Title:
TC4 TITANIUM ALLOY SUBMERGED ARC WELDING FLUX, A PREPARATION METHOD THEREFOR AND APPLICATION THEREOF
Document Type and Number:
WIPO Patent Application WO/2023/134149
Kind Code:
A1
Abstract:
A TC4 titanium alloy submerged arc welding flux, prepared from an adhesive and powder, wherein the powder is formed by mixing, by mass fraction, 4.5% to 5.5% of BaCl2, 1.8% to 2.1% of LiF, 4.8% to 5.1% of NaF, and the remainder being CAF2. The preparation method for the TC4 titanium alloy submerged arc welding flux comprises: mixing and dry-stirring raw material powder according to a powder proportion, then adding an adhesive and continue stirring to obtain a mixture; and drying the obtained mixture at a low temperature, then sintering same at a high temperature, cooling same to room temperature, and sieving same to obtain the TC4 titanium alloy submerged arc welding flux. According to the welding flux, the proportion of each component of the welding flux is set, the viscosity, surface tension and fluidity of molten slag are optimized, and when the welding flux is used in conjunction with a TC4 titanium alloy submerged arc welding wire for submerged arc welding, good welding process performance and mechanical performance are achieved. The present invention also relates to an application of the submerged arc welding flux.
