How to TIG Braze With Silicon Bronze

TIG brazing using silicon bronze filler rod creates less warping of the metal components you are brazing. This reduction in warping reduces the amount of finish work required to straighten metal body panels and silicone bronze filler rod bonds readily to metal that may contain paint residue or corrosion, lessening the time needed to prepare the metal before brazing. When TIG brazing, your welding machine needs to be properly set and you must use the proper shielding gas to protect the puddle of melted silicon bronze filler rod during the brazing process.

Instructions

1

Connect a bottle of argon shielding gas to a TIG welder and set the pressure of the flow meter to the pressure specified by the silicon bronze filler rod packaging.

2

Put on leather work gloves and safety glasses.

3

Attach a 4.5-inch wire wheel to a 4.5-inch angle grinder and clean the pieces of metal to remove the majority of the paint and rust from the metal. The metal does not have to shine, but the majority of the rust and paint need to be removed from the area to be brazed.

4

Put on a welding hood and turn on the TIG welder. Set the TIG welder to the voltage specified on the silicon bronze packaging.

5

Lower your welding hood and start your TIG welder.

6

Feed the silicon bronze filler rod into the TIG arc, covering the seam in the metal pieces. Pull the TIG torch along the joint while you continually feed the silicon bronze filler rod into the welding arc.

7

Allow the brazed medal joint to cool thoroughly to ensure that you do not receive any burns from the hot metal joint.
