Scope

Scope: This document specifies the terms and definitions, instruments and equipment, working environment, personnel, welding materials, assembly requirements, pre-welding preparation, welding process, post-welding inspection and repair for double-wire gas-electric vertical welding (hereinafter referred to as welding). This document is applicable to EH40 grade and lower high-heat input welding steels with a thickness of 40mm to 85mm (delivered in hot-rolled (AR), controlled rolling (CR), thermomechanical controlled rolling (TMCP), or TMCP+T conditions), and vertical butt welds with a plate width position inclination of 80° to 100°, where the welding heat input is no more than 750kJ/cm.
