Continuous Inner Bore Cladding of Long Pipes

In the inner bore cladding of long pipe workpieces, extended welding distances, confined spaces, and continuous operating conditions place higher demands on welding stability and weld layer consistency. Especially for inner bore cladding of pipes with lengths of 6 meters and above, conventional equipment often faces challenges in arc stability, wire feeding uniformity, and weld bead formation. To address these typical application requirements, this hot wire TIG dual-tungsten electrode cladding equipment is structurally and technologically designed for long-distance, continuous inner bore cladding operations, with a focus on improving welding stability in long pipe applications.

By combining hot wire TIG technology with a dual-tungsten electrode welding process, the equipment maintains stable arc performance and continuous wire feeding during long-distance inner bore cladding, resulting in smoother and more uniform weld layer formation. Through automated control, precise matching of welding parameters and continuous process operation are achieved, reducing the influence of manual intervention on weld quality and ensuring higher consistency and repeatability during actual operation. At the same time, the equipment meets the requirements of continuous inner bore cladding while maintaining weld quality, making it suitable for batch production conditions.

In practical applications, the equipment has been stably used for wear-resistant and corrosion-resistant cladding on the inner surfaces of various long pipe components, demonstrating reliable operation and consistent welding results. Looking ahead, Xushen will continue to advance equipment design and welding process optimization to meet the demands of complex operating conditions in long pipe inner bore cladding.
