Scope

Scope: This document specifies the terms and definitions of welding process technology specifications for resistance welding, as well as the requirements for welding process technology specifications. This document applies to welding methods such as resistance spot welding, butt welding, and projection welding. Main technical content: 4.1 General principles The welding process technology specification (WPS) shall contain the necessary information for performing welding operations, and shall at least include the content listed in 4.2–4.4. When applied in practice, adjustments can be made according to actual circumstances. Appendices A, B, and C provide examples of WPS formats. These formats can be adjusted according to actual application needs. 4.2 Manufacturer-related content The manufacturer-related content is as follows: — Manufacturer's name; — Name and number of the WPS; — Number of the welding process evaluation report (or other required documents). 4.3 Base material-related content 4.3.1 Base material composition The base material composition includes: — Model of the material and related documents; — Type of coating, thickness, and quantity (if necessary). 4.3.2 Base material dimensions The base material dimensions are: — Thickness of the base material at the joint; — Cross-sectional dimensions of the pipe or profile in butt welding. 4.4 General welding process guidelines 4.4.1 Welding methods The welding methods used shall comply with the provisions of GB/T 5185. — Spot welding (21): 1) Manual: Equipment; Welding tools. 2) Multi-point welding: Double-sided spot welding; Single-sided spot welding; Hand-press spot welding; Series spot welding. 3) Mechanized: Single-stage; Conveyor line; Automatic feeding; Robots. — Projection welding (23): Single-point/multi-point; Protruding/solid. — Resistance butt welding (25): Resistance welding/flash welding/capacitor energy welding. — Adhesive spot welding: Manual/me
