gas tungsten造句

• Plasma welding has since been developed into gas tungsten arc welding.
• Other uses include shielded metal arc welding and gas tungsten arc welding.
• Gas tungsten arc welding is most commonly used.
• The American Welding Society's official term is gas tungsten arc welding ( GTAW ).
• Manual gas tungsten arc welding is a relatively difficult welding method, due to the coordination required by the welder.
• Spark gap oscillators are still used to generate high frequency high voltage to initiate welding arcs in gas tungsten arc welding.
• Nonconsumable electrode processes, such as gas tungsten arc welding, can use either type of direct current, as well as alternating current.
• Thorium is used in gas tungsten arc welding ( GTAW ) to increase the high-temperature strength of tungsten electrodes and improve arc stability.
• "' Gas tungsten arc welding "'is an arc welding process that uses a nonconsumable tungsten electrode to produce the weld.
• Frame tubes are almost always joined by Gas Tungsten Arc Welding ( GTAW or TIG ) welding, although vacuum brazing has been used on early frames.
• Gas tungsten arc welding ( GTAW, also known as tungsten inert gas ( TIG ) welding ) equipment uses a permanent, non-melting electrode.
• Welding helmets are most commonly used with arc welding processes such as shielded metal arc welding, gas tungsten arc welding, and gas metal arc welding.
• La 2 O 3 tungsten electrodes are replacing thorianated tungsten electrodes in Gas tungsten arc welding ( TIG ) due to safety concerns with thorium's radioactivity.
• Gas tungsten arc welding, because it affords greater control over the weld area than other welding processes, can produce high-quality welds when performed by skilled operators.
• Argon is used in some types of arc welding such as gas metal arc welding and gas tungsten arc welding, as well as in the processing of titanium and other reactive elements.
• Constant current power supplies are most often used for manual welding processes such as gas tungsten arc welding and shielded metal arc welding, because they maintain a relatively constant current even as the voltage varies.
• Gas tungsten arc welding, after decades of development, was finally perfected in 1941 and gas metal arc welding followed in 1948, allowing for fast welding of non-ferrous materials but requiring expensive shielding gases.
• Gas tungsten arc welding, after decades of development, was finally perfected in 1941, and gas metal arc welding followed in 1948, allowing for fast welding of non-ferrous materials but requiring expensive shielding gases.
• Likewise, GMAW's use of a shielding gas does not lend itself to underwater welding, which is more commonly performed via shielded metal arc welding, flux cored arc welding, or gas tungsten arc welding.
• Coverage includes preparation for joints with the following : no backing rings; split or noncontinuous backing rings; solid or continuous backing rings; consumable insert rings; gas tungsten arc welding ( GTAW ) of the root pass ."
