Approximate number of rods per 1 lb. pack for each diameter:

  • 1/8 (3.2mm): 21 - 23
  • 3/16 (4.8mm): 10 - 12
  • 1/4 (6.35mm): 6 - 8

    Tips For Use:

    Clean aluminum down to bare metal using a stainless steel brush, getting off all dirt, paint and coatings.  Cleanliness is essential for a strong permanent joint.

    In some cases a thin layer of insoluble oxide will occur on the surface of the base metal.  This is typically caused by impurities in the base metal and form as you are heating the metal.  The oxide must be removed or penetration will not occur.  When you puncture this layer with the Triple Play rod it breaks up into a fine powder and floats to the surface of the molten puddle.  You can actually see it appear on the surface.  Draw the Triple play rod through the puddle several times to remove oxides and promote fusion with the base metal.  A few strokes are usually enough.

    Localizing of heat techniques can also be utilized to improve the shape of the fillets. If you are joining two pieces of different sizes you will want to apply most of the heat to the larger piece so that they both arrive at the working temperature at about the same time. The repair will harden in a few seconds and can be worked immediately. Do not immerse in water to speed the cooling. The material will be quite hard. It will grind, machine, drill, tap and paint much like a mild steel. Yet when fused with aluminum it is not brittle unless it is cooled too quickly.

    For most jobs, a propane (LP) gas torch is enough.  Make sure to reach working temp of 730⁰F.  Use a general purpose tip.  For heavy pieces you will need a fuel-oxygen torch.  If so, use a large tip with a neutral flame to spread the heat evenly.  Only heat with the middle or outer cones of the flame.

    T-Joints: Heat the parts, not the Triple Play and flow the Triple Play into the intersection. Run the solid end of the Triple Play stick through the molten Triple Play to remove any trapped oxide.

    Butt Joints: If the ends are beveled at 45⁰ angles clean the surfaces and then heat separately. After cooling, brush both pieces again to remove the oxide layer that has formed. Reheat both parts equally and fill in the groove with Triple Play. Cool slowly by fanning the hot weld with your propane torch as you gradually move away.

    Lap Joints: Parts can be tinned and slid together while triple Play is molten, or a generous fillet of Triple Play can be applied around the edges of the lap joint.

    Metered Joints: Make sure material is solidly clamped in place. A neutral flame is applied over the joint area until Triple Play melts along the joint. The joint may be built up and finished as desired.

    Stripped Threads: Drill old threads out oversized so when filled with Triple Play all drilling and taping will be done with the same material making it easier to work with. After drilling, heat base metal from the bottom of the hole beginning at the bottom and working your way up. Fill the hole, let cool, drill and tap as needed.
