Embodiment Construction

[0018] The present invention will be further described below in conjunction with the description and specific embodiments.

[0019] The invention provides a welding process for high-pressure pipes, including the following processes:

[0020] Blanking and scribing: It is forbidden to use needle scribing to make samples and punch holes in the cutting line on the multi-layer surface. Water-soluble markers can be used to mark, and try to avoid scratching the surface of ironware

[0021] Cutting: The thickness of the sample material is 30mm+4mm. When cutting with a CNC plasma cutting machine, the composite layer faces downward, and the cutting starts from the base layer side, and it is strictly forbidden for slag to splash on the surface of the composite layer. processing before cutting

[0022] After cutting, use a planer to plan off the heat-affected zone of the cutting. The groove is also processed by a planer, and the processed groove must be inspected for appearance, and the...

Abstract

The invention relates to the technical field of welding, in particular to a welding process for high-pressure pipes. The invention provides a welding process for high-pressure pipes. By performing welding groove processing on the welded parts of pipe components, the welded parts are tightly spliced ​​before welding, so as to ensure the welding effect in the later stage.

Description

technical field [0001] The invention relates to the field of welding technology, in particular to a welding process for high-pressure pipes. Background technique [0002] Welding is a manufacturing process and technology that uses heat, high temperature or high pressure to join metal or other thermoplastic materials such as plastics. There are many sources of energy for modern welding, including gas flames, electric arcs, lasers, electron beams, friction, and ultrasound. However, the existing welding process usually starts welding after the parts to be welded are fixed for the welding of pipes, and the splicing at the welding port is not precise enough, resulting in poor welding effect. Contents of the invention [0003] Aiming at the defects or deficiencies existing in the prior art, the technical problem to be solved by the present invention is: to provide a welding process for high-pressure pipes, by performing welding groove treatment on the welded part of the pipe pa...
