AI Technical Summary
Traditional gas pipeline welding clamping devices are prone to causing pipeline shaking and displacement during the welding process, affecting welding accuracy and resulting in misaligned and uneven welds.
Design a clamping device for welding gas pipelines, including a reinforcement mechanism and an auxiliary support mechanism. The device expands the support range and enhances the grip through hydraulic and pneumatic systems, and provides additional support through an arc-shaped bracket to prevent the center of gravity from shifting and swaying.
It effectively prevents pipe shaking and center of gravity shift during welding, improves welding quality, enhances the applicability and versatility of the device, and reduces construction costs.
