Brazing is a popular method for joining metals, but it comes with its own set of challenges.
4 Disadvantages of Brazing
1. Weak Joint Compared to Welding
Brazed joints are generally not as strong as welded joints.
The strength of a brazed joint depends on the strength of the brazing filler metal used.
It is typically weaker than the base metal being joined.
2. Aesthetic Disadvantage
The color of the joint created by brazing is often different from that of the base metal.
This can create an aesthetic disadvantage, especially in applications where the appearance of the joint is important.
3. Potential Off-Gassing of Metallic Elements
Some base metals and brazing filler metals used in brazing may contain elements such as cadmium, zinc, or lead.
When heated to brazing temperatures, these elements can give off gases that can contaminate the brazing furnace and increase the void content of the brazed joint.
4. Close Fits Required for Capillary Action
Brazing relies on capillary action to draw the molten filler metal into the joint.
This requires the metal to be joined to be very close together.
If there is a gap or large clearance between the metal surfaces, capillary action may not be sufficient to create a strong joint.
