Anything welding

you should be able to weld the muffler with the 90.

 

Nice, might try to give it a go tomorrow. If it doesn't work I'll just take it to a shop like I would have. I'll post pics pics if I get it done. Thanks Jerry and nice welds.

 

The welder should be able to do it, but can you?

 

Either

 

I've been using my dads millermatic 140 for a little bit. I can get two pieces of metal to stick together but it's sure as hell not pretty. I welded my shooting target back onto its frame and I'm ghetto fabbing up this box to will attach to my bed rails and hold my fuel can right now. I'll post a picture when I finish it tomorrow. I'm using cheap China metal that we had in the backyard that was used as packaging support for some awning or some shit. I keep having problems with the welds burning right through the metal unless I do quick little tack welds mainly. I'm trying to piece together some scraps so I can keep practicing Anyone have some diagrams on basic welding patterns I could test out?








Here's a professionally done rendering of my design. I'm going to reinforce the side with the brackets on it so that I can drill holes to run two bolts through it and attach it to this thing my dad was showing me that fit into my bed rail slot. Then I'll just have to run a little bungee over the top of the can so that it doesn't fly out.

I tried to do this weaving design but I just ended up burning holes into this metal so I stuck with quick little tacks across each gap. I already know I didn't grind it down well enough so that's a factor. What kind of weld would you use for my "pillars" that I'll have to weld to the base frame. Will my little tack weld like in the second picture work? Not looking to make a super indestructible box, just something that can hold 35lbs in place.

Did a quick read and it looks like I should take my wire speed off auto and maybe play with the manual settings or something. How far away should my tip be from the metal? Do I want a 45 degree angle? I just measured the thickness of the metal. It's 1/16" thick haha.

 

Try keeping the tip 1/2 to 3/4" away from your joint, also it sounds like your welder in turned up a bit too hot. Try turning it almost all the way down. 1/16th is really thin and it doesn't take much to burn through. You might be stuck with welding a spot, waiting a sec for it to cool down, than welding anther depot... etc repeatedly.

 

Ya or maybe turning the amps down? I'm in a welding class right now and I sucked at MIG, there is a picture a page back or so of what I did. TIG aluminum I found to be much easier.

Just looked it up. 1/16 thickness sheet is supposed to be between 80-120 amps.

 

The 140 has a chart inside the door. You can use that to set the wire speed and heat ranges as required. If you have a smart phone, Miller even has an app to help with that.

But if you're burning through, definitely too hot.

 

Oh yeah. http://www.weldingtipsandtricks.com/ to learn more about welding.

 

Heres my TIG aluminum welds. Way better than anything I've done with steel unfortunately.

 

lol Im the opposite. My aluminum doesn't look half as good as my steel welds. Those look pretty good.

 

Thanks, Ya I kinda wish I was better with steel, its a little more useful haha, but hopefully I'll get there with some more practice.

 

Thanks for the help guys. I checked out the app just now and it said the smallest wire size was at .030" and I'm pretty sure my wires .024" but I'll double check after work. I bookmarked that site as well.

 

Stainless Steel all day everyday.

 

Is welding stainless steel any trickier than regular steel?

Here's an update on my ghetto fuel can holder:



Went to home depot today and picked up some 3/8" thick metal stake. I'm using it to run the bolts though as the other metal wasn't thick enough.



Practiced trying to get a cleaner, longer bead. I turned down the power a bit from about 6 that I had it on to 4. It worked better but it's still ugly as hell




Still need to cut four more pieces and make some pillars out of them. Then I'll just drill the holes for the bolts, grind down and neaten up the edges and throw some paint on it.

 

Yeah if you can't weld mild steel, stainless is going to be a big pain in the ass, especially with mig. To start, you will need different wire and gas

 

Heat looks okay but you need to slow down, you are moving too fast. You also need to concentrate more of the heat to that thicker piece on top

 

Is there a difference in practice on using a single, flat piece of metal to try and lay beads on versus using two pieces that I would practice welding together (like in the above picture)? I could just go back to home depot and buy a couple stakes and practice on those or something.

 

Get a couple pieces. Get a piece of plate that you can just practice laying beads on, and get some flat stock that you can practice doing butt welds, lap joints, tee joints, and corner joints with

 

Don't go buy steel to practice I have tons of scrap you can have to practice with. I'll bring you some to the meet or if it's here at the shop you can just grab some.
