A surface treatment process for container welds

Abstract

The invention relates to a weld joint surface treatment process. The process comprises the steps of placing a component to be machined which is obtained after welding at the focal plan position of a laser device; conducting texturing treatment on a weld joint of the component by the adoption of first pulse laser beams, so that a micropore array is generated on the surface of the weld joint of the component to be machined; conducting decontamination and flattening treatment on the weld joint and areas peripheral to the weld joint of the component obtained after the texturing treatment by the adoption of second pulse laser beams, removing an oxidation layer and splashing objects generated in the welding process, and finishing the operation till the surface of the weld joint of the component is smooth; conducting uniform painting treatment on the weld joint of the component obtained after the decontamination and flattening treatment. According to the weld joint surface treatment process, the process is simple, the operation is easy, the greenness and environmental protection are achieved, it is guaranteed that only the weld joint and the peripheral local areas are treated, normal positions are not damaged, the machining is conducted in a noncontact mode, required energy is little, required space is small, generated smoke and dust can be absorbed synchronously, no noise is generated, and pollution to the environment is little.

Description

technical field [0001] The invention relates to the technical field of laser treatment, in particular to a surface treatment process for container weld seams. Background technique [0002] The container is a modular transportation device that has appeared in recent years, and has the characteristics of reusability, high reliability and fast shipment. Since its appearance, it has quickly occupied the freight market and has been widely used in sea and land all over the world. The container system is common all over the world, the size and shape are standard, and the ISO international standard has been formulated, which is applicable to any country. The rapid development of container transportation has led to the prosperity of the container manufacturing industry. The standard dry cargo containers produced in China account for more than 95% of the world's output, and the production and sales volume of containers has remained the first in the world for more than ten years.

Problems solved by technology

Although mechanical grinding can remove the oxide layer and impurities when processing the internal welds of the container, it will produce obvious grinding marks, resulting in uneven grinding surface and affecting the appearance; the precision of grinding during the processing is not conducive to control, and it is easy to damage the surface of the container; it is not conducive to Automation, industrialization and mass production; the operation process will generate a lot of dust, affecting environmental sanitation, and the working environment is harsh; the processing parts have limitations, and some welding seams cannot be cleaned
