DIN 8555: E 6 - UM 55 - G

EN 14700: E Fe 8

Packaging: basic

Welding current: ~/=+

Welding positions: PA, PB, PF

The weld metal, although having high hardness, is tough and resistant to abrasive wear and impact. For the armouring of machine and structural parts which are also subject to impact stresses due to increased wear. For the welding of excavator teeth, shrinking plates, ploughshares, hammers, hammer drills and mills, pulling, pushing and pressing tools, crushers, mixing machines. Can be used for welding without interlayers on new and worn parts.
