Electroslag Welding: Definition, Working Principle
The process of electro slag welding can be made semi-automatic which may help in faster welding of the workpiece. Minimum slag: Slag is the waste product generated during the process of welding. Slag may weaken the welding areas. Electroslag welding promotes low slag deposition than traditional welding methods.

Ultrasonic testing
Ultrasonic testing (UT) is a family of non-destructive testing techniques based on the propagation of ultrasonic waves in the object or material tested. In most common UT applications, very short ultrasonic pulse-waves with center frequencies ranging from 0.1-15 MHz, and occasionally up to 50 MHz, are transmitted into materials to detect internal flaws or to characterize materials.
