Welding electrode 7018 MOST (orange) 2.5mm /2,5kg/ 0630701825

Universal welding electrode for demanding applications

The MOST 7018 (orange) electrode with a diameter of 2.5 mm is a proven choice for professionals and demanding users. It is characterized by very good parameters and is particularly recommended for welding structural steels and high-strength cast iron. It will find application in the shipbuilding industry, machine construction, and the railway sector – everywhere where high quality and durability of welded joints are required. Its basic coating ensures a stable arc and minimizes the risk of welding defects.

Properties and application

This electrode is dedicated to welding heavily dynamically loaded structures, making it ideal for use in machines and equipment exposed to vibrations and impacts. The ability to weld in all positions – downhill, lateral, vertical, and overhead – increases its versatility and allows for the implementation of various projects. It meets stringent quality standards (PN-EN 2560-A-E: E 42 4 B 42 H5, AWS A 5.1: E 7018) and has approvals from recognized certification institutions (ABS, BV, DNV-GL), which guarantees its reliability and safety of use.

Strength parameters and chemical composition

The MOST 7018 electrode provides high weld strength – the yield strength exceeds 440 N/mm², and the tensile strength is in the range of 510-610 N/mm². The elongation after fracture is over 24%, and the impact energy exceeds 47 J even at -40°C, which confirms its resistance to low temperatures. Chemical composition [%]: C=0.08, Si=0.60, Mn=1.00 affects the mechanical properties of the weld and its suitability for specific applications. Welding current can be direct or alternating, providing flexibility in choosing the appropriate power source.
