Jaytech Welding & Fabrication

Today we put our new Lincoln Squarewave 200 Tig welder to task welding an aluminum soda can in AC mode! This is not easy, but with the right settings, very do-able. Settings are 30 amps, 75 balance, 150 frequency, #7 nozzle, and 18 CFH Argon. Of course, it’s done with our signature weave weld!

Here you see a couple of aluminum weldments for one of our entertainment customers. The base metal is 6061-T6. The pieces, after machining, are beveled where required, washed, tacked together, then preheated to 200*F. Preheating not only makes welding easier with less chance of cracking, but it also improves the penetration and dries the water moisture from the porous surface of the aluminum.

The welds were done with AC tig, at approximately 200-300 amps, 80% balance DCEN using Argon/Helium inert cover gas mix with high strength 5356 aluminum alloy weld filler.

The other day we had another satisfied customer leaving Jaytech’s parking lot! This is an order of 8 cornerblocks for 12″ truss made for Simpson Stunts! 

We have had a lot of cool projects coming in and out of our doors for the month of March! We have been working on a lot of jobs associated with air travel. We had our hands on a lot of stainless steel, working with plating and processing tanks for use in airbus jetliners as well as galley parts for Boeing 747 dreamliners! We also did welding on a steel engine trunnion for an airship and ordnance ground support parts for the Point Mugu Naval Air Station. Our work on the aluminum bridges for the orchestra walk at the Hollywood Bowl is three quarters of the way through. Another fun project we got to work on was hydraulic cylinder casings for handicap lifts. Last but not least, we assembled skeleton stands for use in museums, sold by a frequent customer company called Bones Clones! These are just some of the bigger projects that we have had in the shop, but of course we always cater to the small walk in repair jobs. Obviously we have been hard at work, but we always hope to be even busier and harder at work next month!

I think my aluminum skills are becoming noteworthy! Here is a weld in the corner of a JBL speaker array frame! – Haley
