Automig 181, it wont penetrate 4mm.

[Wozzaaah]

Which makes it sound like number 1 is gas test then! Try it again and see if the wire sparks when you touch it against some steel (earth clamp on of course).

The reason I say those welds are poor is because on most you've only fused to one edge and on others there's so much spattery build up that there will not be much (if any) penetration.
Look at this picture;

The only parts of that vertical plate that have any fusion is the two inches of weld at the top and maybe one or two spots down the right side. The rest has more or less no fusion whatsoever, you can see that clearly by the rolled over edge.
The other patch in that photo is just held on with masses of spatter, there's no proper weld bead to be seen apart from the 1/2" long one going over the corner on the left side.
The other pic with the angled piece in shows just the same, though there is a bit more fusion in places. The vertical right edge of that isn't joined at all at the bottom, you can see the gap between the plate and the parent metal.

Weldinator, I'm really not being rude, but why are you welding a car when you haven't a clue what you're doing? Who do you want to kill, yourself or evryone else? Those welds are simply not good enough.

Actually, that is rude, but it needs to be said, it really does.

Learn to weld FIRST

What they said^^^^^^^^

You need to learn how to weld first, None of the welds I see in this thread will pass MOT.


You say it doesn't move when you hit it. It is amazing what a ****e weld will put up with, before it falls off, but that doesn't mean it's any good.

 

[Welderpaul]

Granted this weld has been done by a professional plater, on thick plate, and with a machine that costs the same as a small car, but thats the sort of thing you need to aim for

 

[Paul.]

And this is one on something a bit thinner (1.5mm), but using a similar size machine to the one you have hired, as Paul said something to aim for

 

[Weldinator]

Sorry guys for being new to this welding game again, its been more than 6 or more years since i last did a bit of welding, you live and learn then learn some more, in my case anyways lol.

Anyway i had a good night trying more and testing all the settings like i said i would and i think i have made a few good ones. I will post the pics now and may take a while to download from camera and all that.

Tonight i managed to hammer the steel plates in the corners away and there was only about 2- 4 inches in alls worth of fusion, they are strong when not welded properly thats for sure.

Watch this space.

My recent practice and settings testing.

Here are my testing welds i did tonight and i think the left one on section 9 is a good one as is the ones from 25 and 28 sections seem good ones. The section go from 1 top right then goes left as in 2,3,4.,5. The reverse pentration welds are numbered as the first of the line.

wire speed---power number

1) any speed nothing = any power nothing.
2) [ 4 ] --- [ 2 ]
3) [ 4 ] --- [ 3 ]
4) [ 4 ] --- [ 4 ]
5) [ 4 ] --- [ > ]
6) [ 5 ] --- [ 2 ]
7) [ 5 ] --- [ 3 ]
8) [ 5 ] --- [ 4 ]
9) [ 5 ] --- [ > ]
10) [ 6 ] --- [ 2 ]
11) [ 6 ] --- [ 3 ]
12) [ 6 ] --- [ 4 ]
13) [ 6 ] --- [ > ]
14) [ 5 ] --- [ > ]
15) [ 5 ] --- [ 4 ]
16) [ 4 ] --- [ 4 ]
17) [ 4 ] --- [ 4 ]
18) [ 3 ] --- [ > ]
19) [ 4 ] --- [ 4 ]
20) [ 5 ] --- [ > ]
21) [ 5 ] --- [ > ]
22) [ 5 ] --- [ 4 ]
23) [ 4 ] --- [ 4 ]
24) [ 4 ] --- [ 3 ]
25) [ 5 ] --- [ 4 ]
26) [ 6 ] --- [ 3 ]
27) [ 6 ] --- [ 4 ]
28) [ 4 ] --- [ > ]

From the start of welding at number 2 i did the right line slow, the left line faster on almost all of them. I found number 9 and 25/28 burn through going to slow and once i got the speed right i think it ended up being a good weld.
Number 5 set at 4 - > i think was a good weld. The > mark means the last turn of the nob.

Number one did not work on any steel and i did not hear any as going through, just heard the wire feed machine work but rollers not move.

More photos to come, i hope you can see the right sectioned numbers ok, if not i did lable them from the far left section adding up going to the right side. I did give the steel a goood clean even thopugh it looks rust on the pics.

Oh and the gas was set at 10 all the time doing it.

Hope you got all that and let me know your thoughts on my efforts ?

Cheers..

Here are the last ones.

Here are the last ones.

where ?

invisible welds eh it might catch on must be a type of smart repair

edit

ahh thats better they have appeared as if by magic

 

[Weldinator]

My computer over heated after i almost loaded them, then when it came back on i tried to reload the page i was on and it did not work so now i have reloaded them again.

 

[the snooper]

a definate improvement

That is a little rude, we all started somewhere and i wont kill or indanger anyone, im very health and saftey concerned, its only welding anyway.

 

[Weldinator]

a definite improvement

Thanks

I did concentrate more on the weld pool and that is why i blow through a few times. The good ones i said about look high but they are not too bad.

So even though i have improved am i still not quite there yet then ?

Which setting do you think is best to use for 1mm with the reverse penetration picture, i read that too much is no good as is too little ? I think im getting the feel for it on how slow/fast to go depending on the power and weaving technique.

 

[Sanny]

I have a migatronic 181 and the gas test is at zero, no wire will feed but you should hear the shielding gas coming through.

[Weldinator]

I may have missed the gas i am hard of hearing due to ear operations not music.

Oh and i forgot to mention, when i was welding the ok ones i did hear bacon frying or at least it sounded like it.

 

[the snooper]

i did hear bacon frying or at least it sounded like it.

as long as you didnt smell it

i feel hungry now

 

[gavuk]

, its only welding anyway.

......As Snoop says ...much better ,however its much easier to weld on a plate than it is to join (butt weld)2 plates together,knowing that you are pushed for time ,follow the advice given to ChrisB on his "first welds" threads ,if you look at his early attempts they look very like your welds on the car ....do some butt welds using the thin metal technique,then try some fillets,post your pics and get some feed back ,we really aren't snobby p1*s takers here ,but your early attempts were not passable for an mot and thats what you need to aim for ....look at the difference in Chris's early welds and later using "thin metal technique" i honestly believe you will achieve better welds quicker ,iI use the same technique on cars as i use Co2 and you can run hotter ,over 1.5-2mm i don't ,but it will get your welding to mot standard quicker...good luck

 

[brightspark]

as long as you didnt smell it

i feel hungry now

was it danishhhhhhhhhhhhhhhhhhhhhhhhh bacon
good improvement welderator i wonder how many others would have put there 1st welds on here

 

[Iain Westland]

mmmmmmmmmm

You should be flying with this machine, I would have set it up to work on scrap properly before welding anything on the car, good luck sir.
