________ inert gas welding is popular for workpieces with great detail as it is known for its precision.

________ inert gas welding robots are ideal for working with thick metals as filler wire is used to join workpieces together.

______ arc welding is a precision welding method, but unlike TIG it can be used for both thin and thick metals. During welding, inert gas is converted into plasma to heat and melt metals.

__________ welding involves using a beam of high velocity electrons.

___________ welding uses ultrasonic vibrations to melt and join workpieces.
