Ok ,,gonna be doing some welding ,,its all Mild tube steel roughly 1/8 wall thickness ( maybe lil thicker ) Gonna be gas welding ,,I never gave it much thought before,,as to what rod I was using but I'm told some are better for certain jobs...what would be the best in this application. Thanks
Try 1/16 oxy-rod 65. It's a mild steel TIG rod, but it's of a higher quality than your standard gas welding rod. It should improve your weld puddles w/ less spitting and poping.
I used to frequent a body shop years ago that bought his gas welding wire at the local farm store in rolls. Bailing wire!
Coat hangers have always worked for me as well. Just a walk to the closet. But the real trick is....don't let the wifey see you take'em.
Er702- is for flat welds only. Your best wire is a 6011. It's all position and is forgiving to light rust.
my local ch***is builder and former 40 year US Naval Welding Instructor uses the same thing. He swears by it. I guess he would know. Link below...
??????? I like 6011 but that's an arc welding rod. He asked about gas welding. Is there a 6011 gas rod???????
or do you mean 1109 get it! coat hangers are made from the **** they skimmed off the top of the vat! er70s-2 flat rod???? i have welded miles of that **** standing on my head "over head" the hardest position, on dragsters ,door cars, air planes, ultra lights, lawn mowers, and whatever!! i would use bailing wire before a coat hanger!! unless i wanted to hang up some clothes!
JUST TO BE CLEAR !! haha. i know you are talking about m/s tubing the 70 in er70s-2 means 70,000 psi! it is what i would use on your ".134 tube-rollbar"!! hay wire is good for body work it's soft "dollies out" stretches shrunken welds.
Sorry I miss read. I was told by a guy using coat hangers to weld on a 33 Ford , That it was close to the same metal that the car was made from. Thar for the best to weld it with. But it has no strangth
Wow...I have walked away from this learning nothing, confused and wondering how anyone reads half of what you guys type...can we have some cold hard facts about which gas welding rod works best for .125 wall mild steel tubing? No BS'ing with your buddies, jokes about coat hangers and bailing wire...facts...can we do that? Please?...
ER80s (80k tensile strength) is my main tig rod at work, id probably use 1/16rod with a nice tight joint.... I dont believe gas welding would be an issue. Take this for what its worth haha
Normally, RG is used for gas welding, either RG45 or RG60. For 1/8" material you should probably be using 3/32" rod. I think the ER70S tig rod would be fine also. I have gas welded with all the above.
it is tech week but i didn't it was a tech thread?? sorry we offended you!! but there are threads that other **** heads have posted on here where they have there own ******* contest about who knows the most? woops sorry for rambling and wastin everybodys time b.s.ing about ford rods and chevy oil pans and what the weather is like there!!
ER70-S2 or ER80-S2 are both commonly used for TIG welding but as suggested would probably be a good choice. The 80 is just a little more pure than the 70 which would probably not be critical to you. We use the 80 on our 4130 frames but I have used the 70 in the past. Likewise for Oxyweld 65 if that is what your local supplier has. The thickness of the metal has no effect on what you use, it is all in the metallurgy. The size of the filler rod is also not critical, it just helps to have it close to how wide a bead you want. Using small diameter rod on wide welds simply means that you will use up more length of rod and have to feed it into the puddle faster depending on how wide you want the bead. Just make sure that you get enough heat into the root of the weld so that you are not just laying the fillir rod on top (one of the biggest problems that I see with people who think that just picking up a MIG or TIG torch makes them a weldor (and yes, that is the correct spelling, the welder is the machine) Roo
