What are the welding methods for geological steel pipes?

To better meet construction requirements, welding may be necessary for geological steel pipes. Incorrect welding techniques can easily lead to poor welds or inaccurate welds, resulting in decreased pipe performance and reduced service life.

To better meet construction requirements, geological steel pipes may need welding. Incorrect welding techniques can easily lead to poor welds or inaccurate welds, resulting in decreased pipe performance and shorter lifespan. Therefore, mastering the correct welding method is essential. Commonly used welding methods include manual welding, metal inert gas welding (MIG), inert gas welding, tungsten inert gas welding (TIG), high-frequency welding, and more. This article provides a detailed introduction to these welding methods.

　　1. Manual Welding: The length of the arc depends on the size of the gap between the welding rod and the geological steel pipe and is adjusted manually. The welding rod also serves as the filler material for the weld seam, making this a widely used welding method.

　　2. Metal Inert Gas Welding (MIG): The arc generates stable heat under the shielding gas, melting the pipe under its own arc. This welding method has good versatility and is therefore widely used.

　　3. Inert Gas Welding: An arc is generated between the refractory tungsten electrode and the pipe.

　　4. Tungsten Inert Gas Welding (TIG): This welding method has good adaptability, high welding quality, and good penetration, but the welding speed is not high.

　　5. High-Frequency Welding: It has low power consumption and can achieve high welding speeds for steel pipes of different materials and wall thicknesses.

　　The welding methods for geological steel pipes are mainly as described above. Each welding method has its unique characteristics and applicable fields. Therefore, the appropriate welding method should be selected based on the usage environment and pipe properties.
