View Full Version : A tubing drill I thought I'd share

I'm often asked for ways to practice welding tubing. This is one I do, especially if I've had a long stint of AC and I'm going back to DC or vice versa. It's good for getting my mind back in steel mode or aluminum mode or whatever. I take three 6" (15 cm) long pieces of tubing, cope a 60* on each end, and tack them up in an equilateral triangle. It's challenging to get in the acute angles. You can test your stickout/gas lens/flow rate for best results. I always save the sides for last because I like doing those the most.

And here's what happens when you get sloppy and lose your gas coverage going around a corner on titanium.

Anyhoo, just wanted to share. Hope it helps somebody along the way.

those beads look great..whats wrong with the area of lost gas coverage? the bluing of the metal?

Yes, exactly. Bad torch angle and poof.

other than a color difference, does it affect weld strength or the metal?

Yes, with titanium, the contamination destroys the properties of the base metal.

Zanks practice is just a hair away from being something useful. I really find the shape pleasing. In a way it reminds me of the A-style logo.
