Welding electrodes Kjellberg Prima Blue

Description

PRIMA BLUE is a high-quality stick electrode designed for welding unalloyed mild steels. It offers excellent welding performance in all positions, making it suitable for both production and repair work across the steel fabrication industry, workshops, and general metalworking applications. The electrode is very easy to handle and ensures a stable welding process. It features good gap-bridging capability, easy arc ignition and re-ignition, and produces very low spatter. These properties make it a reliable choice for both professional welders and everyday workshop use. PRIMA BLUE produces smooth weld beads with a finely rippled surface. It performs well even when welding slightly rusty or primed base materials, maintaining good weld quality under less-than-ideal surface conditions. The slag formed during welding is easy to remove, helping to speed up post-weld cleaning. This electrode is widely used for welding structural steels, pipelines, pressure vessels, shipbuilding components, cast steel parts, and reinforcing steel.

Kjellberg

The Kjellberg Finsterwalde group of companies originates from the former Kjellberg Finsterwalde Elektroden und Maschinen GmbH, founded by Swedish inventor and entrepreneur Oscar Kjellberg. In 1908, he received a German patent for the coated electrode, which initiated the development of modern welding. Operating in Germany and continuing the tradition under the name Kjellberg Finsterwalde, the company has spent decades building its position in the industry. Today, the companies within this group are among the world's leading manufacturers of welding electrodes, welding technologies, and plasma cutting systems.
