Embodiment Construction

[0027] A process method for automatic bottoming of a process pipeline robot provided by the present embodiment is specifically as follows:

[0028] 1. Welding equipment and materials

[0029] (1) The welding equipment is a CLOOS welding robot, the model is QRC-410E, which is used in conjunction with the CLOOS welding power source model Qineo Pulse 451 PRO and positioner;

[0030] (2) The base metal of the welding material is Q235B (low alloy steel), the specification is Φ273×10mm, the yield strength>235Mpa, the tensile strength>415MPa; the low alloy steel gas shielded welding wire JQ·MG50- with a wire diameter of Φ1.2mm is used 6.

[0031] 2. Preparation before welding

[0032] (1) Bevel processing: V-shaped bevels are made on Q235B low-alloy steel by lathe processing. The bevel angle is 30° on one side, the blunt edge is 0-1mm, and the gap is 2-3mm. The pipe roundness needs to be corrected during the groove processing. , to ensure that the amount of misalignment is less th...

Abstract

The invention discloses an automatic bottoming process method for a process pipeline robot, relates to the technical field of pipeline welding, ensures that the thickness of a bottoming weld joint is 4-5mm, realizes bottoming welding of a process pipeline by adjusting and controlling a welding position, welding parameters, interlayer temperature and the like, ensures penetration welding and attractive weld joint formation, obtains higher welding quality, and simultaneously ensures the welding quality of the process pipeline. The process is simplified, the welding wire is fully melted under the action of arc heat in the welding process, meanwhile, welding defects caused in the backing weld and operation process can be eliminated, the welding efficiency is improved, the welding cost is reduced, and the deposition efficiency is high.

Description

technical field [0001] The invention relates to the technical field of pipeline welding, in particular to an automatic bottoming process method of a process pipeline robot. Background technique [0002] Most of the process pipelines are seamless steel pipes made of carbon steel, low alloy steel, stainless steel, etc. They are mainly used as raw materials for the manufacture of oil and natural gas pipelines and containers, and are the most commonly used materials for oil and gas pipelines. It has comprehensive properties such as toughness and good weldability, especially in the field of subsea oil and gas pipelines. Robot automatic bottoming process is an efficient welding technology. It can be used in automatic pipeline welding, conventional welding through the powerful function of robot program, characteristics of welding power source and laser ranging and real-time change of welding parameters according to the situation of the group. Usually, argon tungsten arc welding is...
