what rods for thin brass to brass ??

[Mathuranatha]

G'day fellers , the thread about the different colored tipped brazing rods reminded me of something I keep forgetting to find out-
what rods are best for fairly thin {looks like about 1mm or so]brass to brass and what flux?
Using LPG/oxygen

Hi Matt,
I reckon blue tip silver is the go here.

GP silver solder paste .

Brazing rods on brass -1mm thick-_ I can see a big hole being melted in same.

Yep, thats what often happens the brass pretty well melts at the same temp as the brazing rods .So the high silver rods {blue tip] should melt a fair bit lower temp Ok sounds good .
thanks Grahame

Matt
the flux gives the signal to use the s/solder
Paint it on a super clean prepped area.

It will goes pasty liked dried toothpaste.

Heat a smidgin more and flux will start to go clear,water like.

Rub the filler stick against the joint and it should flow when the correct temperature,

Try to use the flame to heat the parent metal not the stick.
Let the heat from the parent metal melt your filler.

Keep the oxy pressure down to a couple of PSI.

Lots of people tend to screw it up way to high and its oxidises the flame and melts the filler with out heating the parent metal.

Cheers
