Weld Star Dual Core 70 M (Seamless) Wire [16kg Spool]

The Weld Star Dual Core 70 M is a premium seamless metal cored tubular wire designed for high productivity welding of mild and medium tensile steels. Unlike standard folded wires, its seamless construction provides an impenetrable barrier against moisture, virtually eliminating the risk of hydrogen induced cracking.

This wire is the "productivity powerhouse" of the Weld Star range. It offers the ease of use of a solid wire but with the significantly higher deposition rates and travel speeds of a cored wire. It produces a stable, spray like arc with virtually no spatter, drastically reducing post weld clean-up and grinding costs. Precision layer wound on 16kg spools, the Dual Core 70 M is the definitive choice for heavy structural steelwork, shipbuilding, and high duty robotic welding cells where uptime and weld quality are critical.

Key Features

Seamless Technology: Total protection against moisture pick up ensures ultra low hydrogen weld metal (<4ml/100g) and long term storage reliability.

Higher Deposition Rates: Outperforms solid wires by up to 20-30% in metal recovery, allowing for faster travel speeds and shorter production cycles.

Low Spatter & Easy Clean: Exceptional arc stability in the spray transfer range results in a clean finish that requires minimal grinding.

Excellent Gap Bridging: The metal cored design handles poor fit ups better than solid wire, making it ideal for large scale structural assemblies.

Optimised for Automation: Consistent wire feeding and a stable arc make this wire perfect for robotic and mechanised welding systems.

Superior Mechanicals: Delivers high impact toughness at low temperatures (typically down to -40°C).
