Product Description

As a professional solution for internal welding of large steel pipes, this internal welding machine is widely

applicable in scenarios of heavy equipment manufacturing such as power poles, communication poles, and

wind turbine towers. It is specifically designed for internal welding of pipes with a diameter of 400mm or

larger, leveraging advanced technology and precise structure to become a key equipment for industry

automation upgrades. The equipment is equipped with a high-performance gas protection welding system,

using inert gas for full protection, effectively isolating air and moisture, ensuring that the weld seams are

aesthetically pleasing, free of pores, slag, and other defects, with uniform weld penetration and strong

penetration ability. It fully complies with national first-level welding standards and can meet the high-strength

connection requirements of thick-walled steel pipes, achieving stable and controllable welding quality. The

welding speed can be flexibly adjusted within the range of 1–3 meters per minute, suitable for different pipe

diameters and wall thicknesses, ensuring efficient production while precisely controlling welding parameters

and avoiding excessive welding or incomplete penetration issues. For pipe internal operations that are inaccessible

by humans, the equipment is equipped with modularly extendable slot arms, made of high-strength alloys, with

both rigidity and flexibility, which can be adjusted according to the actual pipe diameter requirements, combined

with a precise walking positioning system, to achieve precise tracking and welding of the weld seams. The entire

machine adopts a dust-proof and shock-resistant sturdy structure, suitable for various complex environments such

as factory workshops and outdoor construction, with a simple and intuitive operation interface, facilitating quick

operation by workers, significantly reducing training costs, and providing a welding solution with advanced

technology, stable operation, and convenient operation for large-scale steel pipe manufacturing enterprises.
