Hi,I want to build a grape vine arbor from metal pipes. I have no experience welding, I took the welding class at the local community college and my experience is just what I got from the practice at the class. I have an Hobart Handler and I'm going to use flux core wire. So, back to the question, I need to weld 2x 1/2 pipes on top of 1" pipe  (the corner of the arbor), something like this:How do I cut the pipes to be able to weld them together easy?Thanks!
Reply:I would cut the 1/2“ pipe ends at a 45-degree. Then saddle the 1“ pipe with a hole saw the same size as the outside of the 1/2“ pipe. Then I would see about filling in the gaps on the sides.  Or beat the sides in a little to fill with weld.Don’t pay any attention to meI’m just a hobbyist!CarlDynasty 300V350-Pro w/pulseSG Spool gun1937 IdealArc-300PowerArc 200ST3 SA-200sVantage 400
Reply:Hello ioan, along the lines of what CEP is suggesting here's a sketch of an approach that you could consider as well. Best regards, Allan Attached Imagesaevald

Reply:Thanks everyone for the advice.While looking for the best price for pipes, I ended up buying square tubing from the local scrap metal place which made my job easier. Part of the structure is done:
Reply:why dont you weld it on the ground then just stand it up, much safer than tippy toes on that ladder....and drill a drain hole for water at the bottom of each piece going vertical...and undercoat all the ends that you put in the ground to protect from rusting out....Of all the things I lost I miss my mind the most...I know just enough about everything to be dangerous......You cant cure stupid..only kill it...
Reply:X2 that looks pretty sketchyVantage 300 kubota ,miller 304 xmt ,lincoln ln 25 pro , ranger 305 G, plenty of other tools of the trade to make the sparks fly.
Reply:Square tube is definitely easier for a beginner. Now, we would like to have you around for a while with no injuries. Standing on top of a ladder is a no no. Welding on the ground is safer for a beginner. If you don't have funds for a table ,stands, saw horses, use the tires ,stack patio stones on top of each other, and use ladder rungs for supports to rest the pieces on. Use squares and not a level. It is much easier to build on ground. Even a old fold up ironing board will work or a cheap table saw will be handy to work off of.  Since you are beginning SAFETY is where you should start. A pair of work boots will pay for themselves before you burn holes in your socks. A connected garden hose would help putting out some burning grass. I'm only pointing out some suggestions. After doing this for a few years safety is burned into my head and only passing it on. Play safe and have fun.
Reply:Yeah, I know it looks dangerous, but my wife was always next to me holding the ladder (except for that moment to take the picture). The bottom part of the column that's in cement is coated against rust:http://i.imgur.com/qG68T57h.jpg... for water, I'm going to weld a cap on top of each column, should that be enough?
Reply:''  but my wife was always next to me holding the ladder''  So, you are on top wife below ,sounds good to me.    However SHE could be getting showered with sparks. That's a heck of a wife you have.

Reply:Now that's a much better picture. A TALLER ladder, really safer. Best idea to leave the tough stuff to wife and daughter.     Weld looks decent , practice on bench where you are stable and you can flip  material around for a better position. Get the wife interested too. This way you can buy her welding goodies for gifts !   Play safe !
