2. Weld Bead
A weld resulting from a pass
Stringer Bead
Weave Bead

3. Passes
Weld Pass - A single progression of welding along a joint. The result of a pass is a weld bead or layer

4. Fill Pass Cover Pass Root Pass Hot Pass
Hot pass - one or two beads. But keep it open

5. Techniques Stringer (drag) (whip) Weave Circles crescent zig zag
box weave
double J

6. Progression (vertical)Up
deeper penetration
Higher deposit rate (lb/hr)
Use near 90 degree travel angle or slightly up
Down
faster (point to point)
less penetration for thin metal
less dilution
Use steep angle

7. Flat Position
Fillet/Groove - stringer or weave, split bead or wide weave

8. Horizontal
Fillet/Groove - stringers (small weave may be used in tight place)
Bead Placement - bottom to top

9. Vertical Fillet/Groove - weave (or whip but not straight stringers)
Root pass 6010 whip
Root pass 7018 straight stringer or weave (open closed)

10. Overhead Same as horizontal for Fillets
6010 open root whip for flat face and keyhole control
7018’s stringers
OH Butt Joints can be stringers or weaves
