    The root pass is becoming excessively heavy as you weld pipe in the 1GR position. What corrective action should you take while welding ?

    work closer to the vertical position, progressing downhill

  • 16

    Single Vee preparation on pipe generally have an included angle within the range of:

    60° to 75°

  • 17
