Böhler FOX BVD 85 E8018-G Vertical-Down Pipe Electrode
Description
Basic vertical-down electrode for medium-strength line pipe
The Böhler FOX BVD 85 is a basic-coated stick electrode for vertical-down welding of large-diameter pipelines and structural work. Böhler describes it for filler and cover pass welding in pipeline construction, with a crack-resistant, tough, low-hydrogen deposit and a deposition rate 80 to 100 % higher than vertical-up welding. Its classifications include AWS A5.5 E8045-P2 H4R and E8018-G H4R and EN ISO 2560-A E 46 5 1Ni B 4 5 H5. Of the BVD 85, 90 and 100 electrodes on Böhler’s webshop it carries the lowest strength class, suited to pipe grades up to X65 and, in brackets on the data sheet, X70.

Base materials and sour-gas use
Listed base materials are S235J2G3 to S355J2G3, L290NB to L450NB, L290MB to L450MB and P235GH to P295GH, and API 5L grades A, B, X42, X46, X52, X56, X60, X65 and X70 in brackets. The data sheet says FOX BVD 85 can be used in sour gas applications, with HIC testing according to NACE TM-02-84 and SSC values available on request. Impact values appear on the data sheet in a layout that mixes temperatures, so request the TÜV certificate for toughness figures at a specific test temperature.
Notes on the vertical-down technique
Vertical-down welding with a basic electrode is fast but depends on a clean joint and a steady travel speed, and it is normally used for the fill and cap passes after a cellulosic or other root run. Keep the interpass temperature below 175 °F as recommended, redry only if needed at the stated temperature, and qualify the procedure for the pipe grade. Because this data sheet is the 2017 edition, confirm current classification with Böhler when the project specification is strict.
When ordering, state whether the electrode will be used with a cellulosic root pass, because the fill and cover electrode should be selected together with the root electrode in the qualified procedure, not separately.

About brand
Böhler Welding is the welding consumables brand of voestalpine Böhler Welding, part of the voestalpine group, with a portfolio that covers stick electrodes, TIG rods, solid wires, gas-shielded and self-shielded flux-cored wires and submerged-arc wires and fluxes. The company states more than 100 years of experience. Seven Star LLC, an independent supplier in Muscat, lists Böhler Welding consumables and welding machines, including pipeline electrodes, and sources Böhler Welding consumables for fabricators and pipeline contractors.
Böhler Welding product groups
Beyond the consumables above, Böhler Welding lists strip cladding, wire arc additive manufacturing, metal powders, arc spraying cored wires, ceramic weld backing, brazing consumables and welding automation such as orbital welding and collaborative robots. The pipeline range includes cellulosic FOX CEL electrodes and basic vertical-down FOX BVD electrodes for large-diameter line pipe.
Ordering Böhler Welding consumables: what we need
Give the product name, the AWS or EN classification, the diameter and length, and the packaging you need. For pipeline electrodes also state the pipe grade, wall thickness, welding position and whether sour-service test values are required, because the Böhler Welding data sheets note that some test values are available on request.
