Soldering is a process in which two or more metal items are joined together by melting and flowing a filler metal (solder) into the joint, the filler metal having a lower melting point than the adjoining metal. Soldering differs from welding in that soldering does not involve melting the work pieces. In brazing, the filler metal melts at a higher temperature, but the work piece metal does not melt. In the past, nearly all solders contained lead, but environmental concerns have increasingly dictated use of lead-free alloys for electronics and plumbing purposes. " C6 m" j$ S, z1 a: v4 Q
Welding is a fabrication or sculptural process that joins materials, usually metals or thermoplastics, by causing coalescence. This is often done by melting the workpieces and adding a filler material to form a pool of molten material (the weld pool) that cools to become a strong joint, with pressure sometimes used in conjunction with heat, or by itself, to produce the weld. This is in contrast with soldering and brazing, which involve melting a lower-melting-point material between the workpieces to form a bond between them, without melting the work pieces

% T8 u/ g5 b: Q9 l# J简单说weld是指通过将两块金属的边缘熔化使其整合在一起，而solder是指通过一小块熔化的软金属将两块独立的金属连在一起。也就是说，相比于weld，solder需要一小块额外的金属来完成焊接 2 O* l# `& k7 ^5 Q U/ Y
