PPT Chapter 31 Gas Flame and Arc Processes PowerPoint Presentation

Please see the above schematic diagram (Figure - 2) of SMAW for a better understanding. The welding machine is connected to the power supply. Stick welding electrodes can be connected to negative or positive terminals as per the electrode characteristics.. Download scientific diagram | Schematic of shielded metal arc welding process from publication: Underwater Welding-Present Status and Future Scope | Welding in offshore and marine application is.

Facts About SMAW SMAW is considered as one of the least efficient welding process because the operator's factor of chipping away slag and changing of worn-out electrodes during the process. Actual welding technique utilized depends n the electrode, composition of the work piece, and the position of the joint to be welded.. The SMAW welding machine produces a constant amperage in alternating current (AC) or direct current (DC).. This current travels from the machine, through the electrode, across the welding arc, and back to the machine through the work clamp. When the electrode touches the workpiece in a scratching motion, the current will jump the gap between the electrode tip and the base metals.
