Electroslag and electrogas welding (ESW/EGW) are closely related
processes (Figs. 3.12 and 3.13) that offer high-deposition welding in
the vertical plane. Properly applied, these processes offer significant
savings over alternative out-of-position methods and, in many cases,
savings over flat position welding. Although the two processes have
similar applications and mechanical setup, there are fundamental dif-
ferences in the arc characteristics. Electroslag and electrogas are
