Abstract

The invention discloses a method for connecting two connecting pipes, which is used to connect a first connecting pipe and a second connecting pipe. Place a sleeve sleeve at the alignment of the butt end of the first connecting pipe and the butt end of the second connecting pipe and fix it; secondly, use a welding mold to connect the first connecting pipe and the second connecting pipe at both ends of the sleeve and the sleeve. The connecting pipes are welded; finally, the welding mold is removed. In the present invention, the sleeve and the first connecting pipe and the second connecting pipe at both ends of the sleeve are placed in the cavity of the welding mold in advance, and the thermite in the fuel hopper is ignited by gunpowder to form a melt and melt away The aluminum gasket is finally flowed into and molded in the cavity, so that the sleeve pre-set in the cavity and the first connecting pipe and the second connecting pipe at both ends of the sleeve are covered and formed into a cladding layer. The method is simple , Convenient, short welding time and good welding effect.

Description

technical field [0001] The invention relates to a connecting method of two connecting pipes. Background technique [0002] In the field of wind power, it is necessary to carry out butt welding of two tubular busbars vertically on the wind power tower. Due to the limited space in the wind power tower and the welding of tubular busbars needs to be seamless around, the welding operation is difficult and takes a long time. [0003] Therefore, there is an urgent need for a simple and easy welding method. Contents of the invention [0004] The main purpose of the present invention is to overcome the shortcomings of the prior art and provide a simple method for connecting two connecting pipes. [0005] In order to achieve the above object, the method for connecting two connecting pipes provided by the present invention is used to connect the first connecting pipe and the second connecting pipe, comprising the following steps: [0006] First, align the butt end of the first conn...
