Where did you learn to weld?

[fowler]

Ha true

 

[getting kart smart]

Nice Tv cabinet Fabroman. Is there nothing you can't do?

 

[vpetitgenet]

I do not know and I know that it is "easy" (as some describe it), but is there such a thing as a welding service ? I am sure there is a workshop out there that would be willing to weld, but does anybody know if there is such a thing as welding services ?

Knit. My mum has tried to teach me but I'm just not interested. Also, neurosurgery.

Wanna see more of what I can do? Check this out:

I usually have about 3 or 4 projects going at any given time. Most recently I've rebuilt a box trailer & replaced my workshop bench.

There are (at least, there are around here) guys that bring thier truck to your house/workshop to do welding; a bit pricey though. Most machining/engineering shops will do welding for a reasonable price

I half taught myself......I havent taught the other half yet

I just cant do fillet welds (theyre the 90 degree ones right?) and odd spot welds i suck at

My butt welds are generally very nice though lol

90* welds are easy. tack weld the beginning and end, and then a spot in the middle of the back side, and then lay the pieces so its a v shape and the weld will lay flat. Its not cheating. You should do all your welds in the flat position if you can.

 

[Jfive]

Anything under 200 amps is only good up to 6mm (1/4")

The same principles apply with fillets though; work in small circles or zig zag as you move along.

You don't need 200 amps for 1/4" :wink2: I do 1/4'' as low as 80amps, and get good penetration. 125 is really about as high as you want to go with 1/4".

That with a mig or arc? I cant get good penetration with my 90 amp mig on 3/16 no mater what I do but I can get good penetration with my arc on 1/4 using 6011 rods at 90 amp.

Also, finish reading the thread before you post, you'll find that fabromans post is proved right because me is talking about a mig with gas

 

[CAPTAINCAVEMAN]

sorry to say anything on this subject but arc welding is actually three different types of welding, (stick mig and tig) aka (smaw gmaw and gtaw) aka (shielded metal ARC welding, gas metal ARC welding, and gas tungsten ARC welding)

don't mean to be a nag

 

[exenos]

I was saying arc because it seems to be the accepted short form for smaw, less possible explaining needed. It's also shorter

Picky, picky

I knew you what you meant by arc. I always call stick arc. I was refering to stick, but you should be able to weld 3/16 with flux core wire at 90 amps. I imagine thats what high on a 90 amp harbor freight welder does. Realize that by using flux core wire your able to weld thicker material. Gas might make it easier to reduce splatter, but when you see the ratings of machines there best is with flux. You might want to try gaping the material a little bit, and don't move the torch in circles, or side to side. Also you still don't need 200 amps to weld 1/4" steel even with mig with gas. A 110v mig can do 1/4'' and they don't get anywhere near 200 amps. You should research what your saying before you try to correct someone.

i bought the HF 90 amp (2 years ago?) watched a davesfarm youtube vid on mig welding and taught myself. now i upgraded to a Hobart 140 MIG welder. im taking welding at a tech school this fall..

Here we go again!

Research? I've been welding for over 20 years; is that enough research?
I own a 130amp, 240 volt MIG currently running flux core & I can't weld 1/4". Granted, I've never run gas on this machine so I can't make a comparison but I've used a lot of different machines in the past, the smallest being a 250A.

Also, I noticed you haven't answered the thread question yet...

I admit I don't have 20 years experiance, and I only did the learning classes in welding in school, but I did have a 3.65 gpa and got A's in both classes. One was mig/tig and the other was Arc/mig. Maybe aussie power is differant than american, but I know that I have welded 1/4 steel just fine with a 115v mig welder, and I think people out there should know that they can do the same, and that they don't have to go out and buy a 1000.00 230v mig welder. I am not saying you don't know what your doing or anything, just don't want people to think they can't build stuff with the smaller welders that they have. My comment wasn't for you directly as it was exenos that said I was mis imforming. If you look at the specs for a 210 amp miller they are rated at 3/8". Just cause you can't do something doesn't mean that others can't too. Go to millers site if you don't believe me. I believe its even rated at 3/8'' with aluminum, and as I'm sure you know aluminum takes more heat than mild steel to get penetration. Not looking to argue, but I want to clear up fact from opinion.

Ha after lunch I'm about to learn all over again
At tech

Well, when you do you can tell me I'm wrong...

Being that the information exenos gave came from me as well as his latest experience since I informed him, I take that as you were saying I don't know what I'm talking about.

 

[Br@ndoM@n]

Ur not gonna weld 1/4" @ 80 or 90amps on single pass. Total BS. My hobart handler 140 is rated for 1/4 and even the chart says multipass may be needed. Ive welded thicker than 1/4" with my HH140 but metal is well prepped and multipul pass and welding very slow to insure penetration.

What wire or rod u using to weld 1/4 @ 80/90amps?

 

[Br@ndoM@n]

U think ur welding that thick at those low amps but in reality ur welds wont have enough penetration and WILL fail. Hopefully ur not welding anything structural.

I'm using 6011 rods ( high penetration) at 90 amp. It will do the job, but you have to take your time. Its much better to run 110 or 120 amps. Anymore than that and it starts to under cut the steel.

Note: this is with a Arc not a MIG

 

[Jfive]

when I was refering to 90 amps I was talking about arc, then realized that they where strictly talking about mig, but that still doesn't mean that you have to have a 200 amp welder to weld 1/4" mild steel. Do you agree or disagree. That is the question plain and simple. They said nothing about single or multipass. So that aside am I wrong in saying that you can weld mild steel 1/4 with less than 200 amps. Personally I would care more about if you can weld right than having more than enough heat. what size rod are you using to at 110 amps. I do 6011 3/32 rod at 90. I do 1/8" rod at 115 to 120. I don't like using more than enough heat as the weld can get so hot that it will cause warping. Its good to have high heat when doing small welds where you don't want any cold lap at the start. I am saying I don't agree with you on your statement fabroman, and I don't care how much experiance you have, if your gonna give an opinion and not facts, let people know that.
