Joining of -and buffer layers on problem steels

EN ISO 14700 (E Fe10)
A5.4 (E 307-26)

General description:

Lastek 807 is a high strength, ductile, crack resistant electrode designed for welding problem steels such as high carbon and crack sensitive tool steels or manganese steel. Heat resistant up to 850°C. Rust proof. Recommended for hardfacings; High resistance to wear and heavy shocks. Excellent weldability in all positions, except vertical down.
High recovery (160 %).

Typical applications:

Joining of highly alloyed and difficult to weld steel. Surfacing and repair of excavators buckets. Joining and surfacing of rails and steel with 14 % manganese. Cushion layer for hard facings. Surfacing of rollers, crane-wheels, etc.

Tips:

Keep the arc as short as possible. Electrode position almost 90° to the workpiece. For welding 14% Mn-steel, keep the temperature of the workpiece below 350°C.
