Why choose Induction Brazing?

Why choose Induction Brazing?

Induction heating technology is steadily displacing open flames and ovens as the preferredĀ heat source in brazing. Seven key reasons explain this growing popularity:

1. Speedier solution
Induction heating transfers more energy per squareĀ millimeter than an open flame. Put simply, inductionĀ can braze more parts per hour than alternativeĀ processes.
2. Quicker throughput
Induction is ideal for in-line integration. Batches ofĀ parts no longer have to be taken aside or sent outĀ for brazing. Electronic controls and customized coilsĀ let us integrate the brazing process into seamlessĀ production processes.
3. Consistent performance
Induction heating is controllable and repeatable. EnterĀ your desired process parameters into the inductionĀ equipment, and it will repeat heating cycles with onlyĀ negligible deviations.

4. Unique controllability

Induction lets operators view the brazing process,Ā something that is difficult with flames. This and preciseĀ heating minimize the risk of overheating, whichĀ causes weak joints.
5. More productive environment
Open flames create uncomfortable working environments.Ā Operator morale and productivity suffer asĀ a result. Induction is silent. And there is virtually noĀ increase in ambient temperature.
6. Put your space to work
DAWEIĀ Induction brazing equipment has a small footprint.Ā Induction stations slot easily into productionĀ cells and existing layouts. And our compact, mobileĀ systems let you work on hard-to-access parts.
7. No-contact process
Induction produces heat within the base metals ā€”Ā and nowhere else. Itā€™s a no-contact process; theĀ base metals never come into contact with flames.Ā This protects the base metals from warping, which inĀ turn increases yield and product quality.

What is induction welding?

What is induction welding?
With induction welding the heat is electromagneticallyĀ induced in the workpiece. The speed and accuracy
of induction welding make it ideal for edge welding ofĀ tubes and pipes. In this process, pipes pass an inductionĀ coil at high speed. As they do so, their edges areĀ heated then squeezed together to form a longitudinalĀ weld seam. Induction welding is particularly suitableĀ for high-volume production. Induction welders canĀ also be fitted with contact heads, turning them into
dual purpose welding systems.
What are the benefits?
Automated induction longitudinal welding is a reliable,Ā high-throughput process. The low power consumptionĀ and high efficiency of DAWEIĀ Induction welding systemsĀ reduce costs. Their controllability and repeatability minimizeĀ scrap. Our systems are also flexibleā€”automaticĀ load matching ensures full output power across a wideĀ range of tube sizes. And their small footprints makeĀ them easy to integrate or retrofit into production lines.
Where is it used?
Induction welding is used in the tube and pipe industryĀ for the longitudinal welding of stainless steel (magneticĀ and non-magnetic), aluminum, low-carbon and highstrengthĀ low-alloy (HSLA) steels and many other conductive
materials.

What is induction bonding?

What is induction bonding?
Induction bonding uses induction heating to cureĀ bonding adhesives. Induction is the main method forĀ curing adhesives and sealants for car componentsĀ such as doors, hoods, fenders, rearview mirrors andĀ magnets. Induction also cures the adhesives in composite-Ā to-metal and carbon fiber-to-carbon fiber joints.Ā There are two main types of automotive bonding: spotbonding,
which heats small segments of the materialsĀ to be joined; full-ring bonding, which heats completeĀ joints.
What are the benefits?
DAWEIĀ Induction spot bonding systems ensure preciseĀ energy inputs for each panel. Small heat affected zonesĀ minimize total panel elongation. Clamping is notĀ needed when bonding steel panels, which reducesĀ stresses and distortion. Each panel is electronicallyĀ monitored to ensure that energy input deviations areĀ within tolerances. With full-ring bonding, a one-sizefits-
all coil reduces the need for spare coils.
Where is it used?
Induction is the preferred bonding method in the automotiveĀ industry. Widely used to bond steel and aluminumĀ sheet metal, induction is increasingly employedĀ to bond new lightweight composite and carbon fiberĀ materials. Induction is used to bond curved strands,Ā brake shoes and magnets in the electrotechnical industry.
It is also used for guides, rails, shelves andĀ panels in the white goods sector.
What equipment is available?
DAWEIĀ Induction is theĀ professionalĀ induction curingĀ specialist. In fact, we invented induction spot curing.
The equipment we deliver ranges fromĀ individual system elements such as power sourcesĀ and coils, to complete and fully supported turn-keyĀ solutions.

What is induction tempering?

What is induction tempering?

Induction tempering is a heating process that optimizesĀ mechanical properties such as toughness and ductility
in workpieces that have already been hardened.
What are the benefits?
The main advantage of induction over furnace temperingĀ is speed. Induction can temper workpieces inĀ minutes, sometimes even seconds. Furnaces typicallyĀ take hours. And as induction tempering is perfect forĀ inline integration, it minimizes the number of componentsĀ in process. Induction tempering facilitates qualityĀ control of individual workpieces. Integrated inductionĀ temper stations also save valuable floor space.
Where is it used?
Induction tempering is widely employed in the automotiveĀ industry to temper surface-hardened componentsĀ such as shafts, bars and joints. The process is alsoĀ used in the tube and pipe industry to temper throughhardenedĀ workpieces. Induction tempering is sometimesĀ performed in the hardening station, sometimesĀ in one or several separate temper stations.
What equipment is available?
Complete HardLine systems are ideal for many temperingĀ applications. The chief benefit of such systemsĀ is that hardening and tempering are performed byĀ one machine. This delivers significant time and costĀ savings in a small footprint compared to alternativeĀ technologies. With furnaces, for example, one furnaceĀ often first hardens the workpieces, with a separate furnace
then being used for tempering. Solid stateĀ DAWEIĀ Induction HeatingĀ Systems are also used forĀ tempering applications.

What is Induction Brazing?

What is Induction Brazing?

Induction Brazing is a materials-joining process that uses a filler metal (and usually an anti-oxidizing solvent called flux) to join two pieces of close-fitting metal together without melting the base materials. Instead, induced heat melts the filler, which is then drawn into the base materials by capillary action.

What are the benefits?

Induction brazing can join a wide range of metals, even ferrous to non-ferrous. Induction brazing is precise and quick. Only narrowly defined areas are heated, leaving adjacent areas and materials unaffected. Correctly brazed joints are strong, leak-proof and corrosion resistant. They are also very neat, usually requiring no further milling, grinding or finishing. Induction brazing is ideal for integrating into production lines.

Where is it used?

DaWei Induction brazing systems can be used for virtually any brazing task. To date, our systems are typically used in the electrotechnical industry to braze generator and transfomer components like bars, strands, rings, wires and SC-rings. They also braze fuel pipes and AC and brake parts for the automotive industry. The aeronautics sector uses induction to braze fan blades, blades for casings, and fuel and hydraulic systems.
