Brazing is a joining process whereby a non-ferrous filler metal and an alloy are heated to melting temperature (above 450°C; 800°F) and distributed between two or more close-fitting parts by capillary action. At its liquid temperature, the molten filler metal interacts with a thin layer of the base metal, cooling to form an exceptionally strong, sealed joint due to grain structure interaction. The brazed joint becomes a sandwich of different layers, each metallurgically linked to each other. Common brazements are about 1/3 as strong as the materials they join, because the metals partially dissolve each other at the interface, and usually the grain structure and joint alloy is uncontrolled. To create high-strength brazes, sometimes a brazement can be annealed, or cooled at a controlled rate, so that the joint’s grain structure and alloying is controlled.

Soldering is a method of joining metal parts using an alloy of low melting point (solder) below 450 °C (800 °F). Heat is applied to the metal parts, and the alloy metal is pressed against the joint, melts, and is drawn into the joint by capillary action and around the materials to be joined by ‘wetting action’. After the metal cools, the resulting joints are not as strong as the base metal, but have adequate strength, electrical conductivity, and water-tightness for many uses. Soldering is an ancient technique that has been used practically as long as humans have been making articles out of metal.

Soldering can be done in a number of ways, including passing parts over a bulk container of melted solder, using an infrared lamp, or by using a point source such as an electric soldering iron, a brazing torch, or a hot-air soldering tool. Flux is usually used to assist in the joining process. Flux can be manufactured as part of the solder in single or multi-core solder, in which case it is contained inside a hollow tube or multiple tubes that are contained inside the strand of solder. Flux can also be applied separately from the solder, often in the form of a paste. In some fluxless soldering, a forming gas that is a reducing atmosphere rich in hydrogen can also serve much the same purpose as traditional flux, and provide the benefits of traditional flux in re-flow ovens through which electronic parts placed on a circuit card are transported for a specific period of time.

Ameritherm

Precision induction heating solutions are our specialty. We won’t send you an oversized power supply and hope it works by brute force. No two heating applications are exactly alike, and neither are our customers!

Our approach is first to listen to your unique needs and concerns. Then, we’ll invite you to send samples of your parts to our Applications Lab for a NO CHARGE evaluation and system recommendation. Benefit from the advice of experienced applications engineers who have worked with parts of virtually any size and shape. Let us show you the Ameritherm difference!

Pillar Induction

In 1966, Pillar forever changed the induction industry by introducing the first solid state power supply. The inventor of that first induction heating power supply, Phil Landis, continues to be a part of our success by actively mentoring our new generation of design engineers.

A decade later, we introduced the first transistorized induction power supply, as the technology of the future. As you would expect, we are continually working on new designs to improve our products and get the most from the available technology. The result of our efforts is the broadest line of reliable products available in the industry today.

In 1986, Pillar acquired Westinghouse Induction Systems, and in 1989, we acquired Cycle-Dyne from Lindberg, a unit of General Signal. These strategic acquisitions added breadth to our already extensive product line. We are uniquely positioned in the market, with products in every size and frequency rating.

In 1995, Pillar opened the Michigan Induction Center to service our Heat Treating customers. This facility is home to seasoned professionals in all aspects of induction heat treating. Whether it be production processing or prototype work, Pillar has the equipment and staff to meet your needs
