Several years ago…sometime around 1993, I bought my first tig welder.
Around 1996, I got an order for 200 round parts.
The job paid pretty well but I didnt want to spend all my earnings on a turntable without knowing if I would use it often enough to pay for it.
This is some serious gravy work.
I have a lot of rounds parts to weld for a customer.
Any time I get round parts to weld, I prefer to use my turntable.
For this video, I am using an AHP alphatig 200x tig welder.
I bought my turntable off ebay several years ago and it is part of a welding lathe setup.
for this video, I am only using the positioner portion of the lathe but in future segments, i will set up the whole system with a tail stock and torch holder.
Carbide Precipitation is something that occurs when Austenitic 300 series stainless steels are held at an elevated temperature for a period of time. you know…like when you weld a stainless shaft and have to fill the keyway with weld metal.
309 Tig rods are designed for welding stainless steels to carbon steels…but they are a good rod to have in your shop because 309 is a very versatile rod…good for welding pretty much any steel to any other steel in a pinch.
not necessarily the absolute best all around choice…and it shouldn’t be used indiscriminately…but 309 will usually get the job done.
Speed tacking involves setting amperage to 30-50 percent higher than normal welding amperage. Then using a torch switch or foot pedal, use very quick blasts of half a second or less to fusion tack weld.
this makes for very quick tack welding that is clean and free from oxidation.
