Abstract
The invention provides a method of assembling together two thin plane parts () by friction welding. A main sheet () made of a material having high thermal conductivity is held against the parts () for assembly. The main sheet () picks up the heat induced by the friction of a welding pin () against the parts () for the purpose of forming the weld bead (), and it dissipates this heat by radiation. Temperature regulation of the welding operation is obtained by the main sheet (), ensuring that no localized excess heating occurs in the welding zone. The main sheet () is based on copper and presents a thickness that is less than the thickness of the parts ().
