Brazing Guide
Your Online Brazing Resource
Introduction
Brazing is a method of joining two pieces of metal together with a third, molten filler metal. Of all the methods available for metal joining, brazing may be the most versatile. The process is relatively fast and economical, requires relatively low temperatures and is highly adaptable to automation and lean manufacturing initiatives.
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 to be joined are not themselves melted, they are not warped or otherwise distorted and retain their original metallurgical characteristics.
Use The Brazing Guide to learn about the different aspects of brazing and the many advantages offered by this unique process.
Contents
Brazing Overview ......Topics include brazing basic definitions and when brazing works best. This overview also covers the various heat sources for brazing – torch heating, furnace heating, and induction heating. The three common types of braze joints are also described.
Basic Brazing Procedures ......Reviews how to determine the joint spacing, choose the right alloy, eliminate grease and contaminants, add flux or use protective atmosphere, position parts carefully, turn on the heat, and clean the joint if needed.
Induction Brazing ......Explains how induction heating can be utilized to produce clean, consistent braze joints. Reasons to use induction heating for industrial brazing. include selective heating, better joint quality, reduced oxidation and acid cleaning, faster heating cycles and more consistent results.
Types of Brazing Atmospheres ......The induction brazing process can be carried out in three different environments, each with its own advantages and disadvantages: open air; a controlled atmosphere of argon or other inert gas; or a high vacuum/high pressure environment. This section discusses the relative merits of each type.
Suggested Brazing Atmospheres ......What's the best filler metal for brazing stainless steel? What's the best atmosphere for brazing copper with silver? Our Selection Guide gives you the answers! .
Choosing An Alloy ......Copper, nickel and silver and the most frequently-used base metals for brazing alloys; aluminum and gold are also used for specific purposes. This section compares important characteristics and advantages of the most commonly used base metals.
