I usually use 4043 filler wire for welding 6061-T6 and castings. My friend told me I should switch to 4047 because it’s stronger. Is that true? It’s more expensive than 4043. Is it worth it? 2016-12-21 10:20:08

I know that when aluminum alloys are gas tungsten arc-welded (GTAW), usually we use alternating current (AC) because it give some sort of cleaning action. Can you explain what it is and how it works? 2016-12-21 10:11:56

I have a project I want to build from aluminum sheet and extrusions. Some of my friends tell me to make it entirely from 6061-T6. Other tell me to use other alloys, mostly 5000 series. The project entails a lot of welding. Which alloy should I use? 2016-12-21 10:11:07
