The Lincoln Electric SuperArc\u00ae LA-90 is a top-tier choice for industrial welding applications requiring superior tensile strength and reliability. Classified as both ER80S-D2 and ER90S-D2 under AWS A5.28 standards, this .035-inch solid wire is engineered for the welding of high-strength low-alloy (HSLA) steels. It is particularly effective in applications where high yield strength and impact toughness are critical, such as in heavy equipment manufacturing, structural fabrication, and pressure vessel construction.<\/p>\n
One of the standout features of the SuperArc\u00ae LA-90 is its specific chemical composition, which includes approximately 0.50% molybdenum. This addition significantly enhances the mechanical properties of the weld deposit, maintaining strength even after stress-relief heat treatments. The wire is capable of producing weld deposits with tensile strengths ranging from 80,000 to 90,000 psi (552-620 MPa), ensuring that your welds meet rigorous industrial standards.<\/p>\n
Lincoln Electric has treated this wire with their proprietary Microguard\u00ae Ultra surface finish. This premium copper coating is designed to eliminate common feeding issues associated with standard wires. It reduces friction within the liner and contact tip, promoting smooth, uninterrupted feeding and stable arc characteristics. Whether you are utilizing short-circuiting, globular, axial spray, or pulsed spray transfer modes, the SuperArc\u00ae LA-90 delivers consistent performance and high-quality bead appearance.<\/p>\n
Packaged in a substantial 44 lb spool, this product is optimized for high-volume production environments where minimizing changeover time is essential. By choosing Lincoln SuperArc\u00ae LA-90 from Josef Gas, you are investing in a consumable that balances operational efficiency with metallurgical excellence.<\/p>\n","protected":false},"excerpt":{"rendered":"Lincoln\u00ae Superarc\u00ae LA-90 is capable of producing weld deposits with 550 – 620 Mpa tensile strength.\n\nContains 0.50% molybdenum for strength after stress-relief.\n\nMicroguad\u00ae Ultra provides superior feeding and arc stability.\n\nSupports short-circuiting, globular, axial spray and pulsed spray transfer.","protected":false},"featured_media":0,"template":"","meta":{"_acf_changed":false},"product_brand":[],"product_cat":[1967,1959],"product_tag":[],"class_list":{"0":"post-1752598","1":"product","2":"type-product","3":"status-publish","5":"product_cat-specialty-electrodes-wires","6":"product_cat-welding-wires-and-electrodes","7":"pa_brand-lincoln","8":"pa_diameter-0-035-2","9":"pa_diameter-0-035","10":"pa_grade-na","11":"pa_grade-steel","12":"pa_packaging-44lb-spool-2","13":"pa_packaging-n-a","14":"pa_packaging-description-44lb-spool","15":"pa_packaging-description-44lb-spool-3","16":"pa_polarity-dc-2","17":"pa_polarity-na","18":"pa_position-all-position-2","19":"pa_position-n-a","20":"pa_weld-process-mig","22":"first","23":"onbackorder","24":"taxable","25":"shipping-taxable","26":"purchasable","27":"product-type-simple"},"acf":[],"_links":{"self":[{"href":"https:\/\/josefgases.com\/stage\/wp-json\/wp\/v2\/product\/1752598","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/josefgases.com\/stage\/wp-json\/wp\/v2\/product"}],"about":[{"href":"https:\/\/josefgases.com\/stage\/wp-json\/wp\/v2\/types\/product"}],"wp:attachment":[{"href":"https:\/\/josefgases.com\/stage\/wp-json\/wp\/v2\/media?parent=1752598"}],"wp:term":[{"taxonomy":"product_brand","embeddable":true,"href":"https:\/\/josefgases.com\/stage\/wp-json\/wp\/v2\/product_brand?post=1752598"},{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/josefgases.com\/stage\/wp-json\/wp\/v2\/product_cat?post=1752598"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/josefgases.com\/stage\/wp-json\/wp\/v2\/product_tag?post=1752598"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
