orbital welding ppt free download

Orbital welding first found use in the 1960’s when the aerospace industry recognized the need for a superior joining technique for aircraft hydrolic lines. The solution: a mechanism to rotate a welding arc from a tungsten electrode around a tube-weld joint. Regulating weld current with a control system automated the entire process. The result was a more precise, reliable method than manual welding.

Purpose

To provide leak proof joint between Tube to Tube sheet in Condenser in addition to Forced expansion.
