Bohler Fox BVD 85 (Basic vertical down) Pipeline Steel Stick Electrodes

Basic electrodes for vertical-down welds of large diameter pipelines and for structural work, suitable for filler and cover pass welding in pipeline construction. Deposit is extremely crack resistant, and features high toughness and a very low hydrogen content. Deposition rate is 80-100% higher than for vertical up welding.

The weld deposit of Bohler FOX BVD 85 shows an ideal combination between high strength and cryogenic toughness down to –50°C (–58°F). Special design and development work has enabled this electrode to provide exceptional striking characteristics and the avoidance of start porosity on cover (cap) passes. Due to this and the good welding characteristics this special basic electrode offers easy handling even under field conditions.

Features

Certified under AWS A5.5 (typically as an E8045-P2 H4R type) and EN ISO standards for high-strength pipeline steels. 
Ensures an ultra-low fusible hydrogen content (HD ≤ 4 ml/100g), greatly reducing the risk of hydrogen-induced cold cracking. 
Ideal for filler and cover passes on large-diameter cross-country pipelines and demanding structural joints requiring high mechanical strength and toughness. 
Offers smooth vertical-down progression, stable arc characteristics, and easy slag removal.
