Teachers, parents, and administrators might want to know how well students are reading and writing in general, independent of the specific instructional program. This requires a different type of formal assessment.
GMAW or Gas Metal Arc Welding. More commonly called MIG welding this welding type is the most widely used and perhaps the most easily mastered type of welding for industry and home use. The GMAW process is suitable for fusing mild steel, stainless-steel as well as aluminium. GTAW or Tungsten Inert Gas.
As the weld is laid, the flux coating of the electrode disintegrates, providing a shielding gas and a layer of slag, both of which protect the weld from contamination until it cools. | Because of the versatility of the process and the simplicity of its equipment and operation, shielded metal arc welding is the most commonly used welding process. SMAW also is known as manual metal arc welding (MMA or MMAW), flux shielded arc welding, and stick welding,
