Gas tungsten arc welding (GTAW, also known as tungsten inert gas welding or TIG, and heliarc welding when helium is used) is an arc welding process that uses a non-consumable tungsten electrode to produce the weld. The weld area and electrode are protected from oxidation or other atmospheric contamination by an inert shielding gas (argon or ...
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. [1] [2 ...
The old fashioned glass, otherwise known as the rocks glass, whiskey glass, and lowball glass [1] [2] (or simply lowball), is a short tumbler used for serving spirits, such as whisky, neat or with ice cubes ("on the rocks"). It is also normally used to serve certain cocktails, such as the old fashioned.
An oversized tumbler for serving chilled beverages, while reducing the need to frequently refill the glass. A tumbler is a flat-floored beverage container usually made of plastic, glass or stainless steel. Theories vary as to the etymology of the word tumbler. One such theory is that the glass originally had a pointed or convex base and could ...
A plasma ball with filaments extending between the inner and outer spheres. A plasma ball, plasma globe, or plasma lamp is a clear glass container filled with noble gases, usually a mixture of neon, krypton, and xenon, that has a high-voltage electrode in the center of the container.
Glass, 200ml (7 fl. oz.) Australian beer glass (Queensland and Victoria) Handle, 425ml New Zealand beer glass; Jug, 750–1000ml served at pubs in New Zealand; Middy, 285ml (10 fl. oz.) Australian beer glass (New South Wales) Pilsner glass, for pale lager; Pint glass, for an imperial pint of beer or cider
Stained glass shards used for mosaic glass are also tumbled. No abrasive is used, to avoid clouding the glass; there is only water as a lubricant. The object of this tumbling is to remove the sharp edges from the glass, so that it may be handled safely. As little as 8 hours of tumbling may be sufficient for tumbled glass.
The tip of the electrode needs to be at a lower angle to the workpiece, which allows the weld pool to flow out of the arc. As the electrode melts, the flux covering disintegrates, giving off shielding gases that protect the weld area from oxygen and other atmospheric gases. In addition, the flux provides molten slag which covers the filler as ...
