The Bonarc 7018 3.2mm Stick Electrode is a high-performance consumable designed for the Shielded Metal Arc Welding (SMAW) process. Engineered for professional industrial applications, this electrode features a low hydrogen, iron powder coating that delivers exceptional weld quality on mild and low-alloy steels. It is the go-to choice for fabricators requiring X-ray quality welds with superior mechanical properties, particularly in structural applications where joint integrity is critical.<\/p>\n
One of the standout features of the Bonarc 7018 is its excellent operator appeal. The electrode strikes and re-strikes easily, maintaining a stable arc that is easy to control in all positions. The addition of iron powder to the coating not only improves the deposition rate but also assists in producing a smooth, uniform bead profile with minimal spatter. Slag removal is often self-releasing or requires minimal chipping, which significantly improves productivity during multi-pass welding operations.<\/p>\n
This electrode is classified as E7018 by the American Welding Society (AWS), indicating a minimum tensile strength of 70,000 psi. It is specifically formulated to resist moisture absorption, although proper storage in a rod oven is recommended to maintain its low hydrogen status. The Bonarc 7018 is versatile enough to be used with both DC+ (Reverse Polarity) and AC power sources, making it compatible with a wide range of welding machines found in workshops and field sites.<\/p>\n
For industries ranging from construction to shipbuilding, the Bonarc 7018 provides the reliability needed for critical joints. Its ability to produce crack-resistant welds on difficult-to-weld steels makes it an essential inventory item for maintenance and repair operations (MRO). Whether you are welding heavy I-beams, pressure vessels, or machinery frames, this 3.2mm electrode offers the penetration and strength required for heavy-duty tasks.<\/p>\n","protected":false},"excerpt":{"rendered":"Use for structural steels for building, bridge construction, storage tank fabrication, ship building and machinery fabrication.","protected":false},"featured_media":0,"template":"","meta":{"_acf_changed":false},"product_brand":[],"product_cat":[1961,1959],"product_tag":[],"class_list":{"0":"post-1783915","1":"product","2":"type-product","3":"status-publish","5":"product_cat-steel-electrodes","6":"product_cat-welding-wires-and-electrodes","7":"pa_amp-range-100-160amp","8":"pa_amp-range-110-150amp","9":"pa_aws-spec-e7018","10":"pa_brand-bonarc","11":"pa_diameter-3-2mm","12":"pa_packaging-description-4-5kg-tube","13":"pa_polarity-ac-dc","14":"pa_polarity-dc-ac","15":"pa_position-all","17":"first","18":"instock","19":"taxable","20":"shipping-taxable","21":"purchasable","22":"product-type-simple"},"acf":[],"_links":{"self":[{"href":"https:\/\/josefgases.com\/stage\/wp-json\/wp\/v2\/product\/1783915","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=1783915"}],"wp:term":[{"taxonomy":"product_brand","embeddable":true,"href":"https:\/\/josefgases.com\/stage\/wp-json\/wp\/v2\/product_brand?post=1783915"},{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/josefgases.com\/stage\/wp-json\/wp\/v2\/product_cat?post=1783915"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/josefgases.com\/stage\/wp-json\/wp\/v2\/product_tag?post=1783915"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
