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.
Why is it called MIG/MAG welding and what does this mean? MIG welding stands for Metal Inert Gas welding (inert). An inert gas (rare gas) is e.g. Argon or Argon + Helium. Its task is to protect the welding deposit, the melting wire electrode and the arc against the oxidising effects of oxygen in the air. Application: in nonferrous metals.
