Now to my question.............. There was good weld penetration on the butt weld.
Stu..
Aircraft are welded aluminum skins using butt welds all the time..using a heli-arc (Helium) arc welder with a foot pedal power control.(Better stability) Quote:
I started welding that way back in the early '60's, on scrap aluminum in the metal shop in the RCAF on the hanger line when I had a few hours off I would go play with the aircraft welding machines.. You could butt weld two pieces of aircraft aluminum skin butt welded and it looked like one piece.. Strong like Bull..

Stuart,
Neat job! Try a polyurethane (PU) sealant from an automotive paint shop. HTH Hanno

TIG welding is not MIG welding..and is used for Aluminum..stainless steel ..mild steel..and even titanium.. I'll start again.. Quote:
Good luck. Go to a good machine shop and ask to see some one TIG welding..you will be impressed WE used to play around welding mild steel shim stock..butt welds..takes some practice but really nice when you get on it. Good luck http://www.youtube.com/watch?v=4TIQY...feature=fvwrel

As a welder and fabricator by trade I would stand by the use of MIG for what Stuart has done. It is ideal for the enthusiast as Stuart has proven.
Alex, your barking up the wrong tree. MIG enables smaller welds and less heat in the joints, multiple tack welds is essentially what you do or if you drill one piece and lay it on top the other piece and do a weld through the hole and seal it you are mimicing a spot weld in effect, although a spot weld is done by a pair of copper tongs clamping the two materials and passing a current through them and the work pieces. TIG welding is far hotter and not worth the enthusiast playing with on jobs like this. It puts a ton of distortion into the panels. Heliarc is a term from the stone ages and those in the trade call it TIG nowadays. R |

Very impressive body work....
Stuart
Look up Eastwood supplier for possible coating..... .....or visit a professional body paint shop or a supplier...... ask them how they would do it ......... if you make your enquiry short and sweet some of them are very helpful. Some of the polyurethane coatings will stick to anythng and act as a binder coat for the cover up OD you would use........ I like your approach to do it right....even if it may not be readily visible when standing next to it. Bob

Aluminum works well for the filling of holes as a backing plate...is lighter and waaaay cheaper than brass or copper but does heat up quickly so a pail of water handy helps. I have done similar to the holes the Army filled with Bondo. A few patches later and other than a part of the original CFR number missing you can't tell. Looks good Good luck with the restoration.
