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.
This type of welding uses an electrical power source to create an arc between the base metal and an electrode stick or wire. The arc is struck by turning on the welding machine, adjusting the settings, getting safety gear and materials in place and then scratching or tapping the electrode against the base metal.IG welding is one of the more difficult welding processes to learn and is most often used to weld very thin pieces of stainless steel and non-ferrous metals such as magnesium and aluminum. Filler metal is added to the weld from a tungsten rod that is separate from the electrode.
