A beginner s guide to welding brazing aluminum with alumiweld rods.
Brazing aluminum gutter.
Apply the flame to the joint until it s hot enough to melt the rod.
Aluminum brazing fluxes consist of various combinations of fluorides and chlorides and are supplied as a dry powder.
For torch and furnace brazing the flux is mixed with water to make paste.
When you sweep the tip of the rod through the joint it should melt in.
When everything is cooled off you ll have a strong joint.
If not heat the joint more and check it again with another sweep.
You will need to track down a specialized solder or brazing alloy intended for use on aluminum or for joining aluminum to a different metal depending on your project.
When compared to welding equipment aluminum brazing equipment is inexpensive portable and does not require high amounts of voltage.
You want the metal to melt the rod not the flame.
Aluminum is a real challenge to join without specialized welding equipment.
