Induction Soldering

Solder is a molten, metal alloy used to bind two pieces. In induction soldering, metals are heated by an induced electric current. Unlike furnace soldering or brazing, the induction heating process has tight control over the location and extent of the heating. Consequently, heat is delivered exactly where it is needed at the joint to be soldered.

Advantages of Induction Soldering

Neat and clean joints are produced by induction heating, whether soldering or brazing. Because of the exact application of heat, the molten alloy is restricted to the desired working area. Excellent quality control is characteristic of induction soldering and brazing.

The consistency of parts heating tends to lend induction soldering to automation. During a medium to high production run of similar parts, for instance, an automated device could efficiently and rapidly place parts into the induction heating coil. Also, the characteristic control over the entire process makes induction soldering ideal for the electronics and electrical industries.

Soft Solder, Hard Solder

The type of solder used is determined by the metals to be joined. Soft solders are often composed of lead and tin; because of their low melting points, they are used when low temperatures are called for. Hard solders have high melting points; they are used in ferrous (iron) or non-ferrous alloys, such as, copper, silver and aluminum. Some hard solders are also called brazing, although brazing is definitely the proper name when brass is used in the solder.
