  2. 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.

  3. Arc welding - Wikipedia

    en.wikipedia.org/wiki/Arc_welding

    Gas tungsten arc welding (GTAW), or tungsten/inert-gas (TIG) welding, is a manual welding process that uses a non-consumable electrode made of tungsten, an inert or semi-inert gas mixture, and a separate filler material. Especially useful for welding thin materials, this method is characterized by a stable arc and high quality welds, but it ...

  4. List of welding processes - Wikipedia

    en.wikipedia.org/wiki/List_of_welding_processes

    This is a list of welding processes, separated into their respective categories. The associated N reference numbers (second column) are specified in ISO 4063 (in the European Union published as EN ISO 4063 ). [ 1 ]

  5. TIP TIG - Wikipedia

    en.wikipedia.org/wiki/TIP_TIG

    TIP TIG welding torch. TIP TIG is a subset of gas tungsten arc welding (GTAW), using a mechanism called filler wire agitation to enhance molten weld pool dynamics. This agitation has been found to enhance the weld puddle fluidity and release evolving gases, reducing the chances of inclusions and porosity, and also separate impurities.

  6. Orbital welding - Wikipedia

    en.wikipedia.org/wiki/Orbital_welding

    Due to the precision of orbital TIG welding, even the smallest standard tube diameters from 1.6 millimetres can be processed. On a larger scale, pipes with diameters up to 170mm and walls up to 3.5mm thick can be joined using closed chamber weld heads.

    The search for missing hiker Susan Lane-Fournier, 61, took a tragic turn after her body was found over the weekend in Welches, Oregon, an unincorporated community at the base of Mount Hood.

  9. Weld purging - Wikipedia

    en.wikipedia.org/wiki/Weld_purging

    Most weld purging is carried out on joints made by the TIG or GTAW arc welding process. [6] When the laser welding process is chosen, joints or welds being made on reactive materials will need to be carried out and in the case of electron beam welding, this is carried out in a vacuum, in which case purging takes place by complete evacuation of all gas.
