Abstract: In this paper, through in-depth analysis and comparison of the existing production process and brazing method of wear-resistant plate of concrete pump vulnerable parts, the problems faced in the actual production of flame brazing, induction brazing and vacuum brazing are analyzed. Combined with the characteristics of continuous atmosphere protection mesh belt furnace and kiln, a continuous atmosphere protection brazing process suitable for large gap, large area and heavy workpiece of concrete pump vulnerable parts is successfully developed, and a complete set of continuous atmosphere protection brazing equipment is independently developed and designed.BCu solder was used to braze the wear-resistant plate of concrete pump wearing parts under continuous atmosphere protection. Through appearance detection, ultrasonic nondestructive flaw detection, microstructure analysis of welded joints, element diffusion and interface behavior analysis, the results show that the self-developed continuous atmosphere protection brazing equipment can quickly and efficiently produce high-quality wear-resistant plate of concrete pump wearing parts. The solder（BCu） has good wettability and spread ability to the wear-resistant lining plate（YG20） and the wear-resistant plate body（Q235B） of the wear-resistant plate. The weld is full and the weld foot is round. The microstructure of the welded joint is dense and uniform, and there are no welding defects such as slag inclusion and porosity, which meets the requirements of industrial products. It can also be applied to the production of wear-resistant and vulnerable parts of engineering machinery such as cutters on the cutter head of shield machinery.
