In my Industrial Engineering lab today we were welding. Most of which the students had never welded. Anyway since I had welding experience I was chosen to weld up all the test specimens to be put into tension test. My weld held up to 10,000 Lbs of tensile force. Unfortunately the weld broke before the metal but I'm by no means an expert at welding. The metal will break at 12,000 Lbs so I got close. Oh well it was fun testing how good of a welder I am.:D I also got to try TIG welding. Man that's hard!:mad: After about 10 min I finally got it to lay a bead. Anybody with TIG welding skills I bow down to you.

hey what welding school is in Haymarket

edit: doh to many:beer: read that wrong nevermind

tig is hard? I always thought it was one of theeasier ways to weld, no spatter, not much waste heat and a nice go peday to controll the arc, I wish i could afford one though

Yeah, TIG welding was easy...Laying down the cash for the TIG machine is the hard part;)

Sounds like fun. PSU, huh, know anybody from Northpenn High School?

chit chat...

Have you tried TIG welding Aluminum? THat's what I was welding not steel. Don't know about steel and TIG.

I successfully welded two pieces of aluminum foil together using TIG....there is a trick though, and I'm not telling :P

TIG is hard to get use to I think...I don't think it would be practical on a 4x, not with all of the whacky posistions we weld under a vehicle.

MIG on steel is a piec of pie, stic is a bit harder

TIG on alumanum is a bitch dont know how well I did cuz I got PO and kicked my pice acros the room and lost it ( I was like fwak this :mad3: )

but TIG on steel ???? U shure about that

Wish the school I went to had a stress tester, all we got was x-rays. Doesnt sound like nearly as much fun. Think the toughest ones to pass were aluminum mig verticle, and aluminum tig overhead. Dont know why those two gave me such a hard time, but it can be frustrating as hell when it takes over an hour to weld up a test plate and then have it not pass because of some spots on an x ray. Did learn that it isnt always the best looking welds that have the best structural makeup tho, but it helps.

I am far from an expert welder, BUT:

Getting your weld to hold 10KSI when the parent material is rated for 12, is like 84% the parent material strength, which is pretty damn good actually, especially if you are "no expert welder"

As for TIG, It is what I learned to weld on, then worked my way down to stick and back up. TIG on any type of steel (mild, stainless, cromo) is like writing with a pencil, TIG on alluminum takes some getting used to, but the only really challenging part is the heat dissipation in the material. It makes things like internal stress of the material a WAY bigger problem.

Now when you start TIG welding titanium... THAT is the shit... Lock it in the bubble and go to town.

Way too bitchin for my shiat though

I find TIG the easiest; but one thing I do have problems with is welding first thing in the morning after a full jolt of Starbuck's high test -- I just can't seem to keep the electrode out of the weld.

JP:rolleyes:

Hell, TIG is what I learned on and all I've ever done. In fact I've NEVER done MIG!

Used to weld stainless vacuum systems and clean process gas lines. Also did steel and Al for various projects at old job. Learned from Uncle. Funny thing was, the first time he was teaching me he said my Al welds were excellent compared to steel (go figure?).

Of course if I ever try to sit down to a MIG I'll probably have the sorriest beads on the planet. :rolleyes:

The puddle for Titanium flows somewhere between CFE and Alum... Not anymore difficult than any other material, just more sensitive to atmoshpere! Welded in a habitat with proper gas coverage and your good to go!
