Consumables

For use in the welding of critical piping systems where internal obstructions cannot be tolerated or in welding of pipe, tube and other joining areas where uniformity and smooth root bead is required. A ROBVON CONSUMABLE INSERT becomes an integral part of the initial root-weld bead. It insures complete penetration and smooth tying in of the insert and adjacent pipe, tube or fitting ends. The ROBVON CONSUMABLE INSERT reduces flow restriction within the bore to a minimum and eliminates root-bead cracking due to notch-effect and abrupt change in cross-sectional weld area.
