My company dispatched my apprentice and I to an oil processing plant on the west cost for a crack repair on an oil heater treater. When we arrived in house staff was pulling this E-tube out and washing it for us. During the first inspection inspections a small crack on the exterior side was noticed on the toe of existing weld. After pulling washing and reinspecting a 21” crack was discovered on the back side.
I had E-tube propped up in the best possible position for ease of access on all sides, CARBON ARCED out the crack on backside . (1/2) deep and a total of 25 “ two inches past the the crack and welded her up with 7018 1/8 .
Next day came back gouged out the front all the way down to sound metal and welded it up on the 3rd day.
Front cracks was just as long as the front crack but dug in a lot deeper.
Base metal 515 grade 70 / 1-1/4 thick.
CAC made short work of joint prep. Joint used was referenced from AWS D1.1 (B-U8) CJP

So I finally broke out the check book and got me a new wire feeder that has a large spool capacity, went to the local home depot and pick up a scrap pice of 1"×1/16 tube and started playing with some low settings.
( linked up with linclon's cross linc really well)
Rather than spend 30 bucks for a bunch of tee joints a decided to make bait hook . It's not finished but my point is the profax vs1 was half the price of an ln 25 and came with a connector lug plus 3' of leed. So far happy with it. Can't wait to try dual shield, Flux and spray arc mood,
Welderskills thanks for the mig workbook and all the recent spray arc videos. 😉

Ripped this 1/8 304 plate with a circular saw I have, not sure if it's the same with any circular saw but it makes short work for sure, no sparks no, no smoke.
Thought it was smart to lay out with my chalk line then spray glue, to keep the line. It work till I had to clean it, oh well it's going straight into the fire box tomorrow anyway 🤪.

Just finished the plate rack I was asked to build.
The steel came from left over drops I saved and, an old hammock stand I built a long time ago but never really used.
2x2x 1/8 tube 15' approximately
2" boiler tube .
12 x12 x 1x8 plate
2 hrs a day round up to 8 hrs
Used the CK to pluse tig weld the ends on the boiler tube (mainly to get familiar with the machine and its settings)
The square tubes were welded with a suit case powered by gas driven welder. (GMAW) Dailing in the wfs can be tricky but I got it.
22v 300 wfs/ volts were higher than the recommended 18 to 19 but, I set higher to make up for the voltage drop.
This was a gift but it's always good to know what I could or should charge.
Any feed back or constructive criticism accepted er I 🤔

Still playing with this pluse tig it's pretty cool but, I could see how using it all the time will be a handy cap.

Oil to water heat exchanger.
Got a chance to weld on these 3/4 s.s tube ends to this carbon head plate. It was so dirty oil keep coming out, after stoping oil and Welding I found every time I would weld on a thin spot the weld would pop,
Pretty frustrating, I used the CK machine with a pluse tig feature it helped a lot but, in the end it was the tube expander that did the trick.

Been wanting a cart to store sheets of steel, and also get to with ease. Made it out 2" boiler tube and some 1/8 plate I had laying about. The wheels were also salvaged from the scrape bin, a piece of equipment was beening thrown out so I took the wheels from it.
The tubing was mitercut with the evolution saw "works good but hard to get the round miter cuts lined up for the perfect fit" also hard to get exact length". The sheet was with the slugger circ saw , fresh evolution blade was used since I tortured tested the original with half inch plate bevels. Saw works cool, straight cuts , no dust, no sparks. Chalk line work good to snap lines across the sheet try the blue powder level four.
Welded up the tubing with 6011 3/32 just because a had some. 85 Amp was too hot but did the job , honestly this was a hack job, but I'm happy it's done, it holding a ton of steel I had tucked away and I can easily roll it out now. For what it is it works fine 💪 .

My buddy wrapped his 76 chevy around something on the road and ask if I could cut off the front end. I said cutting off the front end was no problem, aligning it back was a whole another story. Anyways after I had him pull as much parts out of the way, I was able to square off some lines, then useing an oxy-acetylene torch to chop off the front end. Preped all mating edges and tacked in a used front end from another truck. Frist try we found the door panels rubbed, so we Broke tacs off and trimmed mating end back 3/8 at a tapper a got better fit, er I think, its the first time lining up a car frame so I'm pretty happy with it.
💪

Found these old welders for sale, any know what's a good price to pay for one or whether or not it even worth pay for ?

Hello everybody, I work as a boilermaker servicing Various sites daily. My duties vary form Welding (multiple processes) to brazing, to masonry ( Refractory), to threading to fitting to plain old simple mechanical . I also spend a lot of time sharing Welding education with peers and my kids, as well teach a boilermaker apprenticeship program with NCCER.
WTT has always been a go to pointers, but now welderskills is triple up grade if not more with all the different collaborations.
Thanks
