Process A multi-turn helical coil is used. The part is heated to determine the time required to reach the desired temperature and required heat pattern. It takes approximately 30 - 45 seconds to reach 1400°F (760°C) depending on the various part sizes. Flux is applied to the entire part. A braze shim is sandwiched between the steel shank and carbide. Induction heating power is applied until the braze flows. With proper fixturing, concentricity of the part can be achieved. Results/Benefits • Repeatable, consistent precise heat.  

Induction Hot forming and Forging Process

Induction Hot forming is a process in the manufacture of industrial fasteners such as bolts, screws and rivets. Heat is used to soften the metal which is usually a sheet, bar, tube or wire and then pressure is used to alter the shape of the metal by performing any of the following operations: hot heading, blanking, punching, slotting, perforating, trimming, shearing or bending. Besides, billet heating is also a process best performed with induction hot forming. SAMSUNG DIGITAL CAMERAModern induction heating provides many advantages over other heating methods and is commonly used for bonding applications. Heating through induction provides reliable, repeatable, non-contact and energy-efficient heat in a minimal amount of time. Induction heating is also ideal for in-line production processes because of its ability to produce repeatable, rapid and accurate heating cycles. Hot Forming and Forging, hot stamping and extrusion consist of forming a part that has been previously heated to a temperature at which its resistance to deformation is weak. The approximate hot forming temperatures of the most commonly used industrial materials are:

• Steel from 1100 to 1250 ºC
• Brass 750 ºC
• Aluminium 550ºC

After heating up the material, the hot forming operation is done on different types of machines: mechanical impact presses, bending machines, hydraulic extrusion presses, etc. The starting material used in forging is presented in the form of rounded studs, squares (billet) or bar materials. Conventional furnaces (gas, fuel) are used to heat the parts but also induction can be used.

Induction heating advantages:

• Material and energy saving plus flexibility
• Greater quality
• Process control
• Much shorter heating times
• Less oxidise and the production of scale is very low
• Easy and accurate adjustment of the temperature to be applied
• No time needed for the furnace pre and maintenance heating (for example after or during the weekend when it takes more time)
• Automation and reduction of the labour required
• Heat can be directed to one specific point, which is highly important for parts with only one forming area
• Greater thermal efficiency
• Better working conditions as the only heat present in the air is that of the parts themselves

The process of forging and hot forming is a common process in the manufacture of many industrial sectors such as automotive, railway, aerospace, oil and gas, chains and forging.

principle of electromagnetic induction heating

principle of electromagnetic induction heating

In 1831 Michael Faraday discovered Electromagnetic induction heating. The basic principle of induction heating is an applied form of Faraday’s discovery. The fact is that, AC current flowing through a circuit affects the magnetic movement of a secondary circuit located near it. The fluctuation of current inside the primary circuit provided the answer as to how themysterious current is generated in the neighboring secondary circuit. Faraday’sdiscovery led to the development of electric motors, generators, transformers, and wireless communications devices.Its application, however, has not been flawless. Heat loss, which occurs during the induction heating process, was amajor headache undermining the overall functionality of a system. Researchers sought to minimize heat loss by laminating the magnetic frames placed insidethe motor ortransformer. Heat loss, occurring in the process ofelectromagnetic induction, could be turned into productive heat energy in an electricheating system by applying this law.Many industries have benefited from this new breakthrough by implementing induction heating.

handheld induction brazing HVAC tubing

Handheld Induction Brazing HVAC Tubing

Refrigeration piping is always brazed as brazing makes a very solid leak-free joint that withstands high and low temperatures and pressures. When soldering refrigeration pipe it is best to use solder which has a composition of silver in it as the silver bounds with the copper and makes for an excellent leak free strong joint (capillary attraction). HLQ Induction are experts at devising customized induction heating solutions for brazing of compressor parts, heating elements and heat distributors. Air conditioners have several parts that are brazed. The most common materials are copper and aluminium: Aluminium parts, for example evaporator and condenser connections (tube-to-tube, tube-to-block, tube-to-tank) Tube-to-fittings on the condenser unit Tube-to-fittings on the evaporator unit Tube-to-fittings on the compressor Tube-to-valves in distribution systems Induction Brazing is similar to soldering except the temperature is above 800 degreesF. For copper, the brazing compound most commonly used is commonly called sil-phos as seen on the left. There are several types of this compound. 15% Phosphorus/Copper/Silver Alloy is one type that uses 15% silver and is the standard for service techs doing repairs of refrigeration equipment.5% Phosphorus/Copper/Silver Alloy is another compound that is cheaper and some say works well for repairs. It does not work as well as 15%. There is also a Phosphorus/Copper Alloy with no silver that I find to be largely useless for repairs. Copper Brazing for the HVAC Industry Multiple copper tubes silver brazed by MSI Automation's proprietary induction brazing technology.Induction heating with the proper induction heating coil technology can silver braze multiples of copper tube ends in one shot. This procedure eliminates tedious hand torch brazing, improves consistency and reduces the chance of leaking connections. Joint brazed between the copper tube and brass body is complete. Heating time using MSI's special induction heating coil is 1/4 that of conventional round copper tube coil designs.

Material Stainless steel braided hose 3/8” (9.5mm) OD, copper elbow 1/4” (6.3mm) OD, braze preform rings and black flux Temperature 1400 ºF (760 ºC) Frequency 300 kHz Equipment • DW-UHF-6kW-III induction heating system, equipped with a remote workhead containing two 0.33μF capacitors for a total of 0.66μF • An induction heating coil designed and developed specifically for this application. Process: A two turn helical coil is used to heat the braided hose assembly. Braze rings are placed at the joint on the copper elbow and flux is applied to the entire surface of the assembly. The assembly is placed in the heating coil and the braze flows within 30-45 seconds. This creates a liquid and gas tight braze between the copper and stainless steel braided hose. Results/Benefits Induction heating provides: • Liquid and gas-tight braze • Energy efficient heat in a minimal amount of time • Controllable braze flow through the use of braze rings • Even distribution of heating
