Brazing, soldering and Adhesives Brazing: Brazing is a Multi metal part joining process in which we heated the metal, convert it to liquid and then move it with the help of capillary action to join them. In brazing, the metal formed is stronger than the individual parts. This occur because of three reasons 1.  Because of small part clearance 2.  The metallurgical bonding and 3.  The geometric construction that is imposed on Bonding Like welding, brazing is also metals parts joining process but it has some advantage over the welding, some of them are 1.  Any metal parts can be joined 2.  Less time consuming and 3.  Some methods are useful for multiple parts joining having different geometries 4.  Brazing can applied to those parts that have a very thin diameter, welding cannot do that for us. 5.  Less heat is needed for Brazing as compared to Welding. Some of the disadvantage of Brazing is 1.  Welded joint are more stronger then brazed metal 2.  Higher service temperature may weaken the
