What is Induction heat Dismounting?

induction dismounting gearwheel from shaft

What is Induction Heat Dismounting and How Does it Work? Induction heat dismounting is a non-destructive method of removing gears, couplings,gearwheels,bearings, motors,stators,rotors and other mechanical parts from shafts and housings. The process involves heating the part to be removed using an induction coil, which generates an electromagnetic field. The electromagnetic field induces eddy currents in … Read more

Why Induction Preheating is Essential for Welding

Why Induction Preheating is Essential for Welding: Benefits and Techniques. Induction preheating is a process in which an electrically conductive material is heated by inducing an electrical current in it. The heat is produced by the resistance of the material to the current flow. Induction preheating is widely used in the welding industry for enhancing … Read more

Induction Wire and Cable Heating

Induction wire and cable heater is also used for the induction preheating, post heating or annealing of metallic wire along with the bonding/vulcanization of insulating or shielding within various cable products. Preheating applications can include heating wire prior to drawing it down or extruding. Post heating would typically include processes such a bonding, vulcanizing, curing … Read more

induction curing

What is induction curing? How does induction curing work? Simply put, line power is converted to alternating current and delivered to a work coil which creates an electromagnetic field within the coil. The piece with the epoxyĀ on it can be metal or a semiconductor such as carbon or graphite. To cure epoxy on non-conductive substrates … Read more

Induction Heat Treating Surface Process

What is induction heat treating surface process? Induction heating is a heat treating process that allows very targeted heating of metals by electromagnetic induction. The process relies on induced electrical currents within the material to produce heat and is the preferred method used to bond, harden or soften metals or other conductive materials. In modern … Read more

Induction Hardening Surface Process

Induction Hardening Surface Process Applicatons What is induction hardening ? Induction hardening is a form of heat treatment in which a metal part with sufficient carbon content is heated in the induction field and then rapidly cooled. This increases both the hardness and brittleness of the part.Ā Induction heatingĀ allows you to have localized heating to a … Read more

HLQ induction brazing and soldering systems repeatedly provide clean, leak-free joints for … Read more

Induction Brazing Basics

Induction Brazing Basics for jointing copper,silver,brazing,steel and stainless steel,etc.

Induction Brazing uses heat and filler metal to join metals.Ā Once melted, the filler flows between close-fittingĀ base metals (the pieces being joined) by capillaryĀ action. The molten filler interacts with a thin layerĀ of the base metal to form a strong, leak-proof joint.Ā Different heat sources can be used for brazing:Ā induction and resistance heaters, ovens, furnaces,Ā torches, etc. There are three common brazingĀ methods: capillary, notch and moulding. InductionĀ brazing is concerned solely with the first of these.Ā Having the correct gap between the base metals isĀ crucial. A too-large gap can minimize the capillaryĀ force and lead to weak joints and porosity. ThermalĀ expansion means gaps have to be calculated forĀ metalsĀ at brazing, not room, temperatures. OptimumĀ spacing is typically 0.05 mm ā€“ 0.1 mm.Ā Before you brazeĀ Brazing is hassle-free. But some questions shouldĀ be investigated ā€” and answered ā€” in order to assureĀ successful, cost-effective joining. For instance: HowĀ suitable are the base metals for brazing; whatā€™sĀ the best coil design for specific time and quality demands;Ā should the brazing be manual or automatic?

brazing material
AtĀ DAWEI Induction we answer these and otherĀ key points before suggesting a brazing solution.Ā Focus on fluxĀ Base metals must usually be coated with a solventĀ known as flux before they are brazed. Flux cleansĀ the base metals, prevents new oxidation, and wetsĀ the brazing area prior to brazing. It is crucial to applyĀ sufficient flux; too little and the flux may become
saturated with oxides and lose its ability to protectĀ the base metals.Ā Flux is not always needed. Phosphorous-bearing filler
can be used to braze copper alloys, brass and bronze.Ā Flux-free brazing is also possible with active atmospheresĀ and vacuums, but the brazing must then beĀ performed in a controlled atmosphere chamber.Ā Flux must normally be removed from the part onceĀ the metal filler has solidified. Different removalĀ methods are used, the most common being waterĀ quenching, pickling and wire brushing.
