Problems solved by technology

[0003] However, in the production process of the stainless steel cladding of the special material treatment pool of a nuclear power project, ordinary manual argon tungsten arc welding generally adopts multi-layer and multi-pass welding (such as figure 1 As shown), the welding efficiency is low, the production cost is high, and multiple heat inputs are likely to cause large deformation of the base metal
Manual argon tungsten arc welding requires high skill levels of welders, and is highly dependent on highly skilled welders. The welding quality is unstable, the welding efficiency is low, and the labor intensity is high. It is difficult to meet the needs of on-site construction.

Abstract

The invention provides efficient tailor-welding equipment and method for a steel clad plate of a nuclear power stainless water tank. The efficient tailor-welding equipment comprises a feeding conveyorused for feeding and conveying the steel clad plate to be welded, wherein a tailor-welding tool used for welding plates is arranged at the tail end of the feeding conveyor, and the other side of thetailor-welding tool is in butt joint with a discharging conveyor. The welding tool comprises a welding machine walking track, wherein a welding machine used for welding is installed on the welding machine walking track slidably, a welding gun assembly is installed at the head of the welding machine, and an automatic wire feeder used for wire feeding is installed at the top of the welding machine.The efficient tailor-welding equipment further comprises a control box for controlling the whole equipment. The efficient tailor-welding equipment uses a plasma arc welding machine for stainless steelclad splicing operation and can meet the requirement for manufacturing stainless steel clad splicing in a workshop, thereby improving the welding efficiency and reducing the construction cost.

Description

technical field [0001] The invention belongs to the technical field of nuclear power facility welding, and in particular relates to high-efficiency tailor welding equipment and a method for nuclear power stainless pool steel cladding panels. Background technique [0002] At present, in the construction of domestic nuclear power plants and nuclear facilities, there are a large number of splicing welds on the cladding of stainless steel pools. Taking a nuclear power project as an example, the total length of splicing welds on the stainless steel cladding of the first phase project is about 70,000m, and the material of the cladding panels is 06Cr18Ni11Ti austenitic stainless steel , the thickness is 3mm, and the stitching welds are long straight butt welds. In the previous nuclear power projects, manual tungsten argon arc welding was mainly used for stainless steel cladding welding. Its welding process performance is good, the arc is open, and the arc and molten pool can be obs...
