hey

how do i get rid of undercut on a t fillet weld?

----------------------------------------------------

usually undercut is from too long an arc,too much amperage, wrong rod angle, to fast travel speed, or combination of some or all of these.

try using a much tighter arc...tight enough so the you can feel the tip of the rod rub.

then work on the rest of the things too.

thanks for posting your welding question,

jody
