61802400 - Bonarc E6011 3/32" Stick Welding Rods

Technical Overview of Bonarc E6011 Electrodes

The Bonarc E6011 is a high-quality mild steel stick electrode designed to meet AWS A5.1 specifications. Classified as E6011, this electrode features a high-cellulose potassium coating that enables it to operate effectively on Alternating Current (AC) as well as Direct Current Electrode Positive (DCEP). The chemical composition of the coating generates a forceful, digging arc that ensures deep penetration into the base metal, making it suitable for root passes in pipe welding and structural fabrication where full fusion is critical.

One of the defining characteristics of the Bonarc E6011 is its fast-freezing slag system. This property allows for excellent control of the weld puddle in out-of-position welding, specifically vertical-up, vertical-down, and overhead positions. The rapid solidification of the molten pool helps prevent sagging and undercut, providing a distinct ripple pattern characteristic of cellulosic electrodes. The 2.5mm (approximately 3/32 inch) diameter is particularly versatile, offering a balance between deposition rate and heat input, suitable for thinner gauge materials or bridging gaps in poor fit-up scenarios.

Metallurgically, the deposited weld metal exhibits tensile strengths exceeding 60,000 psi, ensuring structural integrity for mild steel applications. The electrode is engineered to tolerate moderate levels of surface contamination, reducing the need for extensive pre-weld cleaning. It is an essential consumable for industrial maintenance, repair operations (MRO), and field fabrication where environmental conditions and base metal preparation may be less than ideal.
