Research and development of construction process for controlling composite board welding cracks

Abstract

The invention discloses research and development of a construction process for controlling composite board welding cracks, and relates to the technical field of composite board welding crack construction processes. The research and development of the construction process comprises the steps of welding raw material inspection, welding process evaluation selection, welding process card writing, welding personnel, welding material and machine tool inspection, stainless steel composite board blanking, welding, ray inspection, construction condition and finished product protection. According to thewelding process evaluation selection, the material and specification of stainless steel composite boards on site are counted, and proper welding process evaluation is selected; and according to welding process card writing, a welding process card suitable for on-site construction is wrote according to the welding process evaluation. The research and development of the construction process for controlling the composite board welding cracks has the advantages that the cracks can be effectively prevented, the welding quality is improved, safe and reliable operation of equipment is guaranteed, the service life of the equipment is prolonged, and reference is provided for companies to better control welding defects in similar engineering construction in the future, and the problem that the cracks are generated in composite board welding is solved.

Description

technical field [0001] The invention relates to the technical field of construction technology for welding cracks in composite plates, in particular to the research and development of a construction process for controlling welding cracks in composite plates. Background technique [0002] With the rapid development of my country's economy, the demand for energy has increased, and the subsequent energy storage has become more and more important. There are more and more large-scale energy equipment storage tanks. Due to the corrosion characteristics of chemical energy, the storage tanks must use chrome-nickel austen Stainless steel, chromium stainless steel and nickel-based materials, while the cost of stainless steel and nickel-based storage tanks is relatively high. With the production of composite plates, and the forging technology of composite steel plates is becoming more and more perfect, the construction unit chooses composite plates as storage tanks in order to save costs...

Problems solved by technology

[0003] It has become a trend that clad plate steel is widely used as a cheap and safe material. Although the welding process of clad plate is mature, cracks often occur in the welding of clad plate at the construction site, which leads to the decline of project quality. Therefore, it is necessary to study the prevention of clad plate Cracks in welding are of great significance to the company and the country
