Stick Electrodes for Steel Construction

2022-06-09 | 

What makes a stick electrode suitable for welding steel construction? It requires a good bead appearance, easy to remove slag, and resistance to hydrogen-induced cracks.

A low hydrogen content and a moisture-resistant coating are securing a good and safe weld quality and enable efficient welding processes. Offering lots of years of experience producing stick electrodes we profit from valued know-how and long-term product development.

What do we want to offer you?

  • High-quality filler metals for demanding industries
  • Less time for preparation with our ready-to-weld products
  • Safe welding with no repair welds
  • Welding whole shifts without re-drying

Unalloyed, for strength from 380 to 460 MPa

Product EN ISO AWS
FOX EV 47 E 38 4 B 4 2 H5 E7016-1 H4 R
FOX EV 50 E 42 5 B 4 2 H5 E7018-1 H4 R
FOX EV 55 E 46 5 B 4 2 H5 E7018-1 H4 R

Particularly suitable for general steel construction in buildings, structures, and plant engineering. In detail, the stick electrodes convince with the following advantages:

  • Basic coated electrode engineered for high-quality welds:

    • For steels up to 380 MPa yield strength
    • Very ductile weld metal with toughness properties down to -40ºC.
    • Crack- and ageing resistant and thus especially suited for rigid welds with heavy seam cross sections
    • Good weldability in all position except for vertical-down.
    • Welding in steel construction, boiler and tank manufacture, vehicle construction, shipbuilding, and machine construction.

  • Basic coated electrode engineered for high-quality welds:

    • For steels up to 420 MPa yield strength
    • Excellent strength and toughness properties down to -50ºC.
    • Good weldability in all position except for vertical-down.
    • Suitable also for welding steels with low purity and high carbon content.
    • Welding in steel construction, boiler and tank manufacture, vehicle construction, shipbuilding, and machine construction. Especially suitable for off-shore construction.

  • Basic electrode for high-quality joint welds with higher strength and toughness properties:

    • For steels up to 460 MPa yield strength
    • Low-temperature ductility down to –50º C.
    • Excellent weldability in all positions except vertical-down.
    • Suitable for welding in steel construction, boiler, tank, container and vehicle construction, shipbuilding and mechanical engineering.

Ni and Ni-Mo alloyed products with a strength of 460 and 550 MPa

Product EN ISO AWS
FOX EV 60 E 46 6 1Ni B 4 2 H5 E8018-C3 H4 R
FOX EV 65 E 55 6 1NiMo B 4 2 H5 E8018-G H4 R / E8018-D1 H4 R

The Ni and Ni-Mo alloyed products from Group 2 are particularly suitable for steel construction with higher strength and toughness requirements, such as in bridge construction, for offshore installations and for armored steels. The advantages of the individual stick electrodes include:

  • Basic coated, Ni- alloyed electrode with excellent mechanical properties, particularly high toughness and crack resistance:

    • For steels up to 460 MPa yield strength
    • For higher strength fine-grained constructional steels.
    • Suitable for service temperatures at –60ºC to +350ºC.
    • Very good impact strength in aged condition.
    • Easy weldability in all positions except vertical-down.

  • Basic coated electrode with high ductility and crack resistance, for high- strength fine grained steels:

    • For steels up to 550 MPa yield strength
    • Ductile down to -60ºC.
    • Resistant to ageing.
    • Easy to handle in all positions, except vertical-down.
    • BÖHLER FOX EV 65 can be used in sour gas applications
