Thanks, already on top of that, been practicing positional welding and various angles of jointing tubes with the correct material with the set for a while now. I've had quite a few joints cut, etched and inspected by our metallurgist to ensure sound welds. We're lucky that we've got such facilities at work. I definitely wouldn't take something like that on if I wasn't 100% confident of a quality job.
I've seen plenty of disastrous "attempts" myself and wonder how they ever thought it was acceptable...
