Introduction

GB/T 45788 "Quality Requirements for Resistance Welding of Metal Materials" specifically stipulates in detail the quality requirements for resistance welding of metal materials.

It covers all aspects of resistance welding, from contract and design review, subcontract services, welding personnel, inspection and testing personnel, welding equipment,, welding and related activities, to welding electrodes and accessories, parent metal storage, heat treatment, inspection and testing, non-conformities and corrective actions, equipment Equipment calibration, identification, quality records, etc. are all comprehensively and systematically regulated.

GB/T 45788 also provides guidance for manufacturers to establish a complete welding quality management system. By following these standards, manufacturers Manufacturers can ensure that the resistance welding components they produce comply with technical regulations and customer requirements, thereby improving the market competitiveness of their products and customer satisfaction.

At the same time, this series of standards can also serve as an important basis for examining suppliers' welding capabilities and quality control levels.

GB/T 45788 is divided into two parts.

Part 1: Complete quality requirements. The purpose is to specify the complete quality requirements and Record.

Part 2: Basic quality requirements. The purpose is to standardize the basic quality requirements and Record.
