Inductoheat - An Inductotherm Group Company

Today Radyne Corporation manufactures controlled atmosphere induction brazing systems that utilize patent pending technology to join these fittings efficiently and cost effectively to fuel lines.  Induction brazing, as opposed to batch heating, provides for better quality and higher energy efficiency as it focuses the energy on the braze joint alone, rather than heating the entire [...]

Frequency selection not only affects the performance of the induction system but it also has a significant effect on coil life. Choice of an improper frequency is the most common mistake made by developers and users of induction heating processes. Frequency selection has the detrimental effect on coil life. An effect of choosing an improper [...]

There are many parameters to be considered in designing an induction billet/bar heating system to meet the needs of modern forge shops. Application experience and computer modeling capability are important tools in developing effective induction heating system and avoiding unpleasant surprises related to common incorrect assumptions. Some of those incorrect assumptions that affect the quality [...]

The stress-relief operation is an important step in the manufacture of a quality connection. Improper heat treatment could result in several undesirable phenomena from total joint failure to a type of bi-metallic corrosion known as “ring-worm corrosion” that occurs in improperly stress relieved or normalized pipes. This corrosion takes the form of a ring around [...]

There are two factors that can cause the overheating: • An increase of power density (heat source) due to the redistribution of eddy current flow. • The lack of adjacent mass of metal there, meaning that there will be reduced heat transfer from the hot surface of the shaft toward the colder core due to [...]

Transistorized induction heating power supplies offer many advantages over equipment which uses older technologies. These power supplies are much smaller and can often be mounted close to the heating coil. Interconnection bus or cable losses can be virtually eliminated. Overall system efficiency is generally higher for transistorized power supplies which means lower electric power and [...]

As a rule, when it is necessary to harden only the tooth tips, a higher frequency and high power density should be applied; to harden the tooth roots, use a lower frequency. A hig power density in combination with the relatively short heat time generally results in a shallow pattern, while a low power density [...]

Friction welding is a remarkable welding process because it is nearly instant and produces very high-integrity, consistent quality welds even with dissimilar metals. It requires one workpiece to be spun at high speed. When scaled up to perform large cross-section welds, it requires a massive machine to furnish the requisite stored mechanical energy.
