The Esab Spoolarc 83 is a premium copper-coated solid MIG welding wire designed for joining high-strength low-alloy (HSLA) steels. Classified as ER90S-D2 under AWS A5.28 standards, this wire is engineered with a specific chemical composition containing approximately 0.50% Molybdenum. This alloying element significantly enhances the mechanical properties of the weld deposit, providing high tensile strength (typically exceeding 90,000 psi) and maintaining ductility even in demanding service conditions. It is the ideal choice for fabricators working with materials such as ASTM A514, A517, and other high-yield strength steels commonly found in heavy industrial sectors.<\/p>\n
Beyond its strength, Spoolarc 83 is formulated with high levels of Manganese and Silicon. These deoxidizers act as powerful cleaning agents during the welding process, scavenging impurities and allowing the wire to perform exceptionally well on base metals that may have light rust, mill scale, or oil. This makes it a versatile consumable for both manufacturing environments and field repairs where surface preparation cannot always be perfect. The 20kg spool size ensures long run times for automated or semi-automated setups, reducing downtime associated with changeovers.<\/p>\n
This wire exhibits excellent wetting characteristics, resulting in a flat bead profile and smooth tie-ins, which reduces the need for post-weld grinding. It is suitable for use with both 100% CO2 and Argon\/CO2 shielding gas mixtures, offering flexibility depending on the desired arc characteristics and penetration profile. Whether used for single-pass fillets or complex multi-pass groove welds, Spoolarc 83 delivers consistent, X-ray quality results.<\/p>\n","protected":false},"excerpt":{"rendered":"Spoolarc 83 contains 0.5% MO to provide higher deposit strength in both the as welded and stress relieved conditions.","protected":false},"featured_media":0,"template":"","meta":{"_acf_changed":false},"product_brand":[],"product_cat":[1962,1959],"product_tag":[],"class_list":["post-1750719","product","type-product","status-publish","product_cat-steel-mig-and-tig-wires","product_cat-welding-wires-and-electrodes","pa_aws-spec-er80s-d2","pa_aws-spec-er90s-d2","pa_brand-esab","pa_diameter-0-045","pa_grade-er80s-d2","pa_packaging-20kg-spool","pa_packaging-44lb-spool","pa_packaging-description-20-kg-spool","pa_polarity-dc","pa_weld-process-mig","pa_wire-type-solid","first","onbackorder","taxable","shipping-taxable","purchasable","product-type-simple"],"acf":[],"yoast_head":"\n
