When to use nitrogen purge in arc welding?
AWS C5.5/C5.5M:2003, Recommended Practices for Gas Tungsten Arc Welding, states that nitrogen is widely used in Europe as a purge gas, and that it is used for austenitic stainless steel, copper, nickel alloys, carbon and low alloy steels, but it should not be used with reactive metals.See all results for this questionWhat's the proper arc length for welding alloy?The proper arc length when welding alloy metals is as tight as possibleon the verge of touching the metal. A tight arc produces a well-defined puddle and better directional control, which is necessary when dealing with a sluggish weld puddle.See all results for this questionWhat's the difference between arc welding and TIG welding?An arc welding process, TIG welding stainless steel involves the use of an non-consumable tungsten electrode in order to deliver a weld.See all results for this question

General Welding Guidelines - MCAA
Welding without the addition of filler metal, such as might be used for tight-butt welds on schedule 10 pipe or for wash passes made on the cover to improve surface appearance, is not permitted unless the WPS specifically permits welding without the use of filler metal (i.e. the column ROOT on the WPS has NONE for the filler metal.)Gas Tungsten Arc Welding - an overview | ScienceDirect TopicsPeter Smith, in The Fundamentals of Piping Design, 2007. Gas Tungsten Arc Welding. Gas tungsten arc welding, also known as tungsten inert gas (TIG) welding, is an arc welding process that uses a nonconsumable tungsten electrode to produce the weld. The filler metal is added from an external source, usually as bare metal filler rod. The weld pool area is protected from the atmosphere and schedule 10 steel pipe Argon arc weldingGas Metal Arc Welding - Lincoln ElectricGas Metal Arc Welding (GMAW), by definition, is an arc welding process which produces the coalescence of metals by heating them with an arc between a con-tinuously fed filler metal electrode and the work.
