companies that require tig welding certification usually are-
Industrial piping which includes boiler tubes Aerospace along with aviation manufacture and overhaulrepair For tig welding certification inside piping pressure ships and boilers ASME part IX of the Boiler and Tension Vessel Code specifies the factors for acceptable welding assessments.
For Aerospace tig welding the Us Welding Society AWS D17.1 – Specification for Fusion welding with regard to Aerospace Applications is the code intended for welding certification tests.
Generally a 6G position welding test is required to certify intended for Pipe welding jobs. In many boiler jobs 2 heavy wall hoses is tig welded all the way outside in the 6G position doing the welder either switch hands or at least get involved some uncomfortable opportunities. That is why 6G position Tig welding tests are considered the most difficult.
Most likely sheet metal check pieces in the 0.020-0.125 thickness range are used for aerospace welder qualification testing. The actual 6G welding test is only utilised occasionally because it wont accurately represent this scope of welding projects performed for most aerospace and aviation welding applications. Online job qualification AWS D17.1 even has a provision for welders to certify on a scrap element or mock of a weld that is not represented well by a ordinary groove or fillet weld.
ASME section IX Boiler and Tension Vessel Code has been online for a very long time but AWS D17.1 is relatively completely new and was published to replace 2 aged Mil standards… 1595a in addition to 2219.
One thing both welding accreditation specifications have in common would be that the test welds that are picked out to be used for certification tests only are eligible the welder for a range of positions thicknesses and joint types. No single test qualifies for all the possible material thickness jobs and joint kinds that are possible. Thats why some welders hold 12 or more certifications.
One main difference with welding tests for these 2 industries is that the preliminary welding test for Water pipe welding jobs are largely done using low carbon steel or steel. Other materials like inconel are sometimes used also and not nearly as much as carbon steel and stainless.
In the Aerospace and aircraft industries It is not uncommon for a welder to be tested on carbon or even low alloy steels steel steels nickel alloys lightweight aluminum magnesium titanium cobalt alloys and in many cases some refractory alloys including Niobium…with separate welding exams required for each product category.
One of the main variations in Tig welding pipe and tig welding airplane or aerospace parts consistantly improves thickness of material. Throughout Aircraft welding most all things are thinner. and that means smaller electrodes smaller gel wire smaller torches…plus in Aircraft and Aviation tig welding a 116 rod is considered pretty big.
