welding machines might not behave the same this week as it did last week.
proper transitioning between passes is important for visual aspects of inspection and when a weld would be subjected to cyclical loading.
mixing wide weaves with stringers when capping off a coupon won't be accepted by some inspectors.
controlling undercutting is easier when running stringers than when weaving, but weaving makes slag easier to remove.
overhead @ 135 AMP produced no spatter, but overhead @ 150 AMP produced significant spatter and undercutting.
when rod angle is not perpendicular, penetration is strongest directly inside acute side of rod angle.
weaving produces steep slopes. always run a stringer through butt side before weaving through a groove.
it helps a bit to keep track of rod depletion when puddle formation cannot be seen.
no spatter at all when welding vertical @ 120 amp, but lots of lumps.
no spatter at all when capping off, cause of spatter may or may not be related to arc length.
150 amp, booth 8, aisle 115, BCIT: huge spatters when passing through latter half of bevel; no spatter as soon as rod exits bevel
best rod angle seems to be upward 45 degrees and forward perpendicular with no sideways tilts.
if you see a sign that says "family restaurant & lounge", someone is trying to have their cake and eat it too.
the world kicked itself in the head when "Twitter Jockeys" became a full time profession.
