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.
The major difference between Mig and Tig welding is that one process uses a continuously feeding wire (MIG) and the other you use long welding rods and slowly feed them into the weld puddle (TIG). MIG and TIG welding both use an electric arc to make the weld.
