Embodiment Construction

[0023] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0024] like Figure 1 to Figure 3 As shown, a kind of plate laser surfacing welding process of the present invention, this process comprises the following steps:

[0025] S1: According to the shape of the welding part of the plate to be welded, select the connecting plate of the corresponding shape, and splice the two plates and the connecting plate together; the connecting plate enters the groove between the plate and the connecting plate when the plates are welded The welding liquid is collected, the welding liquid first fixes the connecting plate and the plate together, and the subsequent welding liquid enters the groove to weld the two plates, avoiding the leakage of the welding liquid, and at the same time making the welding of the plates mor...

Abstract

The invention belongs to the technical field of plate laser overlaying welding technology and particularly provides a plate laser overlaying welding technology. The plate laser overlaying welding technology comprises the following steps that a connection plate in a corresponding shape is selected according to different shapes of welded portions of two plates to be welded, and the two plates and the connection plates are spliced together; welding flux is placed in a shell of a high-precision laser overlaying welding device, the high-precision laser overlaying welding device is made to move in agroove constituted by the two plates and the connection plate, the welding flux is molten by the high-precision laser overlaying welding device and discharged into the groove for welding the two plates; a displacement sensor of the high-precision laser overlaying welding device senses whether the lower end of the shell deflects towards one plate or not, a controller of the high-precision laser overlaying welding device processes the information sensed by the displacement sensor, and the controller controls the lower end of the shell to be always between the two plates; the shell and heat conducting rods of the high-precision laser overlaying welding device conduct heat in welding fluid to the welding flux, and ultrasonic emitters emit ultrasonic waves to drive the heat conducting rods toshake.

Description

technical field [0001] The invention belongs to the technical field of laser welding technology, in particular to a laser surfacing welding technology for plates. Background technique [0002] In industrial production, it is sometimes necessary to weld the plates. When the traditional welding process welds the plates, the quality of the welding is not good, which can no longer meet the increasingly high quality requirements of the current society; the laser surfacing process has become the current better The process of welding plates. Laser overlay welding is a method used in industrial workpiece processing. In conventional laser overlay welding, the surface of the workpiece or substrate is melted with the aid of a laser beam and the molten pool thus formed is supplied with powdered material. . The powder fed into the molten bath is likewise melted, so that after the solidification of the molten powder material and the workpiece surface, a material bonded, in particular fu...
