Elétrodo básico de baixo hidrogénio ESAB EB 150 2,5 mm, embalagem de 4,3 kg

With a typical impact strength of 140 J at -40°C, the ESAB EB 150 electrode delivers exceptional toughness for critical low-temperature applications. This 2.5 mm basic low-hydrogen electrode, supplied in a 4.3 kg pack, is engineered for high-integrity welding across structural steel, shipbuilding, pressure vessels, and pipe welding.

Overview

The ESAB EB 150 is a premium basic-coated electrode classified as AWS E7018 and EN ISO E 42 4 B 42 H5. It is designed for welding in all positions except vertical down, with a hydrogen content below 5 ml/100g to minimize the risk of cold cracking. The electrode operates on DC+ or AC with a minimum open-circuit voltage of 50V, offering flexibility in various workshop and field environments.

What stands out

• Ultra-low hydrogen content (H5) ensures crack-resistant welds on high-strength steels.
• Excellent impact toughness down to -40°C, ideal for Arctic and cryogenic service.
• All-position capability (except vertical down) for versatile joint configurations.
• Stable arc with smooth metal transfer, producing clean, slag-free weld beads.
• Re-dryable coating (300–350°C for 2 hours) for reliable performance after storage.
