79482 - UTP 614 Kb E7018-1 Welding Rod 2.4mm 4kg

Premium Basic Coated Electrode for Critical Applications

The UTP 614 Kb is a high-performance basic coated stick electrode designed for the welding of unalloyed and fine-grained structural steels. Classified as an AWS E7018-1 H4, this electrode is engineered to deliver superior metallurgical properties, making it the preferred choice for industries requiring high integrity welds, such as offshore construction, shipbuilding, boiler fabrication, and pressure vessel manufacturing. The internal SKU UTP614KB-2.4 identifies this specific 2.4mm diameter variant, packaged in a convenient 4kg format, optimized for professional industrial use.

One of the defining characteristics of the UTP 614 Kb is its exceptional crack resistance. The basic coating formulation ensures a weld metal with very low hydrogen content (typically less than 4ml/100g), significantly reducing the risk of cold cracking (hydrogen-induced cracking) in thick sections or restrained joints. This makes it particularly suitable for welding steels with higher carbon contents or those susceptible to cracking. Furthermore, the electrode exhibits outstanding impact toughness at low temperatures, maintaining ductility down to -40°C, which is critical for structures exposed to harsh environmental conditions.

From a processing standpoint, the UTP 614 Kb offers a stable and concentrated arc that provides deep penetration and reliable fusion. The slag system is designed to be easily detachable, often self-releasing, which reduces post-weld cleaning time and improves productivity. The 2.4mm diameter is versatile, allowing for precise control in root passes and thin-wall applications while still being capable of filling joints in multi-pass procedures. It operates best on Direct Current Positive (DCEP), ensuring a smooth transfer and high-quality bead profile.

In summary, the UTP 614 Kb represents a top-tier solution for welders and fabricators who cannot compromise on quality. Its combination of mechanical strength, low temperature toughness, and operator-friendly characteristics ensures that it meets the rigorous demands of modern engineering standards.
