Where To Buy
Enquire about this product

OK 74.78 is an LMA AC/DC electrode suitable for welding high tensile steels used in low temperature applications. Good notch toughness down to -40°C. Suitable for enclosed welding and cladding of rails, when a hardness of ~ 250 HV is required. Also suitable for butt welding rails with tensile strength of 800-900 N/mm2. Due to low moisture content in the coating, this electrode is suitable when preheating cannot be applied.

Welding Invented

When our founder Oscar Kjellberg developed the world's first coated welding electrode in 1904, he launched a company whose innovation and uncompromising standards have helped create the history of welding itself. This legacy continues in the quality, performance, and continuous development of the covered electrodes we make today.
