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. Once melted, the filler flows between close-fitting base metals (the pieces being joined) by capillary action. The molten filler interacts with a thin layer of the base metal to form a strong, leak-proof joint. Different heat sources can be used for brazing: induction and resistance heaters, ovens, furnaces, torches, etc. There are three common brazing methods: capillary, notch and moulding. Induction brazing is concerned solely with the first of these. Having the correct gap between the base metals is crucial. A too-large gap can minimize the capillary force and lead to weak joints and porosity. Thermal expansion means gaps have to be calculated for metals at brazing, not room, temperatures. Optimum spacing is typically 0.05 mm – 0.1 mm. Before you braze Brazing is hassle-free. But some questions should be investigated — and answered — in order to assure successful, cost-effective joining. For instance: How suitable are the base metals for brazing; what’s the best coil design for specific time and quality demands; should the brazing be manual or automatic? At DAWEI Induction we answer these and other key points before suggesting a brazing solution. Focus on flux Base metals must usually be coated with a solvent known as flux before they are brazed. Flux cleans the base metals, prevents new oxidation, and wets the brazing area prior to brazing. It is crucial to apply sufficient flux; too little and the flux may become saturated with oxides and lose its ability to protect the base metals. Flux is not always needed. Phosphorous-bearing filler can be used to braze copper alloys, brass and bronze. Flux-free brazing is also possible with active atmospheres and vacuums, but the brazing must then be performed in a controlled atmosphere chamber. Flux must normally be removed from the part once the metal filler has solidified. Different removal methods are used, the most common being water quenching, pickling and wire brushing.   https://dw-inductionheater.com/induction-brazing-basics.html?feed_id=243828&_unique_id=663150791ff90

Equipment: DW-UHF-20kw induction brazing machine Power: Test 1 ( 7-8kW ) Test 2 ( 6.5-9.2kW ) Time: 8 secs. Coil: Regular induction heating coil. Custom coil design is possible upon request. The Process: We successfully carried out two induction brazing tests with several copper assemblies.  First, Cu-P-Ag alloy rings were placed around the thinner of the copper tubings. No additional flux was needed.  The pipes were then carefully aligned. The process of induction brazing was initiated. Once the induction brazing was complete, the two samples were submerged in cold water in order to be cooled instantly. The excessive amount of flux can be furtherly cleaned.

High Frequency Induction Brazing Steel Tube to Copper Tube

Objective The goal is to braze a steel tube to a copper tube in 60 seconds using flux and brazing alloy.

Equipment DW-UHF-10kw induction brazing heater Three turns dual diameter coil Materials • Steel tube and copper receiver • Braze alloy (CDA 681) • B-1 flux Key Parameters Temperature: Approximately 1750° F (954° C) Frequency: 148 kHz

Process:

1. The assembly section was pre-assembled and fluxed (B-1) then located in the two diameter coil with a single pre-formed alloy ring set at the interface area.
2. Alloy flow and joint completed in 60 seconds.
3. The material was cooled in water following the completion of induction brazing.
4. The joint was then cross-sectioned to validate that the brazing process had produced a strong, high quality joint.

Results/Benefits:

• Strong durable joints with induction heating
• Selective and precise heat zone, resulting in less part distortion and joint stress than welding
• Less oxidation
• Faster heating cycles
• More consistent results and suitability for large volume production, without the need for batch processing
• Safer than flame brazing

Induction Brazing Carbon Steel Filter

High Frequency Induction Brazing Carbon Steel Filter

Objective: A customer from the automotive industry is looking for a semi-automatic induction process to braze the gas filters components for very high production volumes. The customer is looking to evaluate induction brazing of pegs into a gas filter cap. There are two separate braze joints on either end of the filter. The heat cycle must be 5 seconds per joint, and the duty cycle has to be continuous. Industry: Automotive & Transportation Induction Heating Equipment: In this application test, the engineers used DW-UHF-6kW-III Induction Heater with water-cooled Heat Station. Induction Heating Process: The test was taken by brazing this tabbed joint from the inside. This works great and is much quicker since the operator doesn’t have to wait for the heat to penetrate through. The technical settings of a power supply were 5kW of power, 1300°F (704.44°C) of temperature, and the reached heat cycle time was 3 seconds. There is currently a washer between the filter body and the tab. We recommend the washer and tab were merged into one part. It would be much easier for the process of induction brazing. Benefits: The integration of induction brazing will increase repeatability, productivity, and will improve energy efficiency. With induction heating equipment there is more control over the process and low maintenance requirements. https://dw-inductionheater.com/product/induction-brazing-carbon-steel-filter?feed_id=142060&_unique_id=62de5771017cc
