Description: CHE42 is an electrode covered with lime-titanium type coating for welding mild
steel. It is able to provide excellent performances in welding . The weld metal is
formed in smooth and pleasing
appearance. It can be used for all position welding by both AC
and DC power sources and for welding of various kinds of joints.
Applications:
Suitable for welding of steels with normal strength, such
as ship structures, machineries and pipes, etc.
