Brazing is the metal joining process in which the temperature used is above 450 deg C but less than the melting point of metals. Brazing is one of the widely used manufacturing processes because it provides strong joints, ductile joints, ease of operation, suited to dissimilar metals, requires low temperatures, economical, and highly adaptable to automation.
Following are the top 10 reasons why the brazing is the versatile metal joining process.
1. Brazing is economical. The cost per- joint compares quite favourably with joints made by other metal joining methods.
2. Brazed joints are ductile, able to withstand considerable shock and vibration.
3. On nonferrous metals and steels, the tensile strength of a properly made joint will often exceed that of the metals joined.
4. Brazed joints are usually easy and rapidly made, with operator skill readily acquired.
5. On stainless steels, it is possible to develop a joint whose tensile strength is 130,000 pounds per square inch.
6. Brazing is ideally suited to the joining of dissimilar metals. You can easily join assemblies that combine ferrous with nonferrous metals, and metals with widely varying melting points.
7. Brazing is essentially a one-operation process. There is seldom any need for grinding, filing or mechanical finishing after the joint is completed.
8. Brazing is performed at relatively low temperatures, reducing the possibility of warping, overheating or melting the metals being joined.
9. Brazing is highly adaptable to automated methods.
10. The flexibility of the brazing process enables you to match your production techniques close to manufacturing requirements.
