Description
Technical Field
The utility model relates to a welding part, in particular to a container welding tool.
Background
The composite board development is carried out from the beginning of the 20 th century in China, and is mainly compounded in the modes of explosion welding, explosion welding blank+rolling, cold rolling, hot rolling, ladle casting and rolling, and the like, wherein the heavy steel five factories compound in the mode of ladle casting and rolling; the Shanghai Pudong iron and steel Limited company of Bao Steel group (the original Shanghai third iron and Steel works) is compounded by a direct hot rolling method, but the quality level after molding is relatively higher than that of Japan, a certain gap is still provided, and the composite quality of the plate after Japan is far superior to that of the plate after being compounded by the methods of explosion welding and explosion welding blank+rolling method mainly in China due to the advantages of smaller proportion of unbonded area, higher shear strength of bonding surface, uniform thickness of cladding metal and the like. In the early 20 th century, under the working conditions of high medium corrosiveness and high abrasion degree, surfacing stainless steel is generally adopted in China to meet the working condition requirements, although the surfacing cost is relatively low, the surfacing cost is high, the working period is long, the working strength is high and the like, which are not optimal, so that the development of composite plates is emphasized, the service life of a container can be greatly prolonged, and the development of the composite plates has specific advantages and markets, so that the development of a stainless steel-carbon steel composite material horizontal container preparation process and the development of a device thereof are expected to be developed, and the welding of the composite plates can be completed efficiently and quality-guaranteeing.
Because the base material has dilution effect on the welding seam of the transition layer, the transition zone can have carbon migration process: that is, carbon is transferred from the low-chromium base layer to the high-chromium stainless steel deposited metal, and therefore, a high-hardness carburized layer and a low-hardness decarburized layer are formed at the boundary between the base layer and the clad layer, embrittling (or softening) the fusion zone is caused, the endurance strength is lowered, and fatigue cracks are likely to occur. The welding material of the transition layer is high chromium, nickel steel and other welding materials, so that the generation of martensite structure is avoided, and welding cold cracks are generated. When the 25-13 (E309) austenitic steel welding rod is used for welding the transition layer, in the welding process, if the energy of a welding line is larger than the requirements of process specifications, the dilution rate of a base layer is excessively large, the chromium and nickel content in a molten pool is diluted, when the chromium and nickel content is lower than 18-8, a martensitic structure is formed in the welding metal, and cracks are extremely easy to generate under the action of larger external force.
