Problems solved by technology

[0002] As a relatively common production process in the mechanical field, welding is frequently used in the manufacturing process of products. Welding products are usually metals, and metals are prone to rust spots at the welds. Even after the surface is sprayed later, because the surface of the welds is uneven Uneven, poor spraying effect, rust spots still exist, and will affect welding fastness over time

Embodiment Construction

[0013] A welding process that can reduce rust spots at the weld seam, the steps are as follows:

[0014] A. Degrease the surface of the two parts that need to be welded; the degreasing method can be to place the parts in a cylinder with degreasing agent for 10 minutes;

[0015] B. Put the two parts after degreasing into the hydrochloric acid solution with a concentration between 5% and 15% for pickling to remove the surface oxide layer, and the duration is 15 minutes;

[0016] C. Put the two parts after pickling into the alkaline liquid to neutralize the hydrochloric acid solution remaining on the surface to prevent secondary oxidation, and the duration is 15 minutes;

[0017] D, Take out the two parts and put them in a dry environment, wait for the water to fully evaporate and dry before welding.

[0018] Wherein, the interval between step B and step C cannot exceed 5 minutes. If the time is too long, the hydrochloric acid solution attached to the surface of the parts will ...

Abstract

The invention discloses a welding process capable of reducing welding seam rusts. The process comprises the following steps of de-oiling the surfaces of two parts required to be welded; placing the two de-oiled parts to be subjected to acid washing in a hydrochloric acid solution with the concentration of between 5 percent and 15 percent to remove an oxidation layer on the surface, wherein the lasting time is 15 minutes; placing the two parts subjected to acid washing in an alkaline solution to neutralize the hydrochloric acid solution left on the surface and prevent secondary oxidation, wherein the lasting time is 15 minutes; taking the two parts out, placing the parts in a dry environment, and after water is fully evaporated and aired, welding the parts. The rusts at a welding place of a metal product can be effectively reduced, and the welding firmness of the metal product is improved.

Description

technical field [0001] The invention relates to a welding process capable of reducing rust spots at welding seams. Background technique [0002] As a relatively common production process in the mechanical field, welding is frequently used in the manufacturing process of products. Welding products are usually metals, and metals are prone to rust spots at the welds. Even after the surface is sprayed later, because the surface of the welds is uneven Unevenness, poor spraying effect, and rust spots still exist, which will affect the welding fastness over time. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a welding process capable of reducing rust spots at the weld seam, which can effectively reduce the rust spots of metal products at the weld and improve the welding fastness of the metal products. [0004] The technical scheme of the present invention is: a kind of welding process that can reduce the rust spots a...
