EN ISO CODE:
Maxfil-12P is an all position flux cored wire designed to meet pipe welding applications. The wire runs with both CO2 and Argon-CO2 gas mix, facilitates easy deposition of vertical-up stringer beads and provide flat to slightly convex contour with equal leg lengths and uniform sidewall wetting. The slag coverage is complete and designed for easy removal. The deposited weld metal contains very low diffusible hydrogen (<4ml/100gms of weld metal) and is of radiographic quality. Maxfil-12P is designed for single and multi-pass welding of low and medium carbon steels X42 to X60 grade pipes and similar strength plates like; SA-36, A/B/C/D grades of SA-283, A/B/C grades of SA-285, A/B grades of SA-414, etc.
