Problems solved by technology

The labor intensity of manual grinding workers is high and the efficiency is low; the flame cutting method uses oxygen burning to remove slag, because the flash welding slag contains a lot of metal oxides, this method will lead to an increase in the weld defect rate, and the weld surface quality after slag removal is relatively poor Poor, it is difficult to ensure the quality of the weld seam

Abstract

The invention relates to a pipeline flash butt welding rotation mechanical internal slag removing system. The pipeline flash butt welding rotation mechanical internal slag removing system mainly comprises a pushing mechanism, a hydraulic power system and a slag removing knife set; the slag removing knife set is driven by the hydraulic power system to rotate and is driven by the pushing mechanism to move inside a pipeline, and therefore removing of slag in welding lines of the inner wall of the pipeline can be achieved. The pipeline flash butt welding rotation mechanical internal slag removing system is compact in structure and low in manufacturing cost, and the complete machine miniaturization is easily achieved; the pipeline flash butt welding rotation mechanical internal slag removing system is used in cooperation with a pipeline flash butt welding device, the slag in the welding lines of the inner wall of the pipeline can be removed, the slag removing efficiency is high, and the quality of the surfaces of the welding lines is good; and the pipeline flash butt welding rotation mechanical internal slag removing system is high in adaptive capacity, can be suitable for inner wall slag removing of the welding lines of the metal pipeline with the nominal diameter being 219 mm and the wall thickness ranging from 8 mm to 20 mm.

Description

technical field [0001] The invention relates to the technical field of slag cleaning equipment for pipeline flash butt welding, in particular to a pipeline flash butt welding rotary mechanical internal slag cleaning system. Background technique [0002] Flash butt welding is an advanced welding method, the welding process parameters are easy to control and adjust, the process is stable, and the joint quality is good. Compared with the traditional welding method, it has the following advantages: ①It belongs to solid phase welding, there is no molten pool, and the welding quality ② No need to add deposited metal, the chemical composition of the welded joint is the same as that of the base metal; ③ No need for gas protection or slag protection, eliminating the source of pollution; ④ High degree of automation, not relying on manual welding skills; ⑤ Short welding cycle and high welding efficiency. [0003] Although the flash welding technology has many advantages, there is a ver...
