PRODUCT SPECIFICATION
Modi Lastek 43
Special electrode for ground layer on cast iron
GENERAL DESCRIPTION
-
Modi Lastek 43 has been developed for the repair of
"unweldable" cast iron, where Ni base electrodes do
not give a solid bond. The special coating develops a
powerful cleaning action. The aggressive arc
penetrates through the oxidised or contaminated
surface and provides a perfect bond.
-
Modi Lastek 43 absorbs the carbon from the cast iron
and the deposit becomes hard and nonmachinable.
-
Modi Lastek 43 should be used as a buttering run in
the groove made with Lastek 1900.
-
The beads should not touch. The joint is finished with
electrodes such as Modi Lastek 40E, 42E or 41E.
APPLICATIONS
-
Welding all poor quality cast iron, reclamation on
ship motor blocks, oxidised furnace parts, repairing
foundry defects for colour match, first layer on cast
iron prior to hardfacing (spreader cones in brick
extrusion machinery, cast iron gears.)
