I can do oxy welding reasonably well and MIG and TIG (thanks SN) in a pinch. But not arc welding. Nope, stick welding is not for me.

The boy switched off the oxytorch, flipped up his visor, and said, “Mate … I’m not really a welder.”

Why is a weld in steel so much stronger and ductile than the base metal?

And what has been done to make bulk steel and steel coatings with better properties than is possible in welds?

I killed 3 welding irons before I gave up stained glass. Cutting the glass was the easy bit for me.

Impressive.

I’m proud of you.

I’ve never understood why stained glass can’t be put together using resin instead of lead. It’s a lot easier to work with. This thought came to the fore recently because Missy has become an expert in stained glass mosaics.

Also, coloured plastic is cheaper.

But some people like playing with lead.

And mercury, it was used in the hat making process which made the workers a stubbie short of a sixpack.
Luton was a big hat making town, their football club is known as The Hatters.
Not many people know that.

On the bog just then I was just reading about the Luton line and its trainloads of hatters being taken to their hat-making establishments, in an issue of British Railways Illustrated.

So calling them The Mad Hatters is not quite correct then?

The whole of Luton was bonkers, the high street was full of people walking funny and talking jabbawocky.
People would come from miles away just to watch them, and it was cheaper than going to Bedlam.

I trust they purchased a hat as a reminder.

I have never killed a soldering iron and anyway you can’t prove it.

I go into Bunbury.

It kind-of is, kind-of not. I believe that the metallurgy in those areas has the section on the edge of the weld pool – called the Heat Affected Zone (HAZ) – being weaker than the metal on either side of it. I’ve seen a fair few broken parts and the welds rarely fail, it usually fails around the outer edge of the HAZ.

in the course I did, they put our welds in a hydraulic press and the failure had to occur anywhere outside of the weld to pass. HAZ fracture was acceptable, but not prederred

You got a mention in the opening post, SN. Not that it was intended as an opening post. It was originally in the wedding thread. I was being deliberately, straight-faced obtuse there…

Wish i knew how to weld.

Spiny,

very interested in your v8 project, we’ve been thinking of how to do it with a gsxr

Will do, looking forward to the progress

I learnt to weld with the stick about ten years ago – Can confirm that it takes a lot of practice.

It’s almost completely redundant now. MIG and TIG killed it off.

the arson investigator expert today told us a case study about a fire on a luxury 56m yacht that started from a TIG welder who earthed in the wrong spot

Imagine that…. Lightning in the wrong spot caused a fire.

You have to be certain with electricity.

Haven’t done TIG but I’ve done all the others and still prefer the oxy. It is virtually silent by comparison. No slag. I can agree that MIG is good but I’ve got an oxy and all I need to do is fire it up and things get done very well.

Not entirely. TIG is only really any good for very still air and it also very slow. For example I have to do some repair/mod work on a couple of trailers, I’mm be using the MIG for that so it’s done in a few minutes. Using the TIG would take about ten times as long and also can’t deposit enough metal on the weld bead like a MIG can.
MIG’s are a little better with wind, but they still suffer from the shielding gas being blown away. Bloke at where I used to work would often drag out the electric welder to do work outside, when it was a bit windy, as it’s not affected at all.
I’m not sure, but I think underwater welding is also done with plain stick electric welders.

yeah, and Mig or stick it better if the parent material is low quality or unable to get nice and clean.

I managed to get a prize for coming first in my welding class. But very little practical welding in it, only MIG.

I’ve never done any welding since then, but I believe that stick is still the most common, perhaps because it’s the most portable.

I got my name in the Sydney Morning Herald. A in practical and an A in theory.

MIG would probably be the most used in industry and, i would say, getting more common for handyman use. MIG is more portable. I can carry my MIG with one hand but the old stick was a two man job. My MIG will also do stick.

Ta. I’d forgotten about the heat affected zone. Haven’t heard it mentioned since 1978.
