a newbie question 'bottom-up'?

admin

greetings,thanks for pointing a newbie student in the right direction. I'm trying to understand the term 'bottom-up' welding. I can't find a reference to it in my lincoln handbook or any of my training manuals. The context would be on welding pipe. thanks
Reply:How and who mentioned it? If it was someone who was trying to explain something, they probably meant Vertical-UP. Unless they forgot the word vertical...tough to say.John -  fabricator extraordinaire, car nut!-  bleeding Miller blue! http://www.weldfabzone.com
Reply:I think bottom up means start at the center on the bottom and go up both sides.  There is no verticle down in this method.I am not a pipe welderDavid
Reply:You can run vert down on some pipe....._________________Chris
Reply:thank you for the information. vertical up would make sense in the context of welding pipe resting in a horizontal position. It sounds like someone was simply using non-traditional nomenclature.very helpful.
Reply:Nice stage name.. ...zap!I am not completely insane..Some parts are missing Professional Driver on a closed course....Do not attempt.Just because I'm a  dumbass don't mean that you can be too.So DON'T try any of this **** l do at home.
Reply:"bottom-up" probably means 5G uphill progression.Then again, there have been pipe welders go through the program at school who claim to weld better after having a few (alcoholic) drinks.... I guess that would give "bottom-up" welding a whole new meaning...Visit Tensaiteki.com
