Abstract

The invention discloses a mobile phone back cover steel disc spot welding repairing method. The mobile phone back cover steel disc spot welding repairing method comprises the steps that (1) mobile phone back cover spot welding non-performing products are provided; (2) original steel discs are milled from spot welding non-performing positions of the mobile phone back cover spot welding non-performing products in the thickness direction of the mobile phone back cover spot welding non-performing products, and parts with the thickness ranging from 0.05 mm-0.06 mm are continuously milled in the thickness direction of the mobile phone back cover spot welding non-performing products; and (3) new steel discs are arranged on the spot welding non-performing positions of the mobile phone back cover spot welding non-performing products in the thickness direction of the mobile phone back cover spot welding non-performing products in a spot welding manner to obtain mobile phone back cover spot welding non-defective products, wherein the thickness of the new steel discs ranges from 0.15 mm-0.16 mm. According to the mobile phone back cover steel disc spot welding repairing method, the mobile phoneback cover non-performing products do not need to be abandoned, cost waste caused during mobile phone back cover steel disc spot welding is avoided, and the mobile phone back cover steel disc spot welding yield is improved.

Description

technical field [0001] The invention relates to the technical field of processing methods, in particular to a spot welding repair method for a steel sheet of a mobile phone rear case. Background technique [0002] As a communication tool, mobile phones are playing an increasingly important role in people's daily lives.
