There are certain factors which determine a brazing joint's strength which are mainly :

• Joining of the base metals
• Joint clearance
• Usage of filler metal
• Use of varied base & filler metals
• The gap between the two metals when being joined
• Whenever there is an increment in the gap, it leads to an automatic decrement in the joint strength. But at times, the braze joint strength will equal or surpass the the strength of the base metals when used in proper conditions.
