  3. Gas tungsten arc welding - Wikipedia

    en.wikipedia.org/wiki/Gas_tungsten_arc_welding

    TIG welding is most commonly used to weld thin sections of stainless steel and non-ferrous metals such as aluminium, magnesium, and copper alloys. A related process, plasma arc welding, uses a slightly different welding torch to create a more focused welding arc and as a result is often automated. [1]

  4. 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 ...

    There are 3 major CSA Standards to which welders may be qualified: CSA W47.1 [4] for steels (including stainless steels), CSA W47.2 [5] for aluminum, and CSA W186 [6] for reinforcing bars. Under these CSA standards, welder qualification testing is carried out every 2 years by the Canadian Welding Bureau to ensure ongoing competence.

  8. SAE steel grades - Wikipedia

    en.wikipedia.org/wiki/SAE_steel_grades

    Type 304—the most common grade; the classic 18/8 (18% chromium, 8% nickel) stainless steel. Outside of the US it is commonly known as "A2 stainless steel", in accordance with ISO 3506 (not to be confused with A2 tool steel). [6] The Japanese equivalent grade of this material is SUS304.

  9. Stainless steel - Wikipedia

    en.wikipedia.org/wiki/Stainless_steel

    The average carbon footprint of stainless steel (all grades, all countries) is estimated to be 2.90 kg of CO 2 per kg of stainless steel produced, [97] of which 1.92 kg are emissions from raw materials (Cr, Ni, Mo); 0.54 kg from electricity and steam, and 0.44 kg are direct emissions (i.e., by the stainless steel plant). Note that stainless ...
