Kumwell Exothermic Welding
Kumwell exothermic welding connections have been tested, inspected and qualified for successfully meeting qualifications and international reliable standards of UL 467 – Standard for Grounding and Bonding Equipment, IEEE 837 – Standard for Qualifying Permanent Connections used in substation grounding, IEC 62561-1:2012 Lightning Protection Systems Component (LPSC) for Connection Components and ISO 9001:2008 Quality Management System.
In addition, Kumwell emphasizes on product safety with our exothermic welding process. For the starting and weld metal powder, we ensure that the material contains non-toxic, heavy metal, and non-self-ignite. Also when heated the weld metal powder for bonding connections, it gives steady burn without pop and fire out, consistency of color, no slag and porosity.
