Shielded Metal flex conjoin (SMAW) Operation ace reason for the wide toleration of the SMAW process is the simplicity of the surgical operation of the machine and the necessary equipment. weld is performed with the heat of an electric veer that is brinytained between the leftover of a coated alloy electrode and the work piece (See purpose 1). The heat produced by the wind melts the base alloylic element, the electrode core rod, and the coating. As the break up metal droplets atomic number 18 transferred across the arc and into the molten 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 enforced for the embark on together of steels, stainless steels, cast irons, and also certain nonferrous alloys. It is rarel y make use of for aluminum and its alloys, copper alloys, or titanium. More commonly utilise for out of position work and work that may annex up in windy conditions such as the outdoors. The volatilised spread over created by the flux in separate 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 outset (15 Amps should be used rather than domestic 12A power sockets) 2. Electrode carrier 3. Ground clamp 4. Welding cables 5. Accessory equipment including chipping putz 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 acquire welding you receive more amps per dollar compared to MIG welding.
