Keeping Your Root Pass Consistent - Tig Welding Carbon Steel Pipe

3-Second Blueprint (English)

1. Consistent 5G Schedule 80 pipe roots start with clean, uniform bevel angles and controlled root-gap fit-up around the joint.
2. Keeping filler wire continuously connected to the weld puddle prevents heavy internal 'nuggets' from repeated rod pullouts.
3. Compensate for gravity by feeding more wire at the 6 o'clock bottom, less up the sides, and letting the top bead sink flush.
