Hey guys, I need yalls help with these welds. The setup I'm using is a #12 fupa, 3/32 electrode, 5/8 stickout, and 20-25cfh. They keep coming out grey and not very colorfull. I used anywhere from 130 to 150amps and the heat affected areas is large even with fast travel speed. Also this is 1/8 thick.

I had to certify for 1” here’s my root and hot pass feel free to rate it but only if you post yours next 😜🤣

Thank you for requesting this post hope it answers your question So the question was “Are aluminum TIG welds supposed to be hazy or shiny?” The answer is tricky but as a whole Shiny is the goal for TIG aluminum welds , as a dull or hazy finish often tells us that there is some form of oxidation or contamination. Getting a shiny bead requires balancing heat input, proper gas coverage, clean base metal, and correct machine settings balancing the heat is done by using the foot pedal to lower and raise your amperage as needed aluminum gets real hot real fast so foot pedals are pretty much necessary with aluminum proper gas coverage isn’t just about flow rate and cup size it’s about your angle just as much but a size 8 cup is what I prefer for most aluminum jobs but that’s preference mostly remember as well that too much gas flow can cause the Venturi effect I’ll talk more about that later clean clean clean clean the metal first remembering that aluminum isn’t like steel check the aluminum lesson for more info if you don’t already know what I mean (tip to think about “your filler rod is also aluminum…keep it within the gas shield and clean it too!!” And as far as correct machine settings your amperage is dependent on your travel speed which depends on your style But the ac balance is dependent on your base metal and whether or not you want more cleaning action (+) or more penetration (-) more cleaning will cause your tungsten to ball up more and quicker and also you will see more frost around the toe of your welds here’s a few tips hope this helps - Clean the base metal: Thoroughly clean the aluminum with a stainless steel wire brush designated only for aluminum before welding. Any residue or oxide layer from improper cleaning will cause a dull finish - Optimize AC balance and frequency: Adjust your AC balance setting toward the electrode positive side to increase the cleaning action. Too much electrode negative can cause contamination and a dull finish. - Use proper gas coverage: Ensure you have sufficient shielding gas flow and use a gas lens with a larger cup. This helps prevent oxygen from reaching the molten puddle, which is a primary cause of haziness. - Control heat input: A dull finish can be a sign of overheating, causing you to weld too slowly. Use sufficient amperage to create a puddle quickly, and then use your foot pedal to control the heat. A smaller heat-affected zone is more likely to have a shiny finish. - Consider the filler material and tungsten:Some filler alloys can lead to a slightly less shiny finish. Use the correct tungsten for AC welding, and consider the benefits of using 2% lanthanated tungsten. - Maintain a consistent arc: Keep a tight and consistent arc to prevent the arc from wandering. An excessive arc length can lead to a loss of gas quality and therefore contamination.
