Electrode Newbie Questions

[Paul.]

Know pro guys will be used to peelers, but as a hobbyist ya cant beat it

Just something about that beautiful peel up

You boys are easily pleased!, you will usually only get the slag to peel with E6013 electrodes aka rutiles, you'll find other electrodes will have loose slag but rarely peel, all it means is that the current, travel speed and arc length are about right,
This is a 3 pass fillet weld the peeling slag is on the second capping run, that's why it appears to be off centre to the joint, other pic is the completed weld after a rub with a wire brush.

Also tangedfeet as ur a fifer as well i would be interested to see where you find metal for projects, I have a few off cuts from a blacksmith near me that are good for laying beads on but not much use for projects as rather small.

For the vast majority, I buy it. Depending on how much I want I'll either use eBay, or did buy a load from F H Brundle.

For practice I acquired a load of 'tokens' from the lecturer on the college course I mentioned earlier; told him I had a TIG machine at home and would like to practice at home. He taped up a load and passed them to me, telling me not to tell anyone else...

Also, we (I'm a techie teacher, one of the very few that teach Practical Metalwork...) did get given a load of scrap by a local fabrication company several years ago as the scrap prices are so low they tend to bin most; it was all too large or thick for us to do anything with at school as it is too thick for the kids to cut or work with - don't even have the facilities at school for cutting it up. Might be worth asking nicely for some scrap from fabrication companies local to you?

You boys are easily pleased

Damn right we are! Getting your first peeler is a pivotal, definfing moment in the world of the amateur, weekend warrior welder!

Have rung up a few local fab companies, A lot of them order cut to size now it seems so not many offcuts. I am going to try http://www.thomasmuir.net/ down in rosyth its 35p per kg of steel and anything you see you can have so hopefully i get lucky.

Also doing metalwork in CDT , Wish we had that was only ever dead tree carcass for us .

Will have to try a few fillet welds with more than one pass they look quite interesting, may even cut it in half to see how it looks.


Also here are the results i got from the BOC 6013's.

and its less likely to peel if the plate is warm and if its thin....you need the heat differential.

Very true too, one of the "party tricks" we did with first year students at college was to run a rod down a bit of heavy plate and let the slag curl up, but don't go giving all the secrets away, we need to maintain our welding wizard status a little.

We used to save all the tricks for customer demonstrations.....believe it or not peeling slag was never a consideration when testing rods or developing new ones. If the slag came off completely, that was enough....There are some ingredients / alloying additions that completely ruin slag detachability......ever run 347 stainless....they are the worst...its the Niobium / Columbium that does it......no idea why

Well, you two have got rid of the satisfaction of a nice slag peel now.

Its whats left that matters.

Having said that I would expect a good peeler to be a nice weld

Hey Lewis. Few tolks on here have recommended a book called The Science and Practice of Welding, Volume 2, The practice of Welding. The author is A C Davies

I picked up a second hand copy for £2.50 delivered off ebay.

Quite a bit in there I'll never need to know as a hobby welder, but reckon the chapter on stick welding worth the price i paid

Youtube handy too but on there its sorting good from the bad

Couple of videos by Steve Bleile worth a look i reckon.

Thing i dislike about welding vids on Youtube is you rarely see one that isnt American. Which usually means sponsor name dropping by the big welding channels or guys with all the gear and no idea talking complete rubbish

A book..... made of paper , What are you some sort of caveman, Ill have to have a look at that

I know what u mean about the american accent at the start of every video saying " Big Thanks To (Insert Welding Company) And they have a massive setup going with some crazy expensive gear behind them.

Exactly. Dare say my welding would improve if Lincoln Electric sent me a £2000 welder

Lincoln....if your reading this PM me for address, and can i have a Viking 3350 too please ! Same for Lewis, cheers

If you were McLaren or some other racing car firm....you might stand a chance

Well if thats how they want to be Al, I'll try ESAB ....

...I cant say for definite but I think you can probably expect a similar response

I used to get free shirts and once got a nice anorak / fleece jacket
