Under optimal conditions of the process the temperatures experienced by a copper work piece in fusion welding, brazing and soldering are such that

$${T_{welding}}\, > \,{T_{soldering}}\, > \,{T_{brazing}}$$

$${T_{soldering}}\, > \,{T_{welding}}\, > \,{T_{brazing}}$$

$${T_{brazing}}\, > \,{T_{welding}}\, > \,{T_{soldering}}$$

$${T_{welding}}\, > \,{T_{brazing}}\, > \,{T_{soldering}}$$
