I was bored today and decided to test out my brazing skills.

I "capped" a 1" piece of copper tube.

Add a fitting, seal it up and pressure test it under water.

Nice job.. Its tricker than it looks isn't it ;)

Next try Steel and Copper. Like a 3/4" steel pipe with a 1/2" copper pipe inside.
You have to tin the steel with 56% then use 15% to fill in the gap. But at the same time do your best to keep the 56% from flowing off the steel. Basicly it sucks.

The base is already polished... you cant polish that black stuff though. Btw how companies braze filter dryers, a/c units, and all those other little brazed things. All those joints look perfect.

Some use the electic heating clamps

But you can always tell which ones they had to do buy hand. Sloppy
