Induction Brazing Aluminum to Aluminum Tube

Objective Induction brazing of two aluminum pipes

Equipment DW-UHF-6KW-III handheld induction brazing heater Materials Аluminum to aluminum tube Flared at interface 0.25” (6.35mm) Brazed to steel tube 0.19” OD (4.82mm) Power: 6kW Temperature: 1600°F (871°C) Time: 3sec

Results and Conclusions: Induction heating provides:

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

Induction Brazing T Shaped Copper Tubing Assemblies

High Frequency Induction Brazing T Shaped Copper Tubing Assemblies

Objective: Test 1 – Induction brazing T-shaped copper tubing assemblies – 3 joints simultaneously Test 2 – Induction brazing copper tubing Industry: HVAC Materials: Copper tubers  6, 8, 10, 12 mm ( 0¹⁵⁄_64, 0⁵⁄_16, 0²⁵_⁄64, 0¹⁵_⁄32inch. ); thickness: 1 mm ( 0³⁄₆₄ inch.) Alloy: Cu-P-Ag rings TIP: The use of alloy rings is highly recommended with a hand-held brazing gun.

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.

induction brazing and soldering technology

HLQ Induction heating systems are value added systems that can fit directly into the manufacturing cell, reducing scrap, waste, and without the need for torches. The systems can be configured for manual control, semi-automated, and all the way up to fully automated systems. HLQ induction brazing and soldering systems repeatedly provide clean, leak-free joints for a wide range of parts including fuel lines, heat exchangers, gas distributors, manifolds, carbide tooling, and more. Principles of Induction Brazing & Soldering Brazing and soldering are processes of joining similar or dissimilar materials using a compatible a filler material. Filler metals include lead, tin, copper, silver, nickel and their alloys. Only the alloy melts and solidifies during these processes to join the work piece base materials. The filler metal is pulled into the joint by capillary action. Soldering processes are conducted below 840°F (450°C) while brazing applications are conducted at temperatures above 840°F (450°C) up to 2100°F (1150°C). The success of these processes depends upon the assembly’s design, clearance between the surfaces to be joined, cleanliness, process control and the correct selection of equipment needed to perform a repeatable process. Cleanliness is ordinarily obtained by introducing a flux which covers and dissolves dirt or oxides displacing them from the braze joint. Induction Brazing Filler Materials Induction Brazing filler metals can come in a variety of forms, shapes, sizes and alloys depending on their intended use. Ribbon, preformed rings, paste, wire and preformed washers are just a few of the shapes and forms alloys that can be found. The decision to use a particular alloy and/or shape is largely dependent on the parent materials to be joined, placement during processing and the service environment for which the final product is intended. Many operations are now conducted in a controlled atmosphere with a blanket of inert gas or combination of inert / active gasses to shield the operation and eliminate the need for a flux. These methods have been proven on a wide variety of material and part configurations replacing or complimenting atmosphere furnace technology with a just in time - single piece flow process. Clearance Affects Strength Clearance between the faying surfaces to be joined determines the amount of braze alloy, capillary action / penetration of the alloy and subsequently the strength of the finished joint. The best fit up condition for conventional silver brazing applications are 0.002 inches (0.050 mm) to 0.005 inches (0.127 mm) total clearance. Aluminum is typically 0.004 inches (0.102 mm) to 0.006 inches (0.153 mm). Larger clearances up to 0.015 inches (0.380 mm) usually lack sufficient capillary action for a successful braze. Brazing with copper (above 1650°F / 900°C) requires the joint tolerance kept to an absolute minimum and in some cases press fit at ambient temperatures to assure minimum joint tolerances while at the brazing temperature. Induction heating has proven to be a valuable aid in the joining process for many reasons. Rapid heading and precise heat control offers the possibility of localized heating of high strength components without significantly changing the material properties. It also allows for the brazing of difficult materials such as aluminum and sequential, multi-alloy brazing and soldering of close proximity joints. Induction heating in brazing and soldering applications is readily adaptable to production line methods, permitting strategic arrangement of the equipment in an assembly line, and if necessary, heating by remote control. Frequently, induction brazing and soldering permits a reduction in the require number of part fixtures, with the minimal heating of the fixtures increasing life span and maintaining accuracy in alignment of the components to be joined. Since operators need not guide the induction heating source, both hands are left free to prepare assemblies for joining. HLQ induction brazing equipment delivers quality, consistency, configurable throughput, and quick change-over tooling for various production needs.
