Pipeline Welding Downhand Downhill Welding. The best procedure for welding high strength pipelines is therefore to use cellulose electrodes for the root pass and basic vertical down electrodes for filling and capping passes. Over 12 inch LH will win the race.

Impact toughness properties which are very good may be met with modern cellulosic electrodes.

The best procedure for welding high strength pipelines is therefore to use cellulose electrodes for the root pass and basic vertical down electrodes for filling and capping passes. The pipeline weld is almost always all downhill from start to finish. Some E6013 type electrodes would also work dow. Downhill welding techniques are used for welding pipeline whereas uphill welding is used for welding refinery piping systems.
