PRACTICE NAME |
PIPE FLAT POSITION |
|
PROCESS |
SMAW SCH 80 GTAW SCH 40 |
|
POSITION |
FLAT 1G PIPE |
|
FILLER |
SMAW E-6010 E-7018 OR GTAW ER-70S-6 |
|
MACHINE SETTINGS |
AS REQUIRED |
Technique: Set the proper amperage and tack weld two pieces of pipe with a 1/8 or 3/32nd root opening in 4 places as directed by Instructor. (Use size of electrode without flux or use filler wire 3/32).
Weld the pipe in the flat position by rotating and welding only the top section until the pipe is welded complete. Weld the root pass with E-6010 and the rest of the pipe with E-7018.
The Root pass should penetrate into the pipe a minimum of flush to a maximum of 1/8.
The weld should not extent past the original groove face more than 1/8 on each side.
The weld should not be more than 1/8 high on the face of the pipe.

Technique: Set the proper amperage and tack weld two pieces of pipe with a 1/8 or 3/32nd root opening in 4 places as directed by Instructor. (Use size of electrode without flux or use filler wire 3/32).
Weld the pipe in the Horizontal holding the indicated angle around the pipe, until the pipe is welded complete. Weld the root pass with E-6010 then use E-7018 to weld the rest of the pipe using the stringer bead technique. Weld beads from lower pipe (bottom) to top pipe.
The Root pass should penetrate into the pipe a minimum of flush to a maximum of 1/8.
The weld should not extent past the original groove face more than 1/8 on each side.
The weld should not be more than 1/8 high on the face of the pipe.

Technique: Set the proper amperage and tack weld two pieces of pipe with a 1/8 or 3/32nd root opening in 4 places as directed by Instructor. (Use size of electrode without flux or use filler wire 3/32).
Weld the pipe in the 5G Vertical holding the indicated angle around the pipe, until the pipe is welded complete. Weld the root pass with E-6010 then use E-7018 to weld the rest of the pipe using the weave bead technique.
The Root pass should penetrate into the pipe a minimum of flush to a maximum of 1/8.
The weld should not extent past the original groove face more than 1/8 on each side.
The weld should not be more than 1/8 high on the face of the pipe.
