Lovely looking root penetration ! How many passes ? From your post i make that 5 passes ?


How long does it take to do one weld ?

5 yes. Root pass, two fill passes to bring it up just under flush, then two capping passes.
Can be done in 4 (single pass cap) or even 3, but it distorts a lot, and risks lack of fusion between runs.
As far as how long? Once cut prepped, tacked and purged... id say around 45 mins, as was giving it time to cool due to interpass temps and brushing it well in between each pass.

Good looking weld , I can walk on a flange weld , but haven't had a good go at butt joints , are you using a rotator or welding in a fixed position ?

 

[Liquid Metal]

Was fixed position 6g, as was a code prolongation test. I find it easier doing it on butts than fillets tbh when it comes to capping passes. Easy enough, just dont put too much pressure through the torch or itll just slip off.


Rooting and filling though i prefer to do it freehand. Feels like have better control, especially welding roots.

I need more torch time !

316 Stainless prolongation test this week, done on 3" sched 80.
10l/min purge, 3.2mm root gap no landing. 1.6mm wire 80amps freehand. Size 5 ceramic.
Filled freehand with 2.4wire both passes,
Cap passes were walked with 90amps, size 8 ceramic and 2.4mm wire.

nice but why did you do the upper pass first on the far side ? we would normaly do the bottom run first then the top one or is it just a bit over fill that you going to wash in

the ripples are all going in one direction on the picture of the root ie from 5 o clock clock wise bad pick up at 7 oclock and the tie in i take it thats it at 5 o clock is not too great
some inspectors insist you start at 6 and finish at 12 other wise they deem you to be welding vertical down

I was wondering the same thing zep.
That doesn’t look a fixed position joint to me either as the stop meets the **** end of the start.
Lovely looking joint and the internal penetration is bang on but I’d expect to see the two stop points kissing around TDC from either direction.

The quick description was of the bottom photo, not both. I prefer to freehand a root for a test but i can confidently say it would not be that even lol
The root was part of another job, 4" sch40, but walked and rolled
Sorry, i should have said that in the first place lol....wasnt misleading at all was it
See what you mean now reading it again.

Was a straighter line to follow on the upper pass so i could keep it straighter. When i filled it, came up almost flush on the lower side when was filled, and thought would have struggled to keep it in a straight line. I know it wasnt done strictly correctly but was ok and passed testing anyway, so still jave a job lol

One pic i have got of something i was mucking about with a while ago though was this one. Cant remember if i posted it on here, might have done? Had a go at making a wood burner for the back garden out of some offcuts at work. Never got around to finishing it off though. Might do at some point though.
Forgive the whopping big gaps around the two branches though, marking out and cutting angled branches in pipes isnt my strong suit as can be seen lol

Liquid metal, That tree effect looks spot on, superb!

thats very artistic it could be a rustic 6g welding fixture, just tack test piece on the end of that branch

Realised quite quickly at the time, it wasnt the easiest thing to do to run welds all over the place like that, not after spending 15yrs trying to stay in a straight line lol.

I’ll second that. The bark effect you’ve got going on with the knots looks really brilliant
