commercial pictures ?

Get a pic :smiley2:

More the rods than the current surely? I usually use 2.5 3.25mm rods 6010 and 6013? Minimal spatter just that looked nice.

 

[Scott_D]

Cheap rods will spatter more. I like murex.
2.5 for tacking, routes and small stuff
3.25 for capping and filling / bridging gaps
4.0 for flanges

Have you been welding long?

 

[Ermintrude]

Started when I was 14 , on Gas and mig, playing in workshop / foundry . Only recently started on arc as got some projects to develop. It's horrific !

 

[Scott_D]

I only ever got to test standard on arc. Just takes a lot of practice, patience and a steady hand while you are getting burnt.
Once you have the right amperage for the rod size and angle you are working at it becomes easier.
With a positional pipe weld you have to keep adjusting as you work your way around the circumference.

 

[Ermintrude]

Any tips for welding up bosses onto bigger sections? Bit like fabbing up a headder?

 

[Scott_D]

Are you welding on sockets, flanges, stubs of pipe with a thread?

 

[Ermintrude]

Stubs with thread. Also few 90s

 

[Scott_D]

Lots of prep work. The smaller the gap between the two bits of metal the easier it will be.
You can drill out / blow out a hole for the branch then profile the stub to sit nicely on the pipe
Drill out / blow out a slightly bigger hole so the stub will go inside the header
Get a weld on shoe - its a pre formed fitting you weld onto the header then weld the stub onto it. eg 2" on 6" shoe

You need to apply heat to the opposite side to the branch is welded or the pipe will go like a banana when it cools
You can heat it with oxy-acetlyene or add ribs the the inside or outside
(I will post another pic to explain better)

 

[missplumb]

Yeah get someone else to do it lol!!!

 

[Scott_D]

 

[Ermintrude]

Heat opposite of headder?

 

[Scott_D]

Opposite side of the pipe to the welded branch.
You can see the ribs in the pipe on that pic. Make sense?

 

[Ermintrude]

Ah I see . So run ribs in first?

 

[Scott_D]

Yeah if you do them inside the pipe.
Work through the hole you have cut.

 

[Ermintrude]

How many ribs is there a formula? Rule of thumb?

 

[lame plumber]

watched a welder last year securing some plugs/rods into our keel, stainless steel, as the previous ones had all failed! He was one of the lads welding up our nuclear subs for babcocks I think, as ever its the preparation but once he finished the job you could only just see the weld!! sad to say the boat came back fm refit and the keel had come off and on again, so now we have 10 splatter points waiting to fail.

 

[Scott_D]

Rule of thumb - try and get the same amount of heat into the ribs as the weld.
So if you think a 2" branch will take 6 rods, use 6 rods on the ribs

If he worked for babcock then most of his day would of been sleeping and eating

this is an old install we did a few years ago, 3x steibel ground source pumps, 2x hot water air source pumps.

 

[Ermintrude]

Love all the copper! Nice use of heat mats on ply...... One burn ruins all that work

 

[IDCHAPPY]

Man, me and a multitool with a big scrap bag could have soooo much fun in there :lol:
Lovely install missplumb

thats what happens when you leave apprentices to get on with the job!!!

 

[kris]

Nice n neat , really neat pipework but youl have to issue your apprentice with a heat mat, i always use ply where i can, its extra work but looks neat and makes clipping easy, good job missplumb

 

[Ermintrude]

thats what happens when you leave apprentices to get on with the job!!!

Ok !!!!!! We believe you

 

[mfgs]

Very nice, neat install.

 

[MarkAqua]

some of my sites. I also work at St Paul's Cathedral, Lambeth Palace (Archbishop Canterbury home), London Airports Etc.

 

[MarkAqua]

I will get pics off my old phone of St Pauls. You wouldn't believe the boilers there lol

 

[MarkAqua]

a Manor House near Northaw, Potters Bar

 

[MarkAqua]

just some more. Hamworthy's are at Lambeth Palace.

 

[MarkAqua]

just realised they're on stupid angles. Sorry.

 

[josh]

Good pics mark, i do like geeking out at plant room pics

 

[Ermintrude]

Nice and tidy, gully terminations were a bit of a letdown as was height below headder. Your installs or servicing them?

 

[IDCHAPPY]

I'd give a testicle to do some proper commercial work again

 

[Ermintrude]

I would give both of yours
