  2. Fillet weld - Wikipedia

    en.wikipedia.org/wiki/Fillet_weld

    Making a fillet weld with gas metal arc welding. Fillet welding refers to the process of joining two pieces of metal together when they are perpendicular or at an angle. . These welds are commonly referred to as tee joints, which are two pieces of metal perpendicular to each other, or lap joints, which are two pieces of metal that overlap and are welded at the

    Plasma Arc Welding: 15: PAW Nonconsumable electrode, constricted arc Tubing, instrumentation Shielded Metal Arc Welding [5] 111: SMAW Consumable electrode covered in flux, can weld any metal as long as they have the right electrode Construction, outdoors, maintenance Submerged Arc Welding: 121: SAW Automatic, arc submerged in granular flux

  4. Gas tungsten arc welding - Wikipedia

    en.wikipedia.org/wiki/Gas_tungsten_arc_welding

    GTAW weld area. Manual gas tungsten arc welding is a relatively difficult welding method, due to the coordination required by the welder. Similar to torch welding, GTAW normally requires two hands, since most applications require that the welder manually feed a filler metal into the weld area with one hand while manipulating the welding torch in the other.

  5. Spot welding - Wikipedia

    en.wikipedia.org/wiki/Spot_welding

    Spot welding can keep the battery from getting too hot, as might happen if conventional soldering were done. Good design practice must always allow for adequate accessibility. Connecting surfaces should be free of contaminants such as scale, oil, and dirt, to ensure quality welds. Metal thickness is generally not a factor in determining good welds.

  6. Arc welding - Wikipedia

    en.wikipedia.org/wiki/Arc_welding

    Arc welding power supplies can deliver either direct (DC) or alternating (AC) current to the work, while consumable or non-consumable electrodes are used. The welding area is usually protected by some type of shielding gas (e.g. an inert gas), vapor, or slag. Arc welding processes may be manual, semi-automatic, or fully automated.

  7. Welding joint - Wikipedia

    en.wikipedia.org/wiki/Welding_joint

    The closed square butt weld is a type of square-groove joint with no spacing in between the pieces. This joint type is common with gas and arc welding. For thicker joints, the edge of each member of the joint must be prepared to a particular geometry to provide accessibility for welding and to ensure the desired weld soundness and strength.

  9. Electric resistance welding - Wikipedia

    en.wikipedia.org/wiki/Electric_resistance_welding

    Spot welding is a resistance welding method used to join two or more overlapping metal sheets, studs, projections, electrical wiring hangers, some heat exchanger fins, and some tubing. Usually power sources and welding equipment are sized to the specific thickness and material being welded together.
