Mtaw?????????????

Anyone heard of MTAW, as opposed to GTAW?

I am quoting a part that lists MTAW as an alternative on stainless 316 alloy.

TIA

What does the M stand for?

Are you quoting some parts for a train or bus?......Mass Transit Arc Welding

Only 1 Google hit : Metal Tungsten Arc Welding

But I don't think it is correct.

Metal Tungsten Arc Welding

I think it's a British thing, same thing different words.

Hello shovelon, so I haven't heard of that particular acronym. Do you know what it stands for? If I were to take a guess maybe: "Mechanized Tungsten Arc Welding", but that is just a guess. Kind of like how the europeans use MMA to denote the SMAW process. Best regards, Allan

I saw this in an aircraft welding publication from Australia (page A9):
(apparently a MIG process)

For oxy-acetylene (gas), GTAW (TIG) and MTAW (MIG) welding processes,
examination metal thickness of sheets is 1.6mm thick (this will include material of
0.063 inch thickness).

And a college welding course in Texas:

The program includes entry-level
skills in stick (SMAW), oxy-acetylene (GAS), gas shield arc (GTAW and
MTAW) and flux-cored arc (FCAW) welding. There is a $200 supply
fee per class and a one-time investment of approximately $150 for
personal equipment.

I quoted the job as tig weld so I am good to go.

Thanks.

I still shake my head at that video.

It is like me saying "This is how you drink urine"

One drop at a time. Monkey TIG Arc Welding!!!

I think there's a sticky on of these forums... MIG like TIG arc welding. They also use the term MAG welding overseas for Metal active gas (Co2 shielded)
