It's a good technique for open roots when done correctly, used to do a lot of heavy walled pipe back in the day. You've got to have everything cock on for fillets thoughBob Moffatt did a very informative video on downhill MIG.
Just shows what can be done with good technique and experience.

Pulse is deeper penetrating than normal MAG so Should work spot onUsed Pulsed GMAW vert down for filling and capping years ago on tie-ins on a reel lay barge, wasn't My cup of tea but they passed they bombed ok and are still on the seabed!
Just when you’re on the back of a reel-lay Vessel in the North Sea in December GMAW is a bit less hurricane friendly!Pulse is deeper penetrating than normal MAG so Should work spot on
ESAB TUBROD 14.12 is a bit more resilient to breezes and made for vertical down.Just when you’re on the back of a reel-lay Vessel in the North Sea in December GMAW is a bit less hurricane friendly!
To be honest Brad93 there was not enough deposition for it to be practical in a pipeline environment, We only used it on two jobs because some Welding Engineer thought it was the way forward, looks good on paper but not in practice, Welding 16” heavy walled pipe that is, I could see it being handy for light gauge tanks, silos, farm trailers, skip type application...ESAB TUBROD 14.12 is a bit more resilient to breezes and made for vertical down.

Was mostly GTAW for root/Hotpass, GSFCAW for filling and capping for carbon but GTAW all the way for inconel/inconel clad, duplex etc...Are you using FCAW?
