Peter and Matt, thank you for posting this information, it is absolutely invaluable to someone trying to teach himself to weld aluminium,
Cheers Charlie

Regarding welding lenses for Ali, I used to use Honeywell clearways visor number CV85/5W/EU, these are about £20 (from memory) in the UK (lens only) They were recommended on one of the forums and do indeed cut out the flux glare when welding Ali. They give a good clear view, BUT one week when doing a lot of Ali welding I was getting zigzag patterns around my peripheral vision (similar to a migraine I believe) I therefore bit the bullet and bought Kent's headgear and lenses. They are fantastic and give great clarity to the weld pool. I have not had vision problems due to welding since (though caffeine can give me the same zigzag patterns).
Kent's stuff is very reasonably priced, but to get it to the UK is expensive with shipping and customs charges. However you get what you pay for in life. Hope this helps. Cheers Dave

I found some UK eye wear for OA Ali welding a little while ago that work well by taking out the orange flare and protect - see the following link http://allmetalshaping.com/showthread.php?t=9151 Jim Ps the vibroshear is getting some use 👍

Hi Matt, thanks for your explanation and tips. One thing that I don't understand is the oscilating of the weld. Is this done after welding? Cheers Richard.

Sounds like you get myopic migraines. I'm get them from time to time and have to lie down with my eyes closed until it passes. Sometimes they bring a bad headache. Not pleasant |

Gas welding aluminium
Hi all I am old school and I never use aluminium rods I only use thin strips of the aluminium that I am welding,I agree it is best to flux edges and I use small circular motion on torch,the filler rod is only there for tacks,and if I need to remove excess heat from weld area. I never grind welds only a body file after planishing.
As for goggles my old goggles where about thirty five years old and I was having trouble finding a suitable replacement,I did not want visor although I now wear glasses for close up work, so I purchased a visor and cut It down to fit my flip up goggles this means I now have enough visor left to change the lens two or three more times.

An old german aircraft guy told me to keep the flame stady, not rotate it. I will try the rotation method next time. And he told me to weld right after the tacks, no cleaning and refluxing. Again...works for me. I use blue welding lenses and I use the welding rod all the time because I want a nice raised bead that I usually file down a little, then lightly hammer it before planishing it. The hammering is said to improve weld density...that is what an old german aircraft book from the 40s says.
