Abstract

The invention relates to an intelligent braze coating device and a braze coating method. The intelligent braze coating device comprises a movable workbench, a wire feeding mechanism, two industrial robots, a coating temperature field monitoring device, a coating contour monitoring device, a high-energy beam generator and a control system, wherein the two industrial robots, the coating temperaturefield monitoring device and the coating contour monitoring device are all arranged above the movable workbench, one of the two industrial robots is used for providing wire brazing filler metal, the other one of the two industrial robots is used for providing a braze coating heat source, the wire feeding mechanism is used for conveying wire-shaped or tubular brazing filler metal to the robots, anda high-energy beam emitter provides a heat source for the robots through a high-energy beam emitting head. A prepared coating is a cladding layer which is smooth in surface, good in combination with base metal, free of crack defects and compact in structure. From the perspective of equipment platform development, the problems that manual braze coating is poor in stability and uneven in coating thickness are solved.

Description

technical field [0001] The invention relates to the field of welding technology, in particular to an intelligent brazing device and a brazing method. Background technique [0002] Brazing is essentially a special kind of brazing, which relies on the molten solder or the liquid phase formed by the diffusion between the surface of the base metal and the solder, spreads the base metal under capillary action, and interacts. Coating preparation means. The prepared coating has the advantages of high bonding strength, small thermal stress, smooth surface and high precision. Traditional brazing methods such as induction brazing and furnace brazing require a lot of manual operations. At the same time, during the coating preparation process, there is a lack of monitoring of coating morphology and temperature field, and the quality of the obtained coating needs to be improved. Therefore, the research and development of intelligent brazing equipment, especially the real-time monitorin...
