Brazing Vs Welding

Following are the differences between brazing and welding.

(i)  In brazing, the joint surfaces are not raised to fusion point (or melted) and the joint is produced by the solidification and adhesion of a thin layer of molten filler metal spread between the mating surfaces. In welding, the two surfaces to be joined are always heated to molten state for making a joint.

(ii) The filler metal in brazing spreads between the joint by capillary action. In welding, the molten filler rod solidifies at the same place where it melts.

(iii)In brazing, there is no penetration of the filler metal into base metal whereas in welding it is there.

Brazing as a production process has certain limitations in its application. It calls for a properly machined fitting in making parts to be joined for proper capillary action. Limitation on the size of components to be brazed is there as in the process outer area of the joint is to be heated. Large components, therefore, cannot be heated properly to brazing temperature. Brazed joints develop corrosion is flux is not properly removed. Brazing  needs  certain  degree  of  skill  and  experience  on  the  part  of  the  welder  for handling special brazing jobs.
