Shielded Metal flex conjoin (SMAW) Operation iodine reason for the wide toleration of the SMAW process is the simplicity of the carrying out of the machine and the necessary equipment. weld is performed with the heat of an electric bow that is master(prenominal)tained between the leftover of a coated alloy electrode and the work piece (See purpose 1). The heat produced by the fore melts the base alloy, the electrode core rod, and the coating. As the break up metal droplets argon transferred across the arc and into the liquid 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 engaged for the need unitedly of steels, stainless steels, cast irons, and also certain nonferrous alloys. It is rarely put on for alumi num and its alloys, copper alloys, or titanium. More commonly utilise for out of position work and work that may tag on up in windy conditions such as the outdoors. The volatilised spread over created by the flux in devote 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 reference book (15 Amps should be used rather than domestic 12A power sockets) 2. Electrode carrier 3. Ground clamp 4. Welding cables 5. Accessory equipment including chippi ng peter and wire brush) 6. Protective equi! pment such as helmet (see Figure 3) Advantages The main advantage of SMAW is that the initial investment in equipment is low - with stick by welding you receive more amps per dollar compared to MIG welding.
