Abstract

The invention discloses a rust-proof treatment method for a stainless-steel welding joint, and relates to the technical field of rust-proof treatment on the stainless-steel welding joint. According to the rust-proof treatment method for the stainless-steel welding joint, a layer of passivation cream is smeared uniformly on the surface of the stainless-steel welding joint, chemical reaction occurs between the passivation cream and an oxide layer on the surface of the welding joint, when the chemical reaction is finished, the welding joint is washed through a water cannon, and rust-proof treatment on the welding joint of the product is finished. According to the rust-proof treatment method for the stainless-steel welding joint, mechanical treatment is not needed by the welding joint on which passivation treatment is conducted already, the processing difficulty is low, the production efficiency is high, and the rust-proof performance of the welding joint can be improved greatly.

Description

technical field [0001] The invention relates to the technical field of antirust treatment of stainless steel welds, in particular to a method for antirust treatment of stainless steel welds. Background technique [0002] The existing technology is to use mechanical grinding and polishing after the welding of stainless steel materials to rub off the oxide layer on the surface of the weld seam, so that the surface of the weld seam is rubbed bright, and finally apply anti-rust paste on the weld seam to isolate the weld seam from the outside world Exposure to air oxidizes. The disadvantage of this anti-rust treatment method is that the production efficiency of mechanical grinding and polishing is low, and the processing is difficult; the oxide layer on the surface of the weld cannot be completely removed; the appearance is not beautiful after the anti-rust paste is applied, and the weld cannot be completely isolated the effect of oxidation.
