    This is A practice weld using 304L stainless steel in .063" thickness.
    usually other alloys like 17-7ph, 15-7ph, are used for this test but the same techniques apply across the board

  • 3G Stainless TIG Welding Practice for AWS D17.1 Aerospace weld tests

    AWS D17.1 is the specification for aerospace fusion welding.

    It is common for 1G tests to be done in aerospace welding certification because shops often have positions and manipulators that can pretty much get every weld in the flat position.

    But sometimes employers require a 2G and or a 3G tes...

    A laser cut aluminum star provides lots of different angles and opportunity to learn things like hand position

  • How to TIG Weld Aluminum - Part 1

    There is a lot to talk about.
    things like tungsten electrodes..type and size ( i like 2% lanthanated for everything and 3/32 takes care of most of my daily welding)
    shielding gases ...argon is best to start but if you begin to specialize in thicker aluminum, it might make sense to use a blend of ...

  • TIG Welding Aluminum with Different Waveforms

    The current waveforms are advanced square wave, soft square wave, sine wave, and triangle wave.
    They all have slightly different looks, sounds and characteristics.
    Some waveforms are supposed to be better for thin metals, others for thicker metals.
    There is another advanced feature on a very few...
