Can someone explain or direct me otherwise on a proper way to complete a vertical weld when you cannot access the pieces from below?I broke my snowplow ( ... again ...) and my choice is to either weld vertical from above or overhead.  it is a fillet weld if that makes a difference.my gut feeling is that it would be similar to welding flat, with regard to the arc force keeping the slag out of the weld, but how do you keep the pool from simply dropping out?i'll get some pictures tomorrow, cauz i'm gonna need some help with ideas on how to fix some other stuff on it as well.thanks in advance!mike
Reply:As with all SMAW, it's all about rod angle, arc length, and knowing how to read the puddle. Doesn't rally matter what position it is in, or where it is.

Reply:Bend your rod in a way that it will angle upward, may mean that you will only get use of about half the rod, but thats your best bet. So your holder and top of the rod will be pointing down to your weld area and the rod will be bent back on itself so you can travel upwar, Rod will basically be in a "U" shape. then just work it up the joint, it's not ideal but it will get it done. As above, just watch your puddle and come up the joint."Si Vis Pacem Para Bellum"Lincoln Idealarc 250 AC/DCMillermatic 251   Syncrowave 300   30A spoolgunLincoln MP210Hypertherm 45(2) LN 25(2) Lincoln Weldanpower 225 CV(4) SA200   1 short hood    SA250    SAM 400

Reply:you just have to bend your rod. I've welded in spots where I could only use about an inch of rod, talk about a pain in the butt. Sometimes I cut them off short so they aren't so wiggly.
Reply:i was able to get help and have my father-in-law hold it so that i can weld it flat.http://weldingweb.com/vbb/showthread.php?p=2024101if anyone was interestedthanks for the advice, though.  bending the rod would have been the way to go on this one.
Reply:Don't quite understand, on one hand you say you have to weld it in a position where you are above it and have to come up hill, understood it to be a fixed area that was a pain, now you say you can have your father in law " hold it" WTF, why didn't you just move it to a postion you could cope with in the first place."Si Vis Pacem Para Bellum"Lincoln Idealarc 250 AC/DCMillermatic 251   Syncrowave 300   30A spoolgunLincoln MP210Hypertherm 45(2) LN 25(2) Lincoln Weldanpower 225 CV(4) SA200   1 short hood    SA250    SAM 400
