TIG FILLER WIRE CIGWELD COMWELD 316LSI 1.6MM

Premium Stainless Steel TIG Welding Rod for Superior Corrosion Resistance

Product Overview

CIGWELD Comweld 316LSI is a premium low-carbon, silicon-enhanced stainless steel TIG filler wire designed for welding 316 and 316L austenitic stainless steels. The 1.6mm diameter makes it ideal for a wide range of general fabrication and precision welding applications where excellent weld bead appearance, smooth arc characteristics, and strong corrosion resistance are essential.

Key Features

• 316LSI Grade Composition – Low carbon content minimizes carbide precipitation and sensitization, preserving corrosion resistance in the heat-affected zone
• Silicon-Enhanced (Si) Formula – Higher silicon content improves weld pool fluidity, wetting action, and bead profile for a cleaner finish with fewer defects
• 1.6mm Diameter – Versatile size suited to light-to-medium gauge stainless steel sheet and pipe work
• Excellent Arc Stability – Smooth, consistent arc with minimal spatter for cleaner welds and reduced post-weld cleanup
• High Molybdenum Content – Provides superior resistance to pitting and crevice corrosion, particularly in chloride-rich or marine environments

Typical Applications

• Marine and offshore equipment
• Food, beverage, dairy, and pharmaceutical processing equipment
• Chemical processing plant and piping
• Pulp and paper industry components
• Architectural and structural stainless steel fabrication
• General maintenance and repair of 316/316L stainless steel components

Material Compatibility

Suitable for welding:

• 316, 316L, 316LN stainless steels
• 304/304L stainless steel (dissimilar joints)
• Cast stainless steel grades with equivalent chemistry

Why Choose Comweld 316LSI?

CIGWELD's Comweld range is manufactured to tight chemical and dimensional tolerances, ensuring consistent feedability, arc performance, and mechanical properties weld after weld. The low-carbon "L" designation reduces the risk of intergranular corrosion, while the "Si" silicon boost gives welders better puddle control — especially valuable for TIG welding where bead aesthetics and penetration control matter most.
