摘要

ESAB Welding & Cutting Products has introduced Pipeweld 78LH Flux, a low-hydrogen flux for longitudinal and spiral welding of pipeline steel grades-such as X70 and X80-using multiwire SAW processes. A new flux formulation and production process allow the product to meet the H4 classification as produced, thereby containing up to 4 ml of diffusible hydrogen per 100 g of weld metal. Because of its low hydrogen formulation and its moisture resistance, the flux allows pipe producers to apply a coating within a few hours of welding.
