The Hobart Hoballoy 10018-D2 is a premium low-hydrogen, iron powder electrode designed specifically for the Shielded Metal Arc Welding (SMAW) of high-tensile steels. Classified under AWS A5.5 as E10018-D2, this electrode is formulated with a Manganese-Molybdenum (Mn-Mo) alloy system. This chemical composition is critical for achieving a minimum tensile strength of 100,000 psi (690 MPa) in the as-welded condition, making it suitable for joining high-strength low-alloy (HSLA) steels such as ASTM A514 and A517.<\/p>\n
Metallurgically, the Hoballoy 10018-D2 offers a fine-grained weld deposit that exhibits excellent ductility and impact toughness, even at sub-zero temperatures. The coating is engineered to resist moisture absorption, a vital characteristic for preventing hydrogen-induced cracking (cold cracking) in the heat-affected zone (HAZ) of hardenable steels. It typically meets H4 diffusible hydrogen designations, ensuring less than 4ml of hydrogen per 100g of deposited weld metal when stored and handled correctly.<\/p>\n
This 5\/32-inch (4.0 mm) diameter variant operates optimally on Direct Current Electrode Positive (DCEP). The iron powder content in the coating increases deposition rates compared to non-iron powder equivalents, improving travel speeds and overall productivity. The slag system is designed for easy removal, revealing a smooth bead profile with minimal spatter. It is an all-position electrode, capable of producing X-ray quality welds in flat, horizontal, vertical-up, and overhead positions.<\/p>\n
Storage and Handling:<\/strong> As a low-hydrogen consumable, Hoballoy 10018-D2 must be stored in a dry environment. Once the hermetically sealed 50 lb can is opened, electrodes should be maintained in a rod oven at temperatures between 250\u00b0F and 300\u00b0F (120\u00b0C – 150\u00b0C) to preserve their low-hydrogen status. Reconditioning of exposed electrodes should follow manufacturer guidelines, typically requiring baking at higher temperatures.<\/p>\n","protected":false},"excerpt":{"rendered":"Technical Analysis: Hobart Hoballoy 10018-D2 The Hobart Hoballoy 10018-D2 is a premium low-hydrogen, iron powder electrode designed specifically for the Shielded Metal Arc Welding (SMAW) of high-tensile steels.
