength and tightness, such as petroleum, chemical and other industries.

It should be noted that argon arc welding needs to use argon gas for protection, and the price of argon gas is relatively high, resulting in relatively high cost of argon arc welding.

3. Choose a suitable welding method

To choose a suitable welding method, it needs to be considered comprehensively according to the specific situation. If the welding task is simple and the requirements are not high, electric welding can be used; for high welding quality requirements, high strength and sealing, argon arc welding can be used.

In short, the welding method of carbon steel pipe should be selected according to actual needs, not only the complexity and cost of the welding process, but also the welding effect and safety should be fully considered.

This article introduces two common welding methods for carbon steel tubes. Whether electric welding or argon arc welding is used, it is necessary to pay attention to the operation safety and welding quality to ensure the stability and safety of the welding effect.
