How do you cap the bottom (overhead) of pipeline using 5/32 5+.

Note: This is not a smart a$$ answer. You weld the bottom, just like you do the top, just upside down.

how is that

If you are using a side to side on top, then do a side to side on the bottom. If you are doing a circle on the top. then do a circle on the bottom. Travel speed will vary as you hit the sides, but keep the travel speed on the bottom, about the same as you do on the top.
Just upside down.

what do you think the heat difference from toop to bottom should be
Parent - - By dbigkahunna (****) Date 08-16-2008 20:58
None. You weld the bottom just like the top. Same heat same motion.

probabaly to hot , & going to slow , try horse shoe motions ( coming back towards you ) & just tap the bevels .
