1.)BACKHAND WELDING – A welding technique in which the welding
torch or gun is directed opposite to the progress of welding.
2.)BACK WELD – A weld deposited at the back of a single groove weld.
3.)COLD WELDING – A solid state welding process in which pressure is applied at room temperature to produce coalescence of metals with substantial deformation at the weld.
4.)DEPTH OF FUSION – Distance that fusion extends into the base metal or previous pass from the surface melted during welding.
5.)DIFFUSION WELDING – A solid state welding process that produces coalescence of the faying surfaces by the application of pressure at elevated temperature.
6.)ELECTRO SLAG WELDING – A welding process producing coalescence of metals with molten slag that melts the filler metal and the surfaces of the workpieces. The weld pool is shielded by slag.
7.)FILLER METAL – Metal to be added in making a welded, brazed or soldered joint.
8.)FUSION ZONE – Area of base metal melted as determined on the crosssection of a weld.
9.)POST HEATING – Application of heat to an assembly after a welding,brazing, soldering, thermal spraying or thermal cutting.
10.)PRE HEATING – Application of heat to the base metal immediately before
welding, brazing, soldering, thermal spraying and cutting.
