WASHINGTON â The Supreme Court openly struggled Wednesday with the racial preferences used by the University of Texas to achieve student diversity, as several conservative justices questioned how much is enough to declare affirmative action programs no longer necessary.
Gas metal arc welding (GMAW), also known as metal inert gas or MIG welding, is a semi-automatic or automatic process that uses a continuous wire feed as an electrode and an inert or semi-inert gas mixture to protect the weld from contamination.
MIG welding is an acronym for Metal Inert Gas Welding. This process is sometimes also referred to as Gas Metal Arc Welding (GMAW). MIG Welding is used for aluminum as well as other metals and can be automatic or semi-automatic. MIG Welding uses a wire that is connected to a direct current source which acts as an electrode and combines two pieces of metal through continuous flow by use of a welding tool or gun.
