Home Catalog Stick Electrodes Maintenance and Repair Solutions Z-2911 – Zika Industries Ltd.

ALL TYPES OF STEELS WITH VERY HIGH STRENGTH

 

DESCRIPTION

A low-Hydrogen electrode especially designed for general maintenance; welding cast steel and low-alloy steel. The welding material has medium to high tensile strength as well as very high impact strength at -46°C.

Easy ignition and smooth quiet arc with good penetration.

APPLICATION

  • Unidentified steels.
  • Joining dissimilar steels.
  • Tool steels.
  •  Heat treatable or quenched and tempered steels.
  •  High carbon steels.
  •  Spring steels.
  •  Manganese steels.
  •  Stainless steels etc.
  •  Wear resisting  build-ups on clutches , gear wheels, shafts etc.

 

Extracting broken bolts:

The Z-2911 electrode creates an especially strong welding material resistant to twisting stress. A quiet arc-ensures a spatter less weld. The electrode should have smaller diameter then that of the hole. Point welding should be constructed one on top of the other to the height at which a nut can be welded on top. Slag should be cleaned, and it is advisable to wait until cooling; then the bolt should be turned and released by using the appropriate wrench.
