American Welding Society AWS D17.1 is the specification for Aerospace Fusion Welding Applications. This Specification provides details for welding certification as well as production welding.
A typical test required to certify a welder in aluminum is the 2f tee fillet weld test.
TIG Welding Thick Aluminum Machine Shop type repair
A common weld repair is to weld up a part that was accidentally machined wrong ..or a tool crashed or a corner got smashed when someone dropped a part.
In this video, I had a piece of thick aluminum that was a proto type part but it had an area that was also mis machined. preheat and bead sequenc...
TIG Welding Aluminum Practice "The Aluminum Drill"
This video shows lots of beads during an exercise I call "the aluminum drill".
In sports, there are drills designed to improve certain skills.
Because Aluminum requires so much more feeding of the wire than steel, this drill will help that filler wire feeding hand to get up to speed.
TIG Welding Aluminum Techniques for Butt and Tee Joints
The basic settings are 100-140 amps using foot pedal so basically what that mean is at times I am at 140 amps but also much lower when heat soaks the small practice piece.
i used nearly 140 amps but when the aluminum gets soaked with heat, I used the foot pedal to use less amperage.
AC balance ...
TIG Welding Settings and Techniques for 16ga Aluminum
16ga 6061 aluminum using 1/16" (1.6mm) 4043 filler.
I used a tapered 2% lanthanated 3/32" (2.4mm) tungsten.
Welding small aluminum coupons with a chill backing,
This can also be done without backing but on small pieces of aluminum heat can saturate the piece and the puddle gets very watery.
Tips for Passing Your Aluminum TIG Welding Test D17.1 spec
You’ve probably read how aluminum needs to be really cleaned thoroughly before welding.
A lot of aluminum can be tig welded without doing a whole lot of cleaning it really depends on the application.
For general fabrication, often times a wipe with acetone or alcohol will do the trick if the me...
This project was sent to me by a laser cutting company that sells them as weldable kits. It was a good practice project that required a lot of different torch angles. Rotating the torch head as you weld is shown along with plenty of instructive arc shots
