Much of biochemistry deals with the structures, functions and interactions of biological macromolecules, such as proteins, nucleic acids, carbohydrates and lipids, which provide the structure of cells and perform many of the functions associated with life.
Gas metal arc welding (GMAW), sometimes referred to by its subtypes metal inert gas (MIG) welding or metal active gas (MAG) welding, is a welding process in which an electric arc forms between a consumable wire electrode and the workpiece metal(s), which heats the workpiece metal(s), causing them to melt, and join.as metal arc welding (GMAW), sometimes referred to by its subtypes metal inert gas (MIG) welding or metal active gas (MAG) welding, is a welding process in which an electric arc forms between a consumable wire electrode and the workpiece metal(s), which heats the workpiece metal(s), causing them to melt, and join.
-Submerged Arc Welding (SAW); solid wire is being used for SAW welding process. -Gas Metal Arc Welding (GMAW) or MIG welding; either solid wire or metal cored wire is being used for MIG welding process. -Gas Tungsten Arc Welding (GTAW) or TIG welding; rod or solid wire is being used for TIG welding process.
