Pipe Welding with Lincoln STT
Pipe Welding with Lincoln STT
(OP)
I am considering Lincoln STT for up to 3/4" thick st. st. pipe, up to 30" diameter. Work will be done in a shop, so pipe rotation will be done. Experiences and advice on joint design and techniques (especially position) sought. Also purging techniques/materials.
I understand Miller has a similar technology but I have not yet investigated.
Thanks

I am curious about the performance of Tip-Tig. They claim even more production speeds.

I've since learned that STT is only good for the root pass, but a Lincoln Power Wave with STT option can complete the job in normal GMAW. Sounds like a good way to go.

I said Tip-Tig, a machine that an acquaintance of a friend developed. It uses the GTAW process but feeds the wire by a controller on the torch. There should be no limitation on thickness. I haven't even heard of Top-Tig until your post so thanks for the info.

I don't have those issues and can't locate the articles on the www. Any chance you or anyone else can post them here?

Better yet, just the details of wire Ø, gas, purge parameters and joint design for a root pass with ER309L.
Thanks muchly.
