Mild and Low Alloyed Steel Electrodes

STAR GP-6013 electrodes

General purpose rutile electrode for welding of mild and low alloyed steel on-board. Strikes and re-strikes easily and is less effected by the rust and paint on steel surface to be welded. The re-striking ability makes it ideal for tack welding. The STAR GP-6013 can be used in all positions including vertical down and is therefore highly suitable for use in confined spaces. The electrode can also be used to bridge large gaps where plate or pipe assembly have poor fit up.

Applications range from tack welding of plate and pipes to complete welding jobs on light or heavy mild steel sections.

STAR GP-7024 electrodes

High recovery mild steel rutile electrode with recovery rate of 170 – 180% for welding in the flat and horizontal-vertical position. Designed specifically for mild steel, heavy fabrication welding where there is a need for large volume deposits to be laid using single or multi-pass techniques. This is an easy to use electrode employing either conventional to touch welding (contact with the base material) techniques. The STAR GP-7024, with its high welding speed and high deposition rate becomes specifically useful when there is a need for large steel replacements on-board or when doing sea fastening on-board heavy lifters.

STAR LH-7018 electrodes

High quality, superior all positional, low hydrogen, basic coated electrode that provides 120% metal recovery. For welding of unalloyed, low alloyed and yield point controlled steel, normally used in deck plates, hull plates and frames on-board. The extruded, moisture resistant electrode coating prevents moisture absorption during storage, thereby achieving low hydrogen levels and crack resistant welds. Welds are of smooth appearance, ductile and of high radiographic quality.

The electrodes are particularly suitable for welding heavy sections subject to high levels of resistance and for welding problem steels with high sulphur content. Recommended for unalloyed C: Mn ferritic steels with high sub-zero toughness requirements, EG: Charpy values down to –60ºC. CTOD values at –10°C. Used to best advantage for welding thick sections either on-board ship or in fabrication shops.

STAR LH-7016 electrodes

An easy to weld, low hydrogen basic coated electrode for welding of unalloyed, low alloyed and yield point controlled steel. Good positional welding properties. Vertical welding should be conducted in the upward direction.

Classification: AWS A 5.1 E7016

Type of current: AC, DC +

STAR LH-8018 electrodes

A superior, versatile, low hydrogen, basic coated electrode for welding of high temperature steel with up to 1% chromium and 0,5% molybdenum. The electrode coating is extra moisture resistant with a controlled iron powder addition.

Recommended where there is a need for resistance to hydrogen attack up to 330˚C and corrosive effects of processing high sulphur crude oil up to 450˚C. Also, for prolonged elevated temperature service up to 550˚C with reasonable degree of corrosion resistance in super-heated stream.
