Harchris was established by Harry Preston in 1950 as Central Welding Works – a general engineering company.

In 1951 we moved to Era, Springs and still occupy the original premises.

Heat treatment became more popular in the 1960′s as a concept to reduce stress originating from welding. As stress relieving became more common, so did hardening and tempering and a host of other processes.
