Muggy Weld SSQ-6 is simple to use on brass–just squeeze out the amount needed on the brass before you heat the part with your choice of torch. Apply SSQ-6 to cold brass, then heat the parent metal to flow the solder.
Brass is an inexpensive alloy comprised of copper and zinc that has many useful qualities. Corrosion resistant, aesthetically pleasing, and strong, brass is widely used for a variety of industries. Its corrosion resistance makes it an ideal choice for marine applications such as pumps, marine engines, and pipes. Many automotive repair shops opt for brass radiators vs. aluminum due to its ease of repair, and heat exchangers, heater cores, and air coolers are typically brass. Musical instruments, fixtures, fittings, jewelry, and appliances… the list goes on and on.
Mike uses a propane torch and SSQ-6 silver solder to bond a brass washer to a brass nut. It is necessary to pre-clean the brass, and for these small parts we used a piece of wire to create a gap between the welding surface and the joint in need of soldering.
With or without the precision tip, apply the solder by gently squeezing the plunger. Do not press to hard, or you may break the syringe.
Broadly heat both brass parts with the propane torch. The brass will turn a dull red color when the metal has reached SSQ-6’s 1150°F. SSQ-6’s flux is incorporated into the solder paste, so when the brass reaches working temperature, the solder will flow and follow the heat. Continue to broadly heat, front to back, side to side until the entire joint is bonded.
Air cool, then remove residual flux as directed.
Caution: Do not store near edible items. If you refrigerate SSQ-6, please store in a “chemical only” designated refrigerator.
