Question

why did the solde decide to make a move from the battle field​

Answer 1

Since non-eutectic solder alloys have a small plastic range, the joint must not be moved until the solder has cooled down ...

Answer 2

☯️It is a process in which two or more items are joined together by melting and putting a filler metal (solder) into the joint, the filler metal having a lower melting point than the adjoining metal.

☯️Unlike welding, soldering does not involve melting the work pieces.

☯️In brazing, the work piece metal also does not melt, but the filler metal is one that melts at a higher temperature than in soldering.

☯️In the past, nearly all solders contained lead, but environmental and health concerns have increasingly dictated use of lead-free alloys for electronics and plumbing purposes.
