ER80S-D2 / ER100S-G robotic welding plagued by bird-nesting, spatter, and downtime? Learn how poor cast and helix tolerance cause feeding failures
High-Strength Solid Wire Low-Temperature Impact Toughness Solution" meta_description: "Why ER100S-G passes tensile but fails -40°C Charpy. Learn how Ti-B micro-alloy control ensures stable low-tempera
High-strength wires (ER80S-G etc.) look fine post-weld, but cracks appear hours later due to martensite + hydrogen + stress in thick parts. GD-WELD controls impurities to cut crack risk.
Compare the four common arc welding processes—MIG, TIG, Stick, and flux-core—so you can pick the right method for steel, aluminum, outdoor repair, or precision work.
Install flux-core welding wire for gasless MIG the right way: spool direction, drive-roll tension, stickout, and DCEN polarity to stop bird-nesting and porous welds.

E2594-16 is a super duplex stainless steel welding electrode for SMAW applications on 2507-type materials. It provides high-strength weld metal with excellent resistance to pitting, crevice corrosion and stress corrosion cracking. It is commonly used for UNS S32750, UNS S32760 and similar super duplex stainless steels in offshore, oil & gas, seawater, chemical and pressure equipment applications.
E2209-16 is a rutile-coated duplex stainless steel welding electrode classified to AWS A5.4 / ASME SFA-5.4 E2209-16. It produces ferritic-austenitic weld metal with high strength and good resistance to pitting, intergranular and stress corrosion. It is primarily used for Duplex 2205, UNS S31803, UNS S32205 and SAF 2205 in oil and gas, offshore, chemical processing, piping and marine applications.
E320-16 is a high-alloy austenitic stainless steel welding electrode for severe corrosion-resistant applications. It is classified under AWS A5.4 E320-16 and GB/T 983 E320-16, and is commonly supplied as A902 E320-16. With a Cr-Ni-Mo-Cu-Nb weld metal, E320-16 is mainly used for Carpenter 20Cb, Alloy 20, and similar corrosion-resistant alloys, particularly in chemical processing and sulfuric acid service.
