Starting to braze, did I buy the correct rod/flux?

[webdr]

Im trying my hand at brazing and Im going to make a roof rack.

Here's what I bought at home depot;

Mapp gas

bernzomatic plumbing flux

bernzomatic "bronze flux coated" brazing/welding rod. It says "for everyday repairing of steels, cast, coper based, galvanized, or any combo of these metals"

Did I screw up with the plumbing flux? Is there a difference with brazing flux?

The reason I got this is they didnt have a huge selection at the Home Depot and its right down the street.

Im using solid steel rod and some steel brake line.
Thanks

It will work, I think it has a higher melting point than the safety silv 56 that most folks use.

Give it a shot, make sure the metal is super clean and that you dont burn the flux.

how do I not burn the flux? Dont you apply it to the joint before heat, then heat the joint?
or are you referring to the flux on the rod...

If going to the HD is so convenient, take a closer look around there for the Lincoln Electric brazing rods (come in a long clear tube). Not as easy to work with as the Safety Silv, but many times easier than the Bernzomatic rods.

copy that, Ill look for them when I go back.

take some time, find a welding supply shop and get harris safty silv- you will not be able to thank me enough.

the lincoln rods work, but for tubing I found the melting point to be way too high. it works on solid rod, doesnt look too clean but it works.

get the harris.

Your statement is so true. I heated the tube till it glowed bright red and touched the wire to it....nothing...not hot enough. Im going to pick up some safety silver.

I've used the flux coated rods for tubers before. It works great but I use a big act/oxy torch to braze with. I found that the uncoated rods work, and flow flow the best. But what you have there will work.

my local welding shop didnt have Harris silv 56 or the flux so i use UNIWELD. UNI-1000 flux and UNI-1056 silv its the same stuff, brazes awesome.

Good find My local suppliers don't carry the Harris braze or flux, but definitely have the Uniweld. Properties seem to be very similar to the Harris stuff too.
