Welding Efficiency

Arc Efficiency Of Plasma Arc Welding
Arc efficiency is measured calorimet- rically, which requires special equipment and is not usually done. Arc efficiencies of 50 to 70% are commonly encountered in arc welding, but can range higher for such efficient processes as submerged arc welding (Ref. 1). Melting efficiency, qm, is the fraction ...

Blisk - Wikipedia
A blisk (portmanteau of bladed disk) is a turbomachine component comprising both rotor disk and blades. It consists of a single part, instead of an assembly of a disk and individual, removable blades. Blisks may be additive manufactured, integrally cast, machined from a solid piece of material, or made by welding individual blades to a rotor disk. ... Read Article
