Abstract

The invention discloses a surface treatment method for an enclosure of an intermediate frequency spot-welder resisting high-temperature splash. The method comprises the following steps: (1) putting the enclosure of the intermediate frequency spot-welder after deoiling and pollution cleaning treatment in a vacuum room, and preparing a silicon nitride film on the surface of the enclosure by means ofa chemical vapor deposition method by taking silicon tetrachloride and ammonia gas as raw materials; and (2) then brushing two high-temperature-resistant coatings to the surface of the enclosure. Thesurface treatment method for the enclosure of the intermediate frequency spot-welder resisting high-temperature splash is simple to operate, and the prepare enclosure has excellent wear resistance onthe surface, is ageing resistant and great in film hardness, and in particular has short-time high-temperature resistance, and the surface paint film can be prevented from being burned by splash dripping to the surface effectively, so that the enclosure is protected effectively.

Description

technical field [0001] The invention belongs to the technical field of intermediate frequency spot welding machine preparation, and in particular relates to a method for treating the surface of an intermediate frequency spot welding machine casing resistant to high temperature spatter. Background technique [0002] The intermediate frequency spot welding machine is a new type of resistance welding machine, and it is also the latest type of intermediate frequency spot welding machine. It is controlled by a touch screen. The display can display the welding current of each welding, and can display faults and error warnings in time. Compared with ordinary AC resistance welding machines, it has the following advantages: (1) Energy saving: compared with the use of low frequency, it can reduce the consumption of electric energy, and the transformer with the same weight can output more energy, and can be conveniently used with large automatic welding guns; ( 2) In the semi-automatic...
