Abstract

The invention discloses a pipeline welding robot for field construction welding of special steel. The pipeline welding robot comprises two welding vehicles, two auxiliary vehicles, an intelligent monitoring unit and a power supply unit, wherein the welding vehicles are execution units for finishing the welding task; the auxiliary vehicles are used for finishing the welding task at earlier stage and the treatment task at later stage; the intelligent monitoring unit is responsible for monitoring and controlling the welding vehicles and the auxiliary vehicles and realizing visual tracking and artificial intervention of the welding operation; the power supply unit is used for providing a work power supply of the welding process; the two welding vehicles and the two auxiliary vehicles are distributed at the outer side of the pipeline at intervals; each welding vehicle and each auxiliary vehicle which are adjacent to each other are connected through an elastic restraining unit; the intelligent monitoring unit is respectively connected with each welding vehicle and each auxiliary vehicle through transmission cables. The pipeline welding robot disclosed by the invention has the advantages that the welding time is shortened, the efficiency is increased, the constant-temperature preheating before welding and constant-temperature tempering after welding are realized for the special steel, the welding quality is high and the artificial intervention is realized during welding operation. The pipeline welding robot is suitable for field welding operation.

Description

technical field [0001] The invention relates to a pipeline welding robot, in particular to a pipeline welding robot used for field construction welding of special steel materials. Background technique [0002] P91 steel is a new type of martensitic heat-resistant steel developed in the late 1970s and early 1980s in the United States. As an improved 9Cr-1MoV steel, it has high temperature strength, good oxidation resistance and creep resistance, and relatively With the characteristics of high thermal conductivity and low thermal expansion rate, it has become the most critical component steel for a large number of newly-built supercritical units and ultra-supercritical unit boilers. For example, in the construction of many large-scale thermal power plant units in recent years, the main steam pipeline P91 steel is used. P91 steel fills the gap between ferritic steel and austenitic steel. Its weldment has a smaller cross-sectional size, which effectively reduces the wall thickn...
