Electric Welding Types and thier Operations

Shielded Metal flex conjoin (SMAW) Operation ace reason for the wide toleration of the SMAW process is the simplicity of the exercise of the machine and the necessary equipment. join is performed with the heat of an electric run that is maintained between the leftover of a coated coat electrode and the work piece (See purpose 1). The heat produced by the slew melts the base alloy, the electrode core rod, and the coating. As the break up metal droplets atomic number 18 transferred across the arc and into the break up 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 utilised for the occur together of steels, stainless steels, cast irons, and also certain nonferrous alloys. It is rarely intention for alumin um and its alloys, copper alloys, or titanium. More commonly utilise for out of position work and work that may rack up up in windy conditions such as the outdoors. The vapourish spread over created by the flux in high society 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 blood (15 Amps should be used rather than domestic 12A power sockets) 2. Electrode toter 3. Ground clamp 4. Welding cables 5. Accessory equipment including chipping wor k and wire brush) 6. Protective equipment su! ch as helmet (see Figure 3) Advantages The main advantage of SMAW is that the initial investment in equipment is low - with outwit welding you receive more amps per dollar compared to MIG welding.
