880-035-36 - Weld Mold 880 Universal TIG Rod .035" - 10lb Tube

Premium Universal Maintenance Alloy for Critical Repairs

The Weld Mold 880 TIG Rod (.035" diameter) is a high-performance specialty alloy designed specifically for the Maintenance, Repair, and Operations (MRO) sector. Packaged in a 10lb tube, this rod is engineered to solve the most complex metallurgical challenges faced by industrial welders. Unlike standard fabrication wires, the Weld Mold 880 utilizes a proprietary chemistry that produces a balanced austenitic-ferritic microstructure. This unique grain structure provides exceptional resistance to cracking, even when welding under high restraint or on base metals with poor weldability.

With a tensile strength reaching approximately 120,000 PSI and high elongation values, this alloy offers a combination of strength and ductility that is unmatched in the industry. It is the ideal choice for joining dissimilar steels, such as welding stainless steel to carbon steel, or attaching tool steels to mild steel backings. The 0.035-inch diameter is particularly useful for precision applications, root passes on smaller components, or repairs on thin-walled sections where heat input must be strictly controlled to minimize distortion.

Technical professionals appreciate the Weld Mold 880 for its ability to act as a universal problem solver. It is frequently used as a cushion layer or buffer pass before applying hardfacing alloys, preventing the hardfacing from spalling off the base metal. Additionally, its resistance to heat and corrosion makes it suitable for repairing shafts, gears, and equipment subject to harsh operating environments. When the exact composition of a broken part is unknown, the Weld Mold 880 is the safest and most reliable specification to ensure a sound, defect-free weld.
