The risk of VAP is highest early in thecourse of hospital stay, and is estimated to be 3%/day duringthe ï¬rst 5 days of ventilation, 2%/day during Days 5 to 10 ofventilation, and 1%/day after this (17).
there is a difference. There are other here who could elaborate further but MIG stands for metal inert gas. This is Argon or c02. Inert meaning the gas has no affect on the weld except to shield it from oxidation, from the atmosphere. MAG is metal active gas.
MIG can be used automatically or semiautomatically. An example of automatic MIG is a robotic arm welding car frames at an auto assembly plant. Semiautomatic is when an operator holds the MIG gun and manipulates the weld pool. In automatic MIG, an operator sets up and watches the machine. An experienced welder is the preferred operator, because he has the right touchand knows what it means to be in the welding zone. (In the zone is when you become one with the process of the weld metal becoming one with the base metal, grasshopper.
