Abstract

The invention provides a weld joint machining technology and mechanical equipment with weld joints and relates to the field of machining. The weld joint machining technology mainly comprises the steps that the weld joints are ground, and the surface roughness of the ground weld joints ranges from 0.01 micrometer to 0.4 micrometer. By the adoption of the weld joint machining technology, residual contaminants, such as food, medicine, bacteria or other impurities, on the weld joints are easily cleaned, the surfaces of the weld joints are quite smooth due to the small roughness, and the cleaning is quite convenient; and meanwhile, the smaller the surface roughness is, the smaller the surface tension is, and the attachment probability of the contaminants is reduced greatly. The invention further provides the mechanical equipment with the weld joints, where the weld joints are machined and formed mainly through the weld joint welding technology. By the adoption of the weld joint machining technology and the mechanical equipment, the surface roughness of the weld joints in different positions of the mechanical equipment with the weld joints can be controlled effectively, the use safety of the mechanical equipment with the weld joints is improved, and the sanitary safety of production products is improved.

Description

technical field [0001] The invention relates to the field of mechanical processing, in particular to a weld seam processing technology and mechanical equipment with weld seam. Background technique [0002] With the development of society, people's requirements for the hygiene and safety of food and medicine are constantly improving, so higher requirements are put forward for the production equipment of food and medicine. Welds are ubiquitous in production equipment, and improper surface treatment of welds makes it easy to leave a large amount of food, medicine, germs and other pollutants on the surface of welds, and it is difficult to clean up pollutants due to inadequate surface treatment of welds. The sanitation of production equipment cannot be guaranteed, resulting in the sanitation and safety of the food and medicine it produces cannot be guaranteed. Contents of the invention [0003] The purpose of the present invention is to provide a welding seam processing techno...
