AI Technical Summary

Technical Problem

During pipeline welding, existing argon arc welding technology struggles to achieve uniform argon gas protection, especially since the curvature of the pipeline makes it difficult for argon gas to be released evenly, thus affecting the welding effect.

Method used

A variable pipeline welding front argon purging protection device was designed, including a device housing, an argon arc gun sleeve, an argon gas pipe, and a stainless steel mesh. The argon gas pipe outputs a stable argon gas flow, and the stainless steel mesh achieves gas flow uniformity, adapting to pipeline welding of different diameters.

Benefits of technology

It achieves uniform and stable argon gas output during pipeline welding, provides effective protection, adapts to welding requirements of different pipe diameters, and improves welding quality.
