DSP Digital Control Pannel Induction Brazing Machine For Stainess Steel To Brass
Induction Brazing Machine
Induction Brazing is a method of joining two pieces of metal together with a third, molten filler metal. The joint area is heated above the melting point of the filler metal but below the melting point of the metals being joined; the molten filler metal flows into the gap between the other two metal pieces by capillary action and forms a strong metallurgical bond as it cools. Of all the methods available for metal joining, induction brazing may be the most versatile. Brazed joints have great tensile strength – they are often stronger than the two metals being bonded together. Brazed joints repel gas and liquid, withstand vibration and shock and are unaffected by normal changes in temperature. Because the metals being joined are not themselves melted, they are not warped or otherwise distorted and retain their original metallurgical characteristics. Because brazed joints have a very clean, well-finished appearance, induction brazing often is the preferred bonding process for manufacturing plumbing fixtures, tools, heavy construction equipment and high-quality consumer products. The process is well-suited for joining dissimilar metals, which gives the assembly designer more material options. Complex assemblies can be manufactured in stages by using filler metals with progressively lower melting points. Induction Brazing is relatively fast and economical, requires relatively low temperatures and is highly adaptable to automation and lean manufacturing initiatives.

ADVANTAGES OF THE INDUCTION BRAZING MACHINE
Induction Brazing In addition to the general benefits induction heating brings to virtually any heating process, there are very specific reasons to use induction heating for industrial brazing. These include selective heating, better joint quality, reduced oxidation and acid cleaning, faster heating cycles and more consistent results.
• SELECTIVE HEATING
Induction heating can be targeted to provide heat to very small areas within tight production tolerances. Only those areas of the part within close proximity to the joint are heated; the rest of the part is not affected. Since there is no direct contact with the part, there is no opportunity for breakage. The life of the fixturing is substantially increased because problems due to repeated exposure to heat (such as distortion and metal fatigue) are eliminated. This advantage becomes particularly important with high-temperature brazing processes. With efficient coil design, careful fixturing and consistent part placement, it is possible to simultaneously provide heat in different areas of the same part.
• BETTER QUALITY JOINTS
Induction heating produces clean, leakproof joints by preventing the filler from flowing into areas that it shouldn’t. This ability to create clean and controllable joints is one of the reasons that induction brazing is being used extensively for high-precision, high-reliability applications.
• REDUCED OXIDATION AND CLEANING
Flame heating in a normal atmosphere causes oxidation, scaling and carbon build up on the parts. To clean the parts, applications of joint-weakening flux and expensive acid cleaning baths have traditionally been required. Batch vacuum furnaces solve these problems, but have significant limitations of their own because of their large size, poor efficiency and lack of quality control. Brazing with induction reduces both oxidation and costly cleaning requirements, especially when a rapid cool-down cycle is used.
• FAST HEATING CYCLES
Because the induction heating cycle is very short in comparison to flame brazing, more parts can be processed in the same amount of time, and less heat is released to the surrounding environment.
• CONSISTENT RESULTS
Induction brazing is a very repeatable process because variables such as time, temperature, alloy, fixturing, and part positioning are very controllable. The internal power supply of the RF power supply can be used to control cycle time, and temperature control can be accomplished with pyrometers, visual temperature sensors or thermocouples.
TYPES OF BRAZE JOINTS
Although there are a wide variety of braze joints to suit varying part and assembly geometries and functions, most braze joints are variations of one of two basic types – the butt joint and the lap joint. To form a butt joint, the two pieces of metal are positioned in an edge to edge, in an end-to-end arrangement as shown on following picture. The strength of the bond depends to a large extent on the amount of bonding surface, but a properly formed butt joint will be strong enough to meet many application needs. The setup is relatively simple, and for some applications, it may be an advantage to have a consistent part thickness at the joint.
For applications which require a stronger bond, an alternative type of joint may be preferable. Lap joints have a larger bonding surface because the two metals overlap each other. Therefore a stronger bond is produced. Lap joints do have a double thickness in the joint area, which may be a potential problem for applications where space is restricted. But for plumbing fixtures and similar applications, this is not a problem. The overlapping nature of the lap joint actually assists in positioning the parts for brazing; particularly with tubular parts, the joint becomes self-supporting because one part fits into the other.
The advantages of both basic joint types are combined in a butt-lap joint. Although this type of joint requires more work to assemble, it has both a single thickness and maximum strength, and is usually self-supporting
