in a previous video, i focused on only the root pass on a 6 inch schedule 80 6G test.
showing the importance of feathering tack welds, techniques, arc shots, and a lot more...
that video is called 6g Weld test 6010 Root if you are interested.
if you are only having issues with the root pass, that video should help.
this video will show this brief clip of the 6010 root pass and then show the 7018 1/8"
fill and cap
for both 6010 root and 7018 fill cap, We used the ESAB rebel 285
85-90 amps for the 6010 root and...
105 amps for the 7018 fill pass and 115 amps for the stringer cap.
3/32" gap with 3/32" land was used with 30 deg bevels
For the first fill pass with 7018 we used 105 amps
and we will crank that up a bit for the 2 bead stringer cap
lots of options on the menu of the 285
when you are in stick mode, you select either 6010 6011 or all other electrodes.
but there are also a couple of other settings one of which is hot start
that is really helpful for preventing porosity on starts as well as in preventing sticking
the rod. but there is also arc force.
so for 7018 generally speaking, you set that to around 30% or so.
for a nice buttery arc.
105 amps for that first 7018 pass.
the root pass on this weld has been ground smooth but that is not always allowed on a
test.
i have taken tests where I was allowed to use a grinder.
Ive taken tests where i was only allowed a file
i have taken tests where i was only allowed to use a grinder to feather the tacks and
then the grinder got locked up...so its all over the board.
be prepared to not be able to use a grinder
This is my good friend andrew cardin doing the welding today...
