39113 - Bohler HL 51 L-MC 1.4mm Metal Core Welding Wire 15kg

Maximize Welding Productivity with Bohler Seamless Technology

The Bohler HL 51 L-MC Metal Core Wire represents the pinnacle of cored wire technology, designed specifically for fabricators who demand efficiency without compromising on quality. Unlike traditional folded wires, this 1.4mm wire features a seamless copper-coated design. This innovative manufacturing process hermetically seals the metal powder core inside a continuous steel tube. The result is a consumable that is completely impervious to moisture absorption, drastically reducing the risk of hydrogen-induced cracking and porosity, even in challenging storage environments.

For industrial workshops and manufacturing plants, the HL 51 L-MC offers significant advantages over solid wires. It provides a wider arc and deeper penetration profile, which helps eliminate lack-of-fusion defects. The high deposition rate allows welders to lay down more metal in less time, increasing travel speeds and overall throughput. This makes it an exceptional choice for heavy structural steel fabrication, machinery construction, and automotive components where cycle times are critical.

Operators will appreciate the smooth running characteristics of this wire. It produces a stable, spray-like transfer with minimal spatter, meaning less time is spent on post-weld grinding and cleanup. The 1.4mm diameter is optimized for medium-to-heavy plate thicknesses, allowing for high-amperage welding that drives productivity. Whether used in manual hand-held torches or high-speed robotic cells, the Bohler HL 51 L-MC delivers consistent, high-quality results that professionals trust.
