SHIELDED METAL ARC WELDING
Shielded metal arc welding (SMAW), also known as manual metal arc welding (MMA or MMAW), flux shielded arc welding or informally as stick welding, is a manual arc welding process that uses a consumable electrode covered with a flux to lay the weld. SMAW is often used to weld carbon steel, low and high alloy steel, stainless steel, cast iron, and ductile iron.
GAS TUNGSTEN ARC WELDING MACHINE
Gas tungsten arc welding (GTAW) is an arc welding process that uses a non-consumable tungsten electrode to produce the weld. GTAW is most commonly used to weld thin sections of stainless steel and non-ferrous metals such as aluminum, magnesium, and copper alloys.
A cutting tool or cutter is any tool that is used to remove material from the workpiece by means of shear deformation. Cutting may be accomplished by single-point or multipoint tools. Single-point tools are used in turning, shaping, planing and similar operations, and remove material by means of one cutting edge.
