Abstract
The invention discloses a composite board welding method, and relates to the technical field of welding. The composite board welding method mainly comprises two steps of preparation before welding and welding. The composite board welding method is reasonable in welding process, guarantees the welding quality of titanium steel composite boards, and satisfies welding requirements.
Description
Technical field
The present invention relates to welding technology field, is more particularly a kind of welding method of composite plate.
Background technology
Titanium steel composite board is basic unit by carbon steel, and industrially pure titanium is cladding, to explode, the ply-metal made of the method such as rolling.The basic unit of titanium steel composite board mainly meets the strength and stiffness requirement of designs for welding structure, and cladding then meets the requirement of the properties such as corrosion resistance.Because basic unit and cladding difference in chemical composition, metallographic structure, physical property etc. is very large, these differences considerably increase welding difficulty.In addition, during titanium steel composite board welding, easily cause cladding titanium plate and basic unit's carbon steel molten phenomenon mutually, the intermediate compound produced is friable tissues, destroys and change original metal lattice, and the two does not have good different-metal material welding.
