learning to weld

[dave123]

hi all I am trying to teaching myself to weld and need advice on my welds do they look ok and how do you weld a 90 degree angle I tried on the same setting and it just blew threw and made a mess . the pic is using a Clarke 130en set on 1/min and wire speed 6 the 2nd pic that marked 1 is 3 pieces on plate butt welded

practice practice practice and a fire extinguisher :lol

here is the 2nd pic

looks pretty good with decent penetration :naughty

best thing to do is play with the settings, you will soon learn whats best for what you're welding :thumbs

Butt weld two pieces together, then place it in a vice and knock from side to side, if the metal bends, great, if the weld cracks...
As said before...
Practice, practice, practice...

I bought a cheap Mig, cheap as in half price, from Halfords many years ago, It is great for non stressed items, that don't matter if they crack again, like an exhaust bracket, or a quick fix on the exhaust, BUT I would not weld structural items like sills or chassis or seat belt mounts, I don't get enough practice.:doh

I welded up the old lawn mower, the rot went 1/4 around the top, with a few steel brackets welded on, it seems strong enough. But I have since replaced it with a new one.
I also welded up the neck of a garden fork, seems ok, but might crack soon.


Years ago, I once tried to stick weld a mini sub frame....:doh
BUT by the time I found good metal, there was nothing left.:nenau
A new sub frame at the time was £25 but that was over thirty years ago.
But then, that cost was only part of it, by the time you replaced the brake pipes and all the bolts ....:augie

Have a look on the mig welding forum (if you haven't already):thumb2

No skill required in mig welding tbh. Only one thing to remember is that you need to push not drag ie torch should be angled about 85 degrees with wire pointing in direction of travel

got to disagree with that. i have seen many welds that are not up to the job.. true mig is much easier than tig and stick.

because somebody manages to stick 2 plates together does not make them a welder. on panels its not bad as its not structual ( sills) but once your on a chassis the weld should be a good one with correct penetration.

too much penetration causes a weak joint and the heat effected zone is what will split not the weld run itself. that well be the bit changed colour and the weekest part of the this will be down the edge of the weld.

not enough penetration ant the weld will crack/split


the weld picture at the top has too much juice or the man with the welder is movins slow and needs to speed up. very intrested in seing the reverse of that

Ive been welder for 28 years apprentice trained i also teach people to weld aluminium to vacuum standards.You could learn to mig weld to automotive standards in couple of days very little skill or hand control required try tig welding 30mm ali different story

 

[larson]

then i have to bow to your superiority

im not apprentice trained but do it for a job. do you teach to apprentace lvl?


still think all i said above is correct , although i cant argue against your paper work i have seen some weld on here and other forums i would not want on a car of mine

Have 1 full time apprentice also teach others to ali weld its difficult to employ people with those kind of skills in this area with airbus and rolls royce just up the road

I have been trying to do some fillet welds to make a tee joint and its not going well . I am doing it with 2mm plate . the setting are fine when I do a butt joint on the plate doesn't blow threw and have good penetration. but as soon as I try the tee it becomes blobs and then blows threw plus I even had the wire burn back and melt the nozzle . can anyone explain to me how and where I point the torch to on the metal . (ei deep in the corner or to the top metal or bottom and do you point it in from the top or more from the side and do you pull the weld or push it away ) .

Point it right in the corner always push with mig

How much do you charge to teach welding?

I have been trying to learn for sometime, and have been looking around for courses etc (Gloucester/Bristol area).

Can't really do that at my work . what sort of welding are you looking at learning. Think Bridgwater college have short courses that's where our apprentice goes not sure if there any good
