I use 45% silver in the rods i get, and I use oxy/acetelene for most welds, although I am using soft solder more and more

:whistle: how much those 45% sticks set you back?

$11.00 but its good stuff one stick goes a long way

Hey all, i have a problem, every now and then i get a join that wont stick, i soldered 5 joins of 2" bends today, all new, soldered exactally the same way. Cleaned them the same but one join just keeps leaking. Ive pulled it apart 5 times now and spit polished it and its still doing it, fucking driving me insain!!!!!!!!!! :twisted: . Any ideas?. I though tit might be dirt or oil or something, but like i said i cleaned it very very well!!.

Cheers

wouldn't spit leave a bit of residue that might burn?
are you sanding it all back?
using flux? (i think it's not always required copper to copper but can't hurt)

[googe]

Spit polish was just a figure of speach :laughing-rolling: . Yes sanding it, cleaning it, washing it ect ect. I always use flux, i would have thought it wouldnt work very well without flux as th flux creates a path for the solder to flow. Anyway, i fixed it by just reheating and brushing over the top with flux, worked a treat :handgestures-thumbupleft:

Sounds like you might have got the joint a bit too hot ;-)

[googe]

Thans mate, Thats another thing i was thinkng to, do you know if it damages the copper getting it a bit burnt?. Causing it to act like im explaining.

[MacStill]

it dont damage the copper but the burnt flux wont let things stick, you brushed the joint again with flux so it cools the join somewhat allowing it to stick.

a big flame is your enemy using soft solder ;-)

[googe]

Yeah i noticed that about burnt flux, i had to use my big torch cause i was to lazy to go get a refill of the small one, serve me right!. Brushing the join again works great, just makes the solder slide in nice if its messy, also cleans any burnt shit off it.

Doesn't masters and buinnings well it, check in the plumbing section as well as the welding section

[Goldie]

Well should be Sell*

[Gas on]

Its in the welding section at my local bunnings :handgestures-thumbupleft:

[Ryan]

Yeah I checked bunnings (balcatta, Malaga and joondalup), in both the plumbing and welding section, LT venables, and another local hardware store. Running out of options haha

Have you tried Galvins?

[Ryan]

Will try them this morning, already tried this morning osborne park bunnings, toolmart and Osborne park welding supplies to no success. Frustrating as Fuck.

Hey all, need some advice on soldering a gap in copper tube, 2-4mm wide. Have had some success in the past but usually ends in years. Any help would be great thanks :handgestures-thumbupleft: .

Not sure if you will be able to with soft solder but you might be able to brazing
