|Soldering Methods for 6061-T6 Aluminum|
|Keywords: 6061-T6, Aluminum, Soldering|
|A very popular aluminum alloy is 6XXX series aluminum, designated 6061. A common form of this alloy for many types of construction is 6061-T6. By developing different methods to solder this aluminum alloy, many low-cost options are opened up for joining 6061 to itself or to other metals, such as copper, brass or steel. The methods developed for soldering 6061-T6 aluminum include solder-coating, using flux-cored solder wire and new, stronger, direct aluminum solder paste capable of soldering 6061-T6 aluminum. Evaluation of these soldering solutions was done primarily via tensile testing of the soldered joints created by these methods. Further studies involved humidity testing, salt environment testing, solderability testing and scanning electron microscope evaluation of the soldered connections.|
