Magnetism in welding: how to deal with magnetic blow
24 de noviembre de 2025
When welding ferritic steels, especially high-strength grades, magnetic blow can become a real challenge. This phenomenon occurs when magnetic fields interfere with the welding arc, causing instability, spatter, and sometimes making welding almost impossible.

Kemppi's advanced welding processes: MIG/MAG welding
One of the most important elements in developing welding equipment has long been improving welding processes and creating new process variations. Modern measurement and arc control methods have made a wide range of variations in the arc welding process possible. These advanced welding processes significantly improve welding production efficiency and weld quality. This article presents the special processes and operations developed by Kemppi for MIG/MAG welding.

Safety that keeps up with welders' challenges and changing risks
Welding safety has become increasingly demanding. The hazards at the arc remain constant, but modern working conditions mean exposure can accumulate over longer shifts and in tighter indoor spaces. As a result, welding PPE needs to be treated as both protection for the welder and proof of compliance. At Kemppi, welding safety PPE is designed and validated in practice through clear requirements, welder-led feedback, and verified compliance with EU PPE Regulation 2016/425, CE marking processes, and relevant EN standards.
