Got the frame welded together and then the funnel welded into the frame and all seams sealed up. Next week I'll put the hole in it and then weld up the fittings.

It looks like you passed up a good opportunity for a lot of outside corner fusion welds. I guess that an inside non welded joint could cause product to hang in any weak fit up areas. All in all, it looks pretty nice.

Are you talking about on the pyramid itself? I did weld the outside corners first on that. Since it's stainless and requires no seams, I welded the outside corners on pulse laying in .045 wire as necessary keeping the penetration minimal so I didn't sugar the inside. Then once the funnel was welded into the frame I came to the inside and welded those, also on pulse but just fusion with no wire.

You fusion welded the inside joints? Good job, abit risky but good job. I probably would have done fusion on the outside and filler on the inside but it doesn't have my name on it! You da man, you do it your way! It looks pretty nice.

Thank you. I love using pulse for stuff like that. Gives you all the heat you need but you can sit there for a while before it burns through. I used some scrap to dial in the settings so I was confident I wouldn't burn through.

I was just thinking. I wonder how an added gas shield would work underneath the joint laying the pyramid so the outside joint would all be down hand and then use fusion. Then come back and run a "lay wire" technique on the inside? It would be double expensive on gas but I bet you would have some really attractive welds.

It would work. Definitely would have to burn a lot of gas. Only problem with fusing the outside corners is that the angle they meet at due to being a pyramid isn't 90 degrees. So it really ends up being a groove weld, almost like a bevel you have to fill.
When I weld the tubing in for the 3" connection, I will probably purge through it and tape a box to the inside of the funnel to hold the gas so I can lay a heavy bead on the outside.

Good point on the -90* angle. Holding an appropriate angle overlap would be a bitch. I hadn't thought about that. Carry on! You do nice work. It would be fun to watch over your shoulder, I would probably learn something.

Foot bridge?
Did you weld that in place, or brought it out there?
Don’t see any burn marks in the grass.

Yeah, foot and 4wheeler bridge. No, we welded it in the shop and toted it down there with a trailer. Currently working on the handrail in the shop. That'll be the only thing that gets welded in place.Foot bridge?

It's a crappy picture but I finished up a frame for a hosebed prop at our fire station. Had a company in town make the hosebed itself to mimic our truck so we can keep the trucks put together during trainings. Nothing fancy but a fun little project

Been pretty slow the last few weeks, always is this time of year. We did make a prototype cart for taking parts to/from the wash area (welding every place the expanded metal touched was very tedious) and a stainless chain cover. I also welded up a few tees we are putting in a hydraulic system. They were supposed to get welded in today but we cut into the line this morning and they were still draining 8 hours later so we are coming back tomorrow to finish.

Plan a cargo or flat trailer? Looks like an enjoyable build!
Trying to figure your welder, first thought ESAB, (phone view) though the torch like gas lines out the top have me stumped. Is that an acetylene torch unit and the welder elsewhere or is that the shielding gas tank line?

That’s just a cheap Flameweld 3 In 1 Plasma Cutter Welder Machine.
-50Amp Pilot Arc Plasma Cutter.
-200Amp HF TIG Welder.
-200Amp Stick Welder.
In the picture I just had the plasma cutter hooked up because I had to pop a few holes in the fender to get those eye bolts through to be able to pull that fender across to weld it.. That’s just my retractable air hose you see hooked up.
Tree branch fell on the trailer and mashed the fender so I’m fixing it. Can’t believe it bent the fender that bad as it is super heave duty fenders but it was a big branch.
Trailer has been sitting at my house for about 6 years and the deck boards were junk so I sawed a bunch of 16 foot sweet gum last weekend and I’m just about ready to paint and put boards down and oil the boards with used motor oil.
Then, I’ll put 4 new tires and I'm selling it. I’m sick of looking at it and I don’t use it. It Probobly only has 500 miles on it.
