My welding projects

admin

Hey,Since I am new here I figured I should post some pics of the projects that I have worked on.  There is a large variety of stuff ranging from pressure vessels to stuff I did for fun.  Enjoy...The first 2 pictures are of a product called a burnout tank, not exactly sure on what it is used for but it is for the dental industry.  Completely tig welded 20gauge stainless.  Fun little project to work on.I figured I would post this because I saw a question concerning fuel tanks the other day.  I welded a fuel tank for my car (the exsisting one had rotted out and was far to expensive to replace).  It is 1/8 Alum, has a send and return line, and a 1" NPT for a fill cap (yes I know the current cap is mild steel...big no no but the picture was taken during my "testing").  The best way to re-weld on a tank that has already had gas in it is to put about 1 bottle of amonia in the tank and leave the fill cap off, let it sit for atleast 12 hours making sure to shake it every now and then.  When you are ready to weld purge with argo. That is the best way I have found. The next 2 pictures are of aluminum pressure vessels for road tankers, these vessels actually went off to Alberta and were used to transport crude oil or something of that nature.  I learnt soo much from my time at this place it was insane.-Paul Attached Images
Reply:continued...The first 2 pictures here are of some practice, I had to fuse some 20ga stainless  but had just broken my left hand/arm in a motorcycle accident (I am left handed) thus creating a small issue for holding the torch.  Anyhow not bad for my wrong hand.The next 3 pictures show 6" pipe schedule 40, tig root pass using 3/32 filler.  The last picture is a bit blurry but was an attempt at showing the root penetration.  I had a weld-test coming up so I thought I should practice. -Paul Attached Images
Reply:contiuned again...These pictures are from the same location as the aluminum pressure tanker, this one was made of carbon steel and measured 56 feet in length, however this one was utilized for dry bulk transport (cement).  I worked closely with the engineers to develop and start a feasable weld process and fixturing process.  Once the peice was out of the jig (first 2 pictures) it went into 2 huge positioners and was welded from the inside frist and then we proceeded to the exterior. This project was alot of fun, by the time the thrid tanker rolled off the line my welder and myself were able to complete the welding in 11 days on 12 hour shifts (no night shift).  -Paul Attached Images
Reply:continued yet again...These last set of pictures are from a job I did recently for a pressure vessel company. The big vessel was TSSA certified, as were the smaller ones.  I am unsure of there use but I know that there are cartridge housings and filters that are placed inside when in use. The smaller vessels visible in the third picture are actually 6" schedule 80 pipe, and I believe all the flanges are 600lbs. Hope you enjoyed, hopefully I will find some time to post pictures of more recent projects and can figure out how to take better pictures.have a good one,Paul Attached Images
Reply:Looks like that shop does alot of work up there. Nice work!John -  fabricator extraordinaire, car nut!-  bleeding Miller blue! http://www.weldfabzone.com
Reply:Keep those interesting pics coming fullytweeked.Some close ups would be nice..What processes are you using mainly? Mig?A good guess is better than a bad measurement
Reply:Hey Brett,Most of pressure vessels there are done using a TIG root followed my a MIG cap, although it varies depending on the drawing and the application.  I much prefer TIG although recently most of the work I've been doing has been stick. Ill practice the close up stuff so you can actually get a look at the beads.Paul
Reply:Are you welding for Beale?  Some of the tankers look a "tad" familiar.
