Why Choose Seamless Cored Wires?

Engineered for reliability, performance, and safety in extreme conditions

Moisture Resistance

No seam in outer layer ensures excellent moisture resistance. Prevents hydrogen-induced cracking even in high humidity.

Lowest Diffusible Hydrogen

≤3 ml/100g deposited weld metal. Reduces preheating requirements and improves weld integrity.

Copper Coating

Improves feedability and ensures optimal current transfer for robotic and automated welding systems.

Stable Arc & Positioning

Closed tube design ensures extremely stable targeting point and excellent arc stability with low spatter.

Extreme Climate Performance

Weld reliably down to -60°C. Ideal for offshore, Arctic, and cold region applications.

IACS Approved

Certified by ABS, DNV, BV, LR, TÜV, and CCS for use in shipbuilding, offshore, and critical infrastructure.
