ESAB Welding & Cutting Products has introduced PIPEWELD 78LH FLUX, a low hydrogen flux for longitudinal or spiral welding of pipeline steel grads, using multi-wire submerged arc welding processes.
A new flux formulation and production process enables PIPWELD 78LH FLUX to meet the H4 classification of ≤ 4ml of diffusible hydrogen per 100g of weld metal as produced.
The product’s low hydrogen formulation and moisture resistance enables coating within a few hours after welding, improving throughout.
“ESAB tested PIPEWELD 78LH versus competitive fluxes and the previous version of OK Flux 10.77 and proved that it reduces moisture pick-up and diffusible hydrogen levels,” said Halinson Campos, Product Business Manager of Filler Metals, ESAB.
