Have tig welded lots of copper thin up to 8mm thick, pressure tested to ASME, lots of preheat required for the thicker stuff. Be very careful of the fume, it can come back and haunt you later in life.
How I went about the long wing and filler tear. After tacking and dressing with planishing hammer for best fit up, long vertical tear run over the area, then another two runs to the left and right hand side of weld one. Same procedure for horizontal tear at filler area, run one at the racks, run...
I was doing repair for a specialist company who deal with vintage vehicles of all type, RR, Bentley etc. The rear wing will be removed for further panel beating to make good. If any of the areas I have repaired crack, which they shouldn't, as I used NG21 filler rod, I will make good FOC...
I was asked if I could sort out cracks and long tear to the rear alloy wing and rear alloy back panel below the boot. Toss of a coin, MIG or TIG? I went with tig, some areas difficult due to being wafer thin, heat sinks required at these areas.
Be a nice motor when restored, not many of this...
Certainly not, feathering back not only offers the welder a nice clean surface to aid restart, feathering also makes for a neater restart and overall better visual view of the completed weld, once the welder is really skilled, you cant see the restarts from the face side.
I was in Edinburgh on Monday, while there I popped along to St Johns Church on the junction of Lothian Rd and Princes St to check out the rather large mural board I fabbed, welded and, Installed ( 3 of us at install ) early nineties, probably before you were born :whistle:
Anyhoooooo, have to...
That's fine, you don't have to see the "point in them". Previous steel gate was top hung and an auto opening gate, extra width opening was required, which meant removing a very large and heavy concrete lintel. Obviously both gates are hinged LHS & RHS of enlarged opening, where weight was and...
Late reply, and to cut a long story short, I replaced rust ridden steel gate with 2 x 3 metre high x 1.5 metre wide alloy gate, I was also widening the opening width to 3 metre. I decided to al/al to keep weight down, and maintenance free, each frame clad with 18swg sheet, 3 x 1.5 metre, sheet...
Awe right Andrew, was that one time not a few times, which was why I bought you an abacus to keep the score :welder::whistle::laughing:
I finished up in January, bucket hung up and no more dancing with the blue lady. My plan is to leave this planet same way as I arrived, naked and skint...
Nice part of our world are the Outer Hebs, I toured from Barra to the top, topped off with a snorkel over the HMY Iolair, what a tragic event that was!
Lincoln set are 13,off in total, I prefer to keep them as a full set and weigh in @ 11.5Kg's
3, off, Modern Weld Practice Vol 1,2 &3 3.5Kg's...
Sorry, I should have said I am Edinburgh based. Fair to say I am trying to avoid the postal route, however, if that is how it has to be, I'll look into it. I'll have to look out the toilet scales and weight what ever book/s it is you are interested in. Then get a cost from my local PO. Which...
I'm having a clear out and rather than binning the books, I thought I would offer them on here, if sold, money will go to Marie Curie.
Looking for a local buyer to collect, as using postal service will be expensive, especially the full suite of Lincoln Electric books.
Cheers..........
Although much of the cost was subsidised, this unique experiment shows what can be done when you utilise all available resources. My old boss was one off, the open uni team.
As Mike stated, resistance welding plant, whether single or three phase, draw down a large current. Ask your mate what power rating he uses to compare.
