Friction Welding and Inertia Welding -
History
The first proposed use of friction in welding was perhaps contained in the American Patent of 1891 when frictional heat was proposed to join a tube to a V-shaped die. Friction Welding was put to commercial use first in Russia around 1956-57 due to the efforts of A.I. Chudikov.
The process was introduced to the west in 1959. - In 1965, a U.S. Patent was granted to T.L. Obrele, M.R. Claton, C.D. Lloyd and C.F. White and assigned to the Caterpillar Tract or Company for the Inertia Welding Process.
