Welding Tips and Tricks

Woo hoo !! Just found out the paper work went through and I get to take my weld test for my R stamp next week.

Awesome! Good luck with the test Josh!

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.

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.

Another flex from the other day

Sure is!!

Practicing for a brazing cert, copper to copper using Harris Stay-Silv white flux and Safety-Silv 45 brazing alloy

Have to do 3/8" and 2" tubing

I got my welding cart done. I work for a bus company and need the security this setup gives me.

Could a moderator please rotate my pictures?

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!

I only have a smartphone.

Sorry, can't help you there. I only have rotten fruit.

A little weld detail from those Honda manifolds, and my newest toy (RogueFab M600) to play with!

What is that? A hand powered hydraulic coal scorp?

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!!

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!

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.
