Auto Rotary Inner Boring Welder      Portable Line Machine Welder 110V

The inner hole welding machine is a piece of special equipment for repairing metal internal hole defects and is mainly used for welding repair and cladding treatment on the circular inner walls of valves, valve bodies and various castings. The inner hole welding machine has the advantages of no deformation, no pores and repair layer hardness adjustability, is free of manual intervention for operation and is high in degree of automation. This welding machine adopts a continuous automatic feeding mode to evenly attach welding wires to workpieces and is suitable for surface overlaying of pipeline inner holes, pipeline outer diameters and transmission shafts. The wire diameter of the welding wire is 1.0mm. The inner hole welding machine is widely applied to metal parts that require inner hole repair, such as valves, pipelines and transmission shafts.

It has many advantages of being small in size, light in weight, easy to carry, good in welding quality and low in requirement for the environment and the used space. It is widely used in large-scale equipment and pin-hole construction machinery and used for the bearing bore welding repair and short-distance longitudinal seam welding. In short, the portable automatic bore welding machine is an essential tool for the mining industry and the project site maintenance.

1. High efficiency: The inner hole welding machine can achieve continuous welding, so that the welding efficiency is greatly improved, and the time cost and the labor intensity of manual welding are reduced.

2. High quality: The welding parameters and the welding quality can be controlled in the welding process to ensure that the strength and the sealing performance of the welded joint meet the requirements.

3. Flexibility: The machine is suitable for welding needs of deep holes with different materials, hole diameters and shapes and has high adaptability and flexibility. The welding machine can be used in combination with a boring machine, and this combination can efficiently complete the repair work especially when repairing large equipment such as shield tunneling machines and mining equipment.

4. Portability: Small size, light weight, adapt to various working scenarios.
