Kobatek 345
gENERAL DESCRIPTION
A special electrode for welding steels having limited weldability, such as manganese steels, hardenable steels and others. It is an AC/DC electrode giving a non-magnetic and work hardenable stainless steel deposit containing Cr/Ni/Mn/Mo. The tough weld metal is able to absorb high welding stresses which is very important for achieving crack-free welds.

PROCEDURE – A
High Amperage Welding
High amperage welding for heavy sections and large parts, maximum deposition rates.
PROCEDURE – B
Low Amperage Welding
Low amperage welding for small sections and parts which must not be overheated, minimum dilution and low heat input.
