Welding Certification Tests For Aviation and Aerospace Repair Stations

American Welding Society D17.1 "Specification for Fusion Welding for Aerospace Applications" is the market requirement for ending up being a licensed welder for fixing or producing aircraft parts.

In the past, MIL std 5021 was the conventional and cluster welds of tubing entwined to plate where the conventional test offered to license welders.

MIL std 1595a came along and resolved various metal types and more recent procedures like electron beam and laser. Mil standard 1595a was later on relabelled AMS 1595a without any modifications in the file aside from name.

AWS D17.1 is the most recent and biggest requirements for accrediting welders and serves not just as a requirement for licensing welders, however likewise a requirements for all welding procedures made use of in the aviation and aerospace markets.

Welding Certification Tests For Aviation

Generally right here is how the welding certification part works:


  • Metals are classified into 8 groups or classifications.
  • metal groups 1,2, and 3 are additional separated into a and b classifications with the b classification thought about the most challenging to weld.
  • Groove welds and fillet welds are utilized to accredit welders. Generally a test joint in the.032" -.050" density range is utilized for the welding certification tests however AWS D17.1 has arrangements for all densities of metals.
  • Typically 2 inch by 5 inch plates are made use of for the groove weld tests in this density.
  • Groove welds are frequently x rayed, however bend screening is often made use of.
  • Fillet welds (tee joints) are needed in order for the welder to be certified to weld a fillet weld listed below.063".
  • Groove welds get fillet welds too for everything over.063".

Suggestion for passing an aerospace welding certification test:.


  • Make sure your vision is great. (AWS D17.1 even needs a vision test).
  • Use additional magnification for the thin things. Even with excellent vision, seeing a puddle on inconel 718 that is.032" thick can be tough. You cant weld it if you cant see it.
  • Keep your tungsten electrodes clean and sharp.
  • Keep as close an arc and you attempt without dipping your wick.
  • If you dip your wick, stop and alter electrodes.
  • Clean the metal and submit the sheared edge of any groove weld, specifically titanium, aluminum, and magnesium.
  • If one is supplied, - Follow the WPS. In some cases the test inspector tries to find your capability to follow technical directions in addition to your capability to pass a welding test.
