I have been having a problem with undercut while in horizontal position the bead looks good its just a touch of undercut is present i am using a 7018 rod at about a 45 drag angle and insted of a weave using a counterclockwise circlular motion and im still having undercut im not sure why. Any thoughts are helpfull

What kind of joint/weld?

[Luke686]

fillet weld pretty sure if that sounds right i get groove and filet confused

[weldin mike 27]

If it looks like this, all you have to do with a 7018 is put the rod in and hold a nice tight arc. You don't need any manipulation with that rod, in that position. Search "welding tips from Bubba" for a good video

Thank u i have watched it i think i need to use a better rod angle

Also watch the top toe of the weld wash up against the vertical surface as you travel along the joint and make sure to slow down hang around a bit longer so that it can fill in and not leave undercut. I agree with the other about running straight stringers and leave the weave alone.

I tried using a diffrent angle and no weave and they really improved

I was working on that this week and my instructor told me to use no manipulation. To have a 5 degree work angle pointing upward and 5 to 10 degree travel angle. Really allow for toe to crown to fuse together while welding it. My bend test did not break.
