Hi Owen .

Yes for an amateur it is hard to see stick welding as a good alterative .
but I know Pipefitter welders who can out preform any aircraft welder ,and they are
only 2nd year apprentices .
Aircraft standards are not very high , when it comes to welding .
Anybody can weld , if you dont mind under cut , cold lap ,or inclusions .
I see them all the time on aircraft .
If you want to serve a 4 yaer apprenticeshipe with 6 weeks schooling every
year then you to can become a welder in this Province .
What people call welding on their own planes , would fail arround here .
For the amateur welder Oxy is the easiest way to go .
If you are a welder then Stick , MIG ,or TIG are a better choise .
I repeat Aircraft Standards are not very high , when it comes to
Welding Amateur Built Airplanes .

Take the time to learn the right way to weld . Take a course .

Gordon
