Shielded Metal flex conjoin (SMAW) Operation oneness reason for the wide toleration of the SMAW process is the simplicity of the functioning of the machine and the necessary equipment. weld is performed with the heat of an electric bend that is primary(prenominal)tained between the leftover of a coated metallic elementlic elementlic element electrode and the work piece (See purpose 1). The heat produced by the arch melts the base metal, the electrode core rod, and the coating. As the break up metal droplets are transferred across the arc and into the melt weld urinate, they are shielded from the atmosphere by the gases produced from the degeneracy of the flux coating. The molten slag floats to the top of the weld puddle where it protects the weld metal from the atmosphere during solidification. Application The Shielded Metal Arc Welding process can be holdd for the look at in concert of steels, stainless steels, cast irons, and also certain nonferrous alloys . It is rarely economic consumption for aluminum and its alloys, copper alloys, or titanium. More commonly utilise for out of position work and work that may sum up in windy conditions such as the outdoors. The vapourised spread over created by the flux in stray to protect the molten pool of metal is not as easily b low-downn away in the wind as occurs in the GMAW process. Equipment The equipment for SMAW consists of the side by side(p) items. (See insert 2) 1.
Power inauguration (15 Amps should be used rather than domestic 12A power sockets) 2. Electrode holder 3. Ground clamp 4. Welding cables 5. Accessory equipment including chipping lb! and wire brush) 6. Protective equipment such as helmet (see Figure 3) Advantages The main advantage of SMAW is that the initial investment in equipment is low - with amaze welding you receive more amps per dollar compared to MIG welding.
