Description

Technical Field

[0001] This utility model relates to the field of pipeline welding technology, specifically a welding device for boiler pipelines. Background Technology

[0002] Boiler pipes are a key component of boiler systems, primarily used for transporting water, steam, flue gas, or other media. They play a crucial role in boiler operation, directly impacting efficiency, safety, and lifespan. Some boiler pipes require welding to achieve suitable lengths. Currently, boiler pipe welding typically involves splicing two pipes together, fixing them in place, and then having a worker use a welding torch to weld around the joint. During welding, usually a portion of the joint is welded first, then the worker manually rotates the pipe to continue welding the remaining joint. This process is quite cumbersome. Therefore, we propose a boiler pipe welding device to solve these problems. Utility Model Content
