Post a pic up of your best welds

The colour is right. It's amazing how many newbies get it all grey and crusty looking and I'm not entirely sure why/how.

hahaha, most of my staino exhaust welds are grey and crusty;
Old thoriated tungsten that has welded alloy and everything else sharped on a grinder that has had timber/aluminium/steel ground on it
Welding filler wire grabbed from the shelf covered in shit, maybe wiped with my dirty shirt if I can be fucked
Piping wiped clean with my shirt, dressed with a grinder
Some sort of argon flow between 8-15lpm
Lazy wrong amperage cause I dont like stopping and will just persist


Its all about giving a fuck, I did a turbo intake and if everything was clean clean clean it welded up straw blue like the above but for a dump pipe under a car thats getting rattle canned black, no time for making it look nice.

I was giving someone lessons and they were getting crusty welds. I jumped on machine and it left nice clean yellow and blue welds. I never figured technique alone would have made the difference. I would have figured it would have been more likely to be something on ur list.

So I didn't quite get the penetration of the weld I was hoping for which gives me a few options... This is for one exhaust port exit merging into the log.



1. Leave it.
2. Redo it, more amps, better bevel.
3. Continue as is but re-weld once it's on the exhaust flange with more amps and back purging.
4. Attempt to weld inside.

Anyone?

It will need to be back purged once u anticipate penetration. Strength wise I don't think it will be an issue as it is.

[fantapants]

Yeah I'm with commotion.

Bevel and dual run will improve the peno but you will have to purge and you won't see a significant increase in strength ( mainly for the part you are making)

Imo leave it .... :D

I have been on the welder this week. The heat in the shed has been ridiculous and to make it worse all the harvesting and probably the heat has brought out the marchys.
Some pic of what I been up to:

So managed to get out into the shed today. Well got started yesterday but Anna took of with little Leo for a craft day, leaving me free to get stuck in for a few hours on a project she has wanted done for month.

We have a tiny house. And finding a good sized dining table has proven tough. So I set about making one to the dimensions her ladyship decided were proper.

I have had the steel for this table for like 6months, I just havnt been able to pull it all together.

Proved very rusty on the welder :/ it really is true what they say. Weld every dam day. If you don't you start getting rusty fast. Oh well. All the dodgy was hidden quite nicely with the paint lol.

I decided to paint the table top and the legs separately just so it was easier. Then I'll weld the legs on and only need a little touch up with the paint.

I also have a little plan to fit adjustable feet, but I need to go "borrow" some bits from work.

And the top is going to be some pine from bunnings that is on special at the moment lol.

Just went out to the shed to shut things up and turn it all off.

Dumb cunt here had rested the legs on the touch dry frame paint. Course it was touch dry, not leaning on dry and now they are stuck together...

when using a Tig welder, and say you are a right hander, do you find you hold the torch or filler rod in your right hand?

[Ben Wilson]

Right handed - torch in right hand unless absolutely necessary.

[fantapants]

Generally hold the torch with the dominant hand ... However at my old work th boss was obsessive that all his welders could weld both hands. He had a guy years ago who lost an arm. Took him ages to learn how to weld again. Since then the boss has made it a regular thing in the shop that all the guys can weld passable with both hands. It comes in very handy when doing out of position stuff also. And helps when welding in a mirror when you have to reverse all your movements lol

Tried welding "opposite handed" (torch in left hand for a right hand person) recently while putting a cage in my Datto as I just couldn't get to a few spots welding normally.

I found it almost impossible to co-ordinate torch / filler rod movement.......

[fantapants]

I posted a pic earlier (much earlier) of a vband flange weld on my exhaust for the rocket Ronda. That was done both left and right. I didn't even realise it at the time, just did what worked. Only realised I'd done half of it Cookey when I was looking at the dimes ... Going both directions.

Like anything so long as you practice it works pssabky well lol. And helps get into awkward spots and such .... Not a "needed" skill at all. But comes in pretty handy sometimes

Some photos of the finished machine i posted photos of earlier on the page. I did most of the work on the rear frame section but not a real lot on anything else.
