(wɛldɪŋ)
noun
(Mechanical engineering: Manufacturing and assembly)
Welding is the process of joining two plastic or metal parts by melting them, with or without using a further molten material.
The heat produced by an arc is used in welding to melt metal rods, which solidify to provide a strong joint between two metal surfaces.
Special helmets must be worn when doing welding to protect the eyes.
Welding is the process of joining two plastic or metal parts by melting them, with or withoutusing a further molten material.

Related wordsCompare welding with spot-weld, which is to join two pieces of metal by melting small circular areas on the metalusing heat from an electric current and pressure.
