Multiple Pass Welding - MasterCraft 058-8194-4 Instruction Manual

Multiple pass welding:

• Butt weld joint: When butt welding
thicker materials, prepare the edges of
the material to be joined by grinding a
bevel on the edges of the metal pieces
being joined. When it is done, a "V" is
created between the two metal pieces.
In most cases, more than one pass or
bead will need to be laid into the joint to
(fig R)
close the "V"
Note: When using self-shielding flux core wire,
it is necessary to thoroughly chip and brush the
slag off each completed weld bead before
making another pass.
• Fillet weld joint: Most fillet weld joints on
metals of moderate to heavy thickness
will require multiple pass welds to
produce strong joint. The sequence of
lying multiple pass beads into a T fillet
joint and a lap fillet joint is shown
