1946-1965
Under the direction of the founder's son, who is also an A & C engineer, the company continues to develop and diversify itself and, in 1962, creates a small subsidiary, half owned by SAF (Soudure Autogène Française) and Ateliers De La Chaînette, whose vocation is the study and realization of welding machines and oxycutting.
This activity will continue before being abandoned in the late 1980s.
Ateliers De la Chaînette also build their first lifting equipment.
