ER110S-G
ER110S-G is a copper-coated ultra-high strength low alloy solid wire for GMAW (MIG/MAG) and GTAW (TIG). It is designed for welding 110ksi grade high-strength low-alloy structural steels, providing superior mechanical strength, excellent crack resistance and stable joint performance for ultra-heavy load structural applications.
Features
• Precision low-alloy formula provides ultra-high tensile and yield strength, fully meeting the welding standard requirements of 110ksi high-strength steel structures.
• Excellent resistance to hydrogen-induced cold cracking and structural brittleness, adaptable to high-stress and high-rigidity welding components.
• Stable arc combustion, low spatter output and smooth uniform weld bead, bringing easy operation and high-efficiency welding construction.
• Strictly controlled chemical composition and stable welding process tolerance, ensuring consistent and reliable mechanical properties of welded joints.

Welding Precautions
• General-purpose 110ksi ultra-high strength welding wire; not applicable for heat-resistant steel, cryogenic steel or stainless steel welding.
• Remove all oil, rust, scale and moisture from the groove and surrounding base metal to avoid porosity and slag inclusion defects.
• Adhere to strict preheat and interpass temperature control during welding to reduce residual stress and prevent cold cracking.
• Professional post-weld heat treatment is required for thick-wall and ultra-heavy load components to optimize weld mechanical performance.
• Prohibited for long-term high-temperature, ultra-low temperature and strong corrosive service working environments.
