Pipeweld 70S-6

Pipeweld 70S-6 is a copper‑coated solid MIG wire designed for downhill circumferential GMAW on pipe grades up to 70. It targets pipeline, compressor station and related oil‑and‑gas applications where clean welds are required.

Key Features

• Copper coating for improved feeding and reduced spatter
• Optimized chemistry to minimise post‑weld rework
• Available in multiple drum sizes with reinforced corners for easy handling
• Excellent feeding performance for high‑speed welding and long feed distances
