    Welding Procedure Specification (WPS) : Backing

    Uploaded by

    timkemper
    This welding procedure specification outlines the parameters for gas metal arc welding (GMAW) of a flare bevel groove joint in Domex 550W/301-1/4H steel using ER309Si/ER309LSi filler metal. A single pass will be made from each side of the joint using a 0.045" diameter wire with 140 amps of direct current electrode positive (DCEP) and a travel speed of 30.4 inches per minute at 21 volts. No preheat, postweld heat treatment, or backing is required.
