So after reading the instructions (I totally did NOT jump the gun and try to go at it without reading the instructions first...) I managed to get all of my settings dialed in. I used a solid .035" aluminum welding wire with 100% Argon flowing at 25cfm and was fortunate enough to have a 220V outlet to supply sufficient power. We had a piece of scrap aluminum laying around the shop that I had the opportunity to practice on and dial in these settings along with the help of my Miller app on my phone.
My bead on the scrap metal was looking pretty good and decided to go for the hand rail. Of course, It started to fail miserably as I did not take into account that the hand rail was thicker than the scrap aluminum I had been welding. So, after readjusting to the settings I listed above, I managed to save my weld. Upon completion, I took a step back and felt an overwhelming sense of pride and accomplishment in my first aluminum weld. Take a look!
The weld on the far right is my co-worker, the middle and one directly to the right are mine.
The ramp. The bottom of the last post down is where I welded.
Not to shabby for first time!
Hours for last week: 31.25
Running total: 115.25
Nice job on figuring out aluminum. One alwasys needs to have a few CLEAN STAINLESS STEEL wire brushes available that are ONLY used for aluminum to clean the weld area before a bead is placed. Clean, clean, clean is the rule for aluminum.
ReplyDeleteNice work.
I see that you are a bit behind on your blog entries though...
Aluminum is a lightweight, soft, low strength metal which can easily be cast, forged, machined, formed and welded. Unless alloyed with specific elements, it is suitable only in low temperature applications. Aluminum is readily joined by welding, brazing, and soldering. Aluminum welding st louis
