Abrasion Resistant Wear Pipe - General Welding Data (Ultima 601 Pipe)
Welding I.D. Hardened Wear Pipe
Our Ultima 601 induction hardened wear pipe is manufactured utilizing
specialized thermal techniques that develop carbide hard inside diameters while
maintaining ductile hardened outside diameters for toughness. Unregulated
intense heat (from cutting, or welding operations) may "draw back" the hardness
of the I.D., resulting in diminished resistance to abrasive wear. Please exercise
all caution to minimize heat transferred to the inside of the diameter of the pipe.
Joint Prep: Remove all slag and discolored material after cutting, i.e. follow
standard welding procedures for preparing clean smooth joints free of
contaminants. Bring parts to contact, allow 3/16" max. root opening. For spaces
greater than 1/16" increase leg of fillet weld by the amount of the opening.
Pre-Heat / Inter-pass Temperature: If any of the parts are colder than room
temperature (70°F), preheat weld zone and 6" of adjacent material to 100°F for
sections heavier than 1" thick cross-section call for guidelines. Do not exceed
450°F inter-pass temperature.
Electrodes: E7018 electrode, (1/8", or 3.18mm). Smaller diameters may be
used. Follow Standard Low Hydrogen Method. Utilize sound welding practices
and only use experience welders familiar with welding pipe and related products.
General Guidelines: Place welds to the outside of the pipe wall O.D. Avoid
heat buildup on the I.D. Maintain smallest practical weld bead. The bead length
should not exceed 5" to 6". Allow the pipe to cool before applying additional
beads. Use stringer bead and avoid a weave pattern. Use multiple passes (5 to
6 passes for 3/8" filet welds - 10 to 12 passes for 1/2" filet welds.
Avoid Butt-Weld Construction
Caution: Induction hardened pipe contains retained internal stresses. Never cut
this product lengthwise, as serious injury or property damage might result.
Employ all standard guidelines appropriate to welding hardened alloy materials.
Always use experienced welders. |
