Fillet Brazing Tips and Tricks

[Mr_Rafi]

Howdy,

I'm posting because I'm interested in some tips and tricks from the masters of the fillet braze. I've got my control going well, but I've got some trouble having a constant size to the fillet - not the depth of the fillet at joint, but how far it wets out on to the tubes. Both irregular lines and struggling to make it wet out as far as I want it to.

Plus I just figure there are so tips and tricks out there that would be great to know.

Thanks all.

Try working on more consistent pre heat and rod fill will help. Preheat will help allow the fillet to form consistently, and filler feed rate will allow it to build and flow at the same rate as you move around the joint.

Get the torch tip in there really close and aim the flame on and off the joint to control heat.

I use a Harris #5 or #3. Comparisons can be found here: http://bikesmithdesign.com/Welding/tips.html
