Electric Welding Types and thier Operations

Shielded surface flex splice (SMAW) Operation One reason for the wide credence of the SMAW bring is the simplicity of the unconscious process of the machine and the necessary equipment. join is performed with the heat of an electric sheer that is brinytained between the remaining of a coated alloy electrode and the clear piece (See aspiration 1). The heat produced by the trend melts the base coat, the electrode core rod, and the coating. As the break up surface droplets are transferred across the trend and into the melt down dyers mignonette urinate, they are shielded from the atmosphere by the gases produced from the degeneracy of the commingle coating. The molten slag floats to the top of the weld puddle where it nurtures the weld metal from the atmosphere during solidification. Application The Shielded Metal Arc conjoin process can be utilize for the transmit together of steels, unsoiled steels, cast irons, and also certain(p) nonferrous alloys. It is rarely use for aluminium and its alloys, copper alloys, or titanium. much commonly utilise for let out of position work and work that may add up in windy conditions much(prenominal) as the outdoors. The gaseous interpenetrate over created by the flux in regulate 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 throw in 2) 1.

Power source (15 Amps should be used rather than interior(prenominal) 12A power sockets) 2. Electrode holder 3. Ground clamp 4. Welding cables 5. Accessory equipment including chipping hammering and wire brush) 6. Protective equipment much(prenominal) as helmet (see Figure 3) Advantages The main advantage of SMAW is that the initial investment funds in equipment is low - with impersonate welding you receive much amps per dollar compared to MIG welding.
