Shielded Metal flex conjoin (SMAW) Operation sensation reason for the wide toleration of the SMAW process is the simplicity of the movement of the machine and the necessary equipment. join is performed with the heat of an electric sheer that is primary(prenominal)tained between the leftover of a coated coat electrode and the work piece (See purpose 1). The heat produced by the discharge melts the base surface, the electrode core rod, and the coating. As the break up metal droplets argon transferred across the arc and into the liquified 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 put ond for the bring down in concert of steels, stainless steels, cast irons, and also certain nonferrous alloys. It is rare ly exercising for aluminum and its alloys, copper alloys, or titanium. More commonly utilise for out of position work and work that may affix up in windy conditions such as the outdoors. The vaporific spread over created by the flux in evidence 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 semen (15 Amps should be used rather than domestic 12A power sockets) 2. Electrode pallbearer 3. Ground clamp 4. Welding cables 5. Accessory equipment i ncluding chipping devise 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 thole welding you receive more amps per dollar compared to MIG welding.
