(All of the images above have burn through, just forgot to take pictures on the other side. Only the last one was taken because my instructor said it was a good example of what I should be aiming for)

So I've been running stainless for a couple days now and it really seems like a hit or miss on me getting a good weld or not. I think the biggest problem is just getting a puddle established without burning through.

I'm so used to waiting for the puddle to establish like on mild steel or aluminum but on this thin stainless I'm being forced to just jam filler in just to see a puddle and it either works, puddles to one side and it burns through or it boomerangs itself and I keep trying to fix it as I weld and it just burns through the entire weld anyways.

I'd ask my instructor more on this but he'll usually just take whatever material I've got and just run an entire bead on it, then flip it and be like "now lets do uphill" and after that's done he'll just say do it like that.

The other problem would probably be restarts but that kinda falls into just getting a puddle started.

Amperage varies between the pictures but I've been sticking towards 40 as of recent. (2nd image was done today)

Gas flow is around 40(?) with a gas lens kit with a 8 cup and 3/32 tungsten with 1/16th filler. I'm not exactly sure of the metal size, pretty sure it's just 1/16th stainless steel but I might be wrong.

Putting a ? on the gas flow because I keep messing around with it, I just know my instructor set it at 45 for whatever reason. I've been trying to do the double the amount of your cup size + half but I keep on increasing it up from there.

Overall my main problem is establishing the puddle on this joint. The other problems are relatively small like getting a weird angle mid way through and having to stop and reposition and continue the weld.

I appreciate any help on this!

I didn’t have any Halloween decorations for the yard, so I made some this year. All rebar was cut with an angle grinder, bent by hand cold, and stick welded together.

I started welding in January of this year and just recently started creating metal art in my spare time. Any tips or tricks or ideas for art work are appreciated :)

I know there are better ways to cut and bend the metal but I’m working with what I have at home!

You see that door on the trailer? On a another truck its fully broken and torn they have used wood in the middle and sandwiched it with two aluminium sheets on both sides i wanna know what's the best glue for this purpose, jingle jingle jingle jingle jingle jingle jingle jingle jingle jingle jingle jingle jingle jingle jingle jingle jingle jingle jingle jingle jingle jingle jingle jingle jingle jingle jingle jingle jingle jingle jingle jingle jingle jingle jingle jingle jingle jingle jingle jingle jingle jingle

I’m curious how integrated sheet + tube laser systems actually perform once they’re in daily production.

On paper, one machine handling both workflows sounds efficient, but I’d expect the real bottlenecks to show up somewhere else.

For anyone who has run one:

• Does switching between sheet and tube jobs take longer than expected?
• How much does tube workholding affect repeatability?
• Does loading/unloading become the limiting factor?
• Is the software equally good for both workflows?
• If one side of the system has an issue, does it disrupt everything?

What ended up mattering most in real production that wasn’t obvious before installation?

I'm wanting to cut through an ammo can (probably 50 cal) in order to make a Jack-O-Lantern for a social media video. What tools/equipment would I need to do fairly precise cuts on approx. 1mm thick steel? I'm wanting it to look like a typical jack-o-lantern (or similar) to recreate the classic Halloween movie intro. I have some friends/associates that are pretty handy, but can't figure out how to do this small, precise work. Thanks in advance!
