    Mathew Associates Hook Up & Weld Services: Welding Procedure Specification

    Uploaded by

    Himanshu Singh
    This welding procedure specification outlines the requirements for pipe to pipe welding using the gas tungsten arc welding (GTAW) process. Key details include welding 1/2 inch and larger groove joints in 1.5-14.94mm thick pipe using an ER70S-2 filler metal with a 2.4mm diameter in the string or weaving technique. Welding parameters such as current, voltage, travel speed and heat input are specified for the root, hot, fill-up and final passes in the multipass joint.
