Jackson Systems announces the addition of SolderWeld soldering kits. Recognized in 2018 as a “Best New Product” at many HVAC and Plumbing industry events, Solderweld is a unique product that produces weld-strength bonds from soldering that work in both soldering and welding applications—two different metal bonding techniques that generally do not mix. Solderweld Kits are conveniently packed to have everything the technician needs for a soldering, brazing and/or welding fix…all in one kit!
10 Steps for 350 degree Multi-metal Soldering
Step 1. Pre-clean the parent metal or
metals to be joined. Use emery cloth, wire brush, bead blasting or your
Step 2. Apply non-corrosive, liquid flux
to the repair area. An easy method of application is to dip the end of the rod
into the flux or use the easy applicator brush. The flux will cling to the rod
or brush and is easily spread over the surface area.
Step 3. Use a soft flame, heat gun or
soldering iron to heat the parent metal adjacent to the actual repair. A direct
flame on the repair area is likely to overheat the solder and flux.
Step 4. Hold the torch tip four to six
inches away from the parent metal. If it is necessary to apply the flame
directly onto the rod and flux, then pull the torch tip back even farther from
the work surface and keep the torch moving.
Step 5. The flux will begin to bubble and
turn light brown. Besides preparing the parent metal for the solder, these
changes indicate the proper working temperature. If the flux turns black, clean
up the area and start over.
Step 6. When the flux turns brown, it’s
time to apply the rod. Drag the rod over the surface area to be soldered until
it begins to flow. Then stop applying the heat. If additional layers are
needed, just continue to drag the rod over that area.
Step 7. Sometimes it is advisable to heat
the tip of the rod with the flame to help the solder flow easier and quicker
onto the repair area. Do not heat the rod to the melting point.
Step 8. Observe the deposit. The solder
should bond smoothly. Do not overheat! The rod will melt if overheated, but the
solder will just lay there and fail to bond properly.
Step 9. If you have stopped the soldering
process too soon and want to flow the deposit out more, add more flux and
re-heat. The flux will help in the bonding process whether adding more rod or
just flowing out the previous deposit.
Step 10. Remove the excess flux with warm
water and a wire brush after the repair has properly cooled.
Torch users using a carburizing flame.This is a flame with less oxygen or compressed air. This softens the flame
and allows the work area to reach proper temperature without the risk of
overheating or damaging the parent metal. Pre-heating the parent metal will
help to insure better bonding.
