   • Soft soldering is the process of joining two pieces using heat and a filler material.
     • Brazing is performed at relatively low temperatures, this reduces the possibility of the metals being joined becoming deformed, overheating, or melting.
       • Resistance welding is a thermoelectric process in which heat is generated at the interface of the parts to be joined.
     • Arc welding is one of the fusion processes for joining metals through the application of intense heat.
   • It is a joining process in which fuel gas and oxygen are used to produce a flame that melts the ends of the piece and with or without application of filler material.
