2 industries that decision for tig welding certification are:

1. Industrial piping, (which embrace boiler tubes)
2. Aerospace and aviation (manufacture and overhaul/mend)

For tig welding certification in piping, stress vessels, and boilers, ASME portion IX of the “Boiler and Stress Vessel Code” specifies the necessities for passable welding exams.

For Aerospace tig welding, the American Welding Society (AWS) D17.1 – “Specification for Fusion welding for Aerospace Purposes” is the code for welding certification exams.

Much more regularly than not, a 6G posture welding verify is required to certify for Pipe welding work alternatives. On quite a few boiler careers, 2″ hefty wall tubing is tig welded all the way in which out within the 6G place making the welder presumably swap palms, or on the very least get in some uncomfortable positions. That’s the reason 6G placement Tig welding exams are thought to be probably the most powerful.

More often than not, sheet steel take a look at gadgets within the .020″-.125″ thickness assortment are utilized for aerospace welder qualification testing. The 6G welding examination is just utilized typically given that it doesn’t correctly symbolize the scope of welding jobs executed for many aerospace and aviation welding functions. AWS D17.1 even has a provision for welders to certify on a scrap side or mock up of a weld that’s not represented properly by a primary groove or fillet weld.

ASME part IX Boiler and Stress Vessel Code has been round for a extraordinarily prolonged time, however AWS D17.1 is pretty new and was ready to substitute 2 outdated Mil requirements… 1595a and 2219.

1 level equally welding certification necessities have in in style is that the verify welds which can be chosen to be utilized for certification checks solely qualify the welder for a assortment of positions, thicknesses, and joint types. No single verify qualifies for all of the potential supplies, thickness, positions, and joint varieties which can be possible. That’s the reason some welders hold a dozen or much more certifications.

Only one main variation in welding assessments for these 2 industries is that the preliminary welding examination for Pipe welding employment are primarily completed utilizing very low carbon metal or chrome steel. Different merchandise like inconel are sometimes utilized additionally however not nearly as considerably as carbon steel and stainless.

Within the Aerospace and aviation industries, It isn’t remarkable for a welder to be analyzed on carbon or minimal alloy steels, stainless steels, nickel alloys, aluminum, magnesium, titanium, cobalt alloys, and even some refractory alloys like Niobium…with unbiased welding checks wanted for every particular person product classification.

1 of the foremost dissimilarities in Tig welding pipe and tig welding airplane or aerospace areas is within the thickness of substance. In Airplane welding , most nearly every thing is thinner. and that signifies lesser electrodes, smaller sized filler wire, lesser torches…and in Plane and Aviation tig welding, a 1/16″ rod is taken into account fairly main.
