Micro plasma

Keyhole plasm

Mega plasma

Ionised plasma

avoids crack in the joint

increase the strength of flux coating

reduce time required to complete the weld

easily conduct electricity through electrode

The process essentially requires a vacuum

The process essentially requires a filler wire

Highly reactive metals can be welded using the process

The cost of EBW equipment is comparatively higher with respect to other arc welding processes
