U-shaped rib inner side welding seam repairing system

Abstract

The invention relates to a U-shaped rib inner side welding seam repairing system which comprises a repairing trolley arranged in a machining space formed by a U-shaped rib and a bottom plate and capable of moving in the length direction of the U-shaped rib. The first repair mechanism is arranged at the front end of the repair vehicle; the second repair mechanism and the first repair mechanism are arranged on the repair trolley side by side, and the second repair mechanism is used for planing and grinding the welded junction and performing repair welding on the welded junction; the monitoring mechanism is used for acquiring working parameters of the first repair mechanism and the second repair mechanism; and the controller is in signal connection with the repair car, the first repair mechanism and the second repair mechanism, and the controller adjusts the working states of the repair car, the first repair mechanism and the second repair mechanism according to the working parameters obtained by the monitoring mechanism. Thus, the controller controls the first repair mechanism to clean the weld beading of the weld joint on the inner side of the U-shaped rib, and then controls the second repair mechanism to perform polishing and repair welding, so that the welding quality of repair is improved.

Description

technical field [0001] The present disclosure relates to the technical field of U-shaped rib welding, and in particular, to a system for repairing inner welds of U-shaped ribs. Background technique [0002] In recent years, people have higher and higher requirements for the welding quality of U-shaped rib fillet welds, gradually developing from single-sided groove partial penetration fillet welds to double-sided welding full penetration fillet welds. The inner fillet weld of the U-shaped rib fillet weld is welded in a narrow space and is welded with special equipment. Due to the limited space, manual operation cannot be performed, and it is difficult to repair the inner fillet weld once a defect occurs during the welding process. The conventional method is to plan the weld from the outside of the U-shaped rib for repair welding. When the welding defect is located in the inner fillet weld of the U-shaped rib, if the welding needs to be deeply planed from the outside, it is e...

Problems solved by technology

[0004] The purpose of this disclosure is to provide a U-shaped rib inner weld rework system, which is used to solve the problem of rework welding on the inner side of U-shaped ribs in the related art, and improve the welding quality of U-shaped rib fillet welds. At the same time, it solves the problem that there are weld bumps on the U-shaped rib welding bottom plate, which leads to the low quality of the weld repair system on the inner weld seam.
