Problems solved by technology
Because the physical properties, thermal conductivity and specific heat capacity of the wear-resistant composite plate and the mud pipe are different, in the prior art, when the wear-resistant composite plate and the wall of the mud pipe are welded, it is difficult to ensure the welding quality, which makes the wear-resistant composite Mud pipe falls off or shifts
Especially when the wear-resistant composite plate is installed on two mutually perpendicular pipe walls, it is difficult to weld, which is not conducive to welding work

Abstract
The invention discloses a dredger wear-resistant composite board welding method. The dredger wear-resistant composite board welding method comprises the following steps that S10, a mud pipe and two wear-resistant composite boards are provided, and the mud pipe comprises two pipe walls; S20, cutting slopes are formed in one ends of the two wear-resistant composite boards correspondingly, and plug welding holes are formed in the pipe walls; S30, the two wear-resistant composite boards are attached to the inner side walls of the two pipe walls correspondingly, the ends, provided with the cutting slopes, of the two wear-resistant composite boards are spaced, and a groove is formed; and S40, the wear-resisting composite boards and the pipe walls are welded and fixed in the plug welding holes, then a base layer welding bead, a transition layer welding bead and a wear-resisting layer welding bead are sequentially welded in the groove, the transition layer welding bead is located in the wear-resisting layer welding bead and the base layer welding bead, a welding wire model of the base layer welding bead is GB / T10045E501T-1, and a welding wire model of the transition layer welding bead is GB / T17853E309LT1-1. Welding is convenient, and the welding quality is good.
Description
technical field [0001] The invention relates to the technical field of ships, in particular to a welding method for a wear-resistant composite plate of a dredger. Background technique [0002] The mud pipe of a dredger is a pipe used to transport sediment. During the process of conveying mud and sand, the inner wall of the pipe is greatly worn by the sand. Therefore, during the construction of the dredger, the inner wall of the mud pipe is usually Wear-resistant composite plates are welded to prolong the service life of the mud pipe. Because the physical properties, thermal conductivity and specific heat capacity of the wear-resistant composite plate and the mud pipe are different, in the prior art, when the wear-resistant composite plate and the wall of the mud pipe are welded, it is difficult to ensure the welding quality, which makes the wear-resistant composite The mud pipe is detached or displaced. Especially when the wear-resistant composite plate is installed on two...
