After, I tried to keep the tacks shallow. I didn't clean it all up since it's just an exhaust pipe but I wiped off an area with acetone and it's nice and shiny metal underneath.Poland308 wrote:Did you butter up the two halves before or after you tacked them up?
Cool! I was wondering if it would interfere with the weld process if it was worked down into a crack. I'm envisioning that you might be able to coat the two sides before you tack up. If there was no way to get at the joint after fit up.
I have more questions than answers

Open your pic in "Paint", save it in correct orientation and reload. Default windows viewers often load sideways, didn't used to but hey MS has to justify an upgrade somehow!

What is that? A hand powered hydraulic coal scorp?
Stone knives and bearskins.....and a NEW EVERLAST 164SI !!!
That's my newly shared work welder.
At home I got a Power Tig 185 DV. Nice, but no plasma cutting... Nice tight arc after a second.

As a point of interest, the elbow on the right is of chinese manufacture. Supposed to be sched40 but actual wall thickness was between sched 40 & 80! And the big thing is that it wasn't 90* !!! What's up with that? You can see the 5G butt is alot wider than the 2G butt, that's because I tacked it on the outside 2.4mm gap (3/32") and had about 8.5mm (11/32") gap to fill on the inside to square it up. Beware crap from China!

I know what you mean about the 90's, we did a lot of 316 pipe work and the elbows were pretty good, got into some duplex and the material seemed really thick for schedule 40, nice looking work there!Coldman wrote:
Saturday job putting in this 5" sched40 crossover. Took me 15 hours including pumpout and re-start. Was a tied joker at the end of the day but still made it out for oysters, steak and beer at about 9pm. The first beer was for my good mate Exie!!

That's a big problem here too. I've had fittings so bad that it's like welding togeather different diameter pipe. Or there not round. That sucks when you have to clock a fitting in a certain position but the one you are up against is out of round in a different direction than the other.

I've been slack and haven't posted much lately.
Getting lots of little jobs now for my motorcycle racing mates. Below is a battery/electrics box for a race bike. Made with 3mm scrap aluminium, filler is 2mm 5356.
Not weldporn by any means, but finding that 1 pps gives me that 'metronome' I need to make my beads reasonably even.
