Abstract

The invention discloses an electric-arc scale-welding fine welding device for a steel tube. The electric-arc scale-welding fine welding device is characterized by structurally comprising an external framework, a control display screen and the like. The electric-arc scale-welding fine welding device has the beneficial effects that: in order to solve the problems that scale-welding is mostly accomplished manually as a metal oxide exists on the surface of the original welding seam, welding seam loading is difficult, a welding finished product welding seam is not flat, and a manual operation errorrate is high while the electric-arc scale-welding fine welding device for the steel tube in the prior art is used, a welding seam outer surface processing mechanism, a scale-welding welding line done-welding mechanism, a steel tube clamping retarding mechanism and a scale-welding welding tank forming mechanism are designed; in use, the welding seam outer surface processing mechanism performs oxide-removal grinding treatment on the surface of the welding seam, and is matched with the scale-welding welding tank forming mechanism to define a welding tank; and finally, the steel tube clamping retarding mechanism is matched with the scale-welding welding line done-welding mechanism to accomplish scale-welding fine welding treatment, so that welding seam oxides are cleared, the welding seam isgrinded flatly, mechanical automatic scale-welding welding line operation is precisely positioned, and the pre-loading effect of a welding flux tank is achieved.

Description

technical field

[0001] The invention relates to the technical field of fish scale welding, in particular to an arc fish scale welding fine welding device for steel pipes. Background technique

[0002] Arc welding refers to the use of arc as a heat source and the physical phenomenon of air discharge to convert electrical energy into thermal energy and mechanical energy required for welding, so as to achieve the purpose of connecting metals. The main methods are electrode arc welding, submerged arc welding, and gas shielded welding. etc. It is currently the most widely used and most important fusion welding method, accounting for more than 60% of the total welding production. In arc welding, there is a welding technology called fish scale welding. Fish scale welding can penetrate the solder, effectively remove solder impurities, and obtain welded steel parts with higher strength. It is suitable for more cutting-edge technological fields. With the rapid development of science a...
