Visit my store at weldmongerstore.com/collections/weldmonger-tig-accessory-kits for TIG cup Kits, TIG Fingers, Gloves, Tungsten, Filler metal, and other quality welding tools. New products being added weekly.
The welding specification for aerospace welding is AWS D17.1
D17.1 replaced mil std 1595a and when that happened the tolerance for lack of fusion in fillet weld test joints on .063" and thinner was made much tighter.
That makes a tee joint fillet weld test a matter of puddle control to achieve fusion into the root, but not melt thru the back side at all on .063" and thinner.
.063" is relatively easy not to melt thru but when you get down to .040" and thinner, things get more difficult.
In this video, I used .063" 304L stainless for a practice joint.
An aerospace weld test would most likely use 17-7ph or 15-7ph for qualifying a welder for group 2 iron based stainless alloys.
But 304L is easier to find and way cheaper and still makes for good practice.
