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,
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.
Quality requirements for resistance welding of metal materials
Part 1.Complete quality requirements
1 Scope
This document specifies the complete quality requirements for resistance welding of metallic materials, including contract and technical review, subcontracting, personnel, equipment, welding
and related activities, welding electrodes and accessories, base metal storage, heat treatment, welding related tests and inspections, non-conformities and corrective actions, equipment
Equipment calibration, identification and quality reporting, etc.
This document applies to the complete quality requirements of welding in metal material workshops and on-site. Appendix A gives the complete quality requirements of resistance welding of metal materials.

4 Contract review and technical review
4.1 General
To ensure that the information required for production operations is complete and feasible before work begins, the manufacturer shall
The manufacturer shall confirm that it has all the capabilities required in the welding contract and that
Ensure that all quality control points are adequately planned.
The manufacturer reviews the contract to confirm.
It has the capability to meet all requirements;-
The relevant documents are clear, accurate and undisputed;-
Have sufficient resources to ensure timely delivery. -
The manufacturer should ensure that any differences between the contract and the previous quotation are clearly identified and the user is made aware of any procedural, cost or other consequences that may arise.
All changes in engineering.
Typical items that should be considered during (or before) the contract review are listed in 4.2.The technical review will generally include the items listed in 4.3.
In the case of design responsibility, the contract review should include the items listed in 4.3.It should be ensured that the user has provided all relevant information.
Where a contract has not yet been concluded, the manufacturer is required to take into account the provisions of 4.2 when conducting the technical review (see 4.3).
4.2 Contract Review
Contractual requirements that should be considered include.
