Any welding tutorials or tips ?
I have never been into welding other than a few heavy duty brackets made with an arc welder, So car body work is going to be a challange, I had a used cheap mig welder which was a bit iratic but i did manage some ok bits of welds on scrap bits, I did some looking around and purchased a Oxford migmaker 200 as shown here http://www.weldingsuppliesdirect.co.uk/ ... phase.html , I would be more than happy if anyone has any links to projects with some detailed pictures of welds and repairs, My welds look a bit like a pigeon has been overhead at times, Also i am not affiliated with the link i used in this posting in anyway just happy with the price and service, Rob

Re: Any welding tutorials or tips ?
I was always taught to write your name in weld on steel with the welding torch, which gradually gives you a greater 'feel' with the torch. Worked for me

Re: Any welding tutorials or tips ?
I will give that a go in the week and try and post a picture of it so we can all have a laugh
Re: Any welding tutorials or tips ?
At least you have a short name to practice on !! Thank God I didn't have to do my Surname ( 10 letters ) when I learnt to weld.

Re: Any welding tutorials or tips ?
I think i should be ok if its flat on the bench, The biggest improvement i have made was changing my old mig welders gas from Co2 to argo shield, So now with the new welder i should even be better, However good ingredients do not always make a nice meal...

Re: Any welding tutorials or tips ?
where in uk are you ? maybe someone local could give some pointers.i spoke to oxford when looking for a welder and the 200-1 is supposed to be a better welder that has capacitors to make a smoother arc,so you have made a good choice there

Re: Any welding tutorials or tips ?
Hi, i Hvae had a guy who works as a fabricator come round to have a look at this welder and i think my main problem was getting it set up correctly, he had it going well in a few seconds, and yes it looks and feels a nice piece of kit, after a bit of asking around a few people suggested portamigs but this oxford is made by the same company and i went for it as it had the capacitor system. I will post a picture of what i did later this week and i was quite happy with it.

Re: Any welding tutorials or tips ?
For rebuilding car body work you should spend some time practising plug welds as well as butt welds. The best advise is to get a feel for your machine before you get to the car. Also try practising welding good steel to cleaned up old steel.
All the best

Re: Any welding tutorials or tips ?
thanks Redmoggy, Thats just what i have done today, I have been clearing up the garage and in between welding to old car panels and i have taken tine to clean and line up the metal, I think butt joins are going to be the tricky part for me but i will keep on trying.
Re: Any welding tutorials or tips ?
Butt welding is always the most dificult to master, try to get hold of little clamps called intergrips which will hold the 2 panels straight, steady and with a slight gap, best to do a series of quick tacks about 1" apart then weld between but start one end weld an 1" then go to the other end and do the same. The main problem will be distortion but there's products like 'cold front' that you put on the panel to absorb the welding heat to stop it spreading and distorting the panel. It's really just high temp soldering and with practice you'll be able to get good strong tidy joints.

Re: Any welding tutorials or tips ?
For butt welding try using a piece of copper (a replacment end for a copper/hide mallet is ideal), hold against the underside of the panel and weld. The weld will not stick to the copper but will be supported preventing you from blowing holes. It will also act as a heat sink helping reduce disstortion. Wear a good hand protection!

Re: Any welding tutorials or tips ?
The only thing i had to hand was some copper tube so i hammered it flat and yes it did work nice and i used it clamped on at the ends so it did'nt blow the edge away, I hope the image post works , this is just random welding on scrap car panel
This is the oxford welder i went for, after looking at a few models i noticed this had a bigger wire feed
and this is how i am welding
but this is a piece i cut off today and cleaned up to test butt welding
as you can see i was a bit off line
but as i was getting down the weld it seemed to go easier
with a grind down it looked better
this is the reverse side
This is my car and in the feature there needs to be some welding so i am trying to get ready for it...
sorry if i have flooded this post with pictures

Re: Any welding tutorials or tips ?
I would say that there is absolutely nothing wrong with your welding, with a bit of practice it will be perfect

Re: Any welding tutorials or tips ?
Not much wrong from what I can see. If your having problems staying on line, try this.
Strike an ark and hold still to form a molten pool, as it begind to glow red draw a small circle with the torch and then stop, before it flashes off move the torch and do the same overlapping the first. You can continue this way for for length of a panel.
This also makes welding thinner metal a lot easier.

Re: Any welding tutorials or tips ?
I had 20 miutes spare so i had a quick retry, the results were a bit mixed,
This is the from the front, Redmoggy, i will try that technique when i am back in the garage later or monday.
The back shows more where i had holes blow through, but i was using no copper ,
all in all i am pretty happy with results so far

Re: Any welding tutorials or tips ?
Well i think all this practice will soon become more prectical as i have found a car to work on for real, its a 1975 MG midget with the 1500 triumph engine in, so if it goes wrong i will have a few parts that might go on a moggy
