XHD 2222 Welding Electrodes

At Metals And Welding Specialities, we proudly present the XHD 2222 Welding Electrodes, engineered for demanding welding and repair tasks across heavy industry. Our XHD 2222 electrode offers an ideal solution when you require a high-strength, corrosion-resistant weld metal that performs under thermal cycling and stress. When selecting electrodes for critical repair or joining, the XHD 2222 stands out for its versatility, toughness, and metallurgical stability.

The XHD 2222 electrode (commonly known under the universal designation “E Ni-1” per DIN EN standards) is a nickel-based rutile-basic coated stick electrode. Its weld deposit is rich in Ni-Cr-Fe-Mn alloying elements, delivering superior resistance to oxidation, scaling, and stress‐induced cracking. Typical tensile strength reaches 90,000 psi (≈ 630 MPa) and yield strength is about 65,000 psi (≈ 450 MPa), while elongation stays in the 30–35 % range even in heavy section welds.

In service, XHD 2222 excels in joining carbon steels, heat-treatable steels, cryogenic steels, nickel alloys, and dissimilar combinations thereof. Its deposit shows minimal residual stress and reduced susceptibility to embrittlement from sigma phases, carbides or nitrides. The electrode performs reliably under both AC and DC+ current modes, with typical amperage ranges of 80–160 A depending on diameter (e.g. 2.5–4.0 mm)

Although XHD 2222 does not map directly to a single ASTM “Grade” (since it is a high-nickel alloy electrode rather than a carbon steel welding consumable), it is often referenced in specifications as E Ni-1 (or sometimes under custom nickel‐based filler classifications). For clarity and purchasing specifications, its UNS (Unified Numbering System) designation is UNS N02201 (a typical Ni–Cr–Fe weld alloy in this class). In practice, when specifying in drawings or procurement documents, many users will call it “ASTM E Ni-1 / UNS N02201 – XHD 2222 Coated Electrode.”

Metals And Welding Specialities ensures that every batch of XHD 2222 Welding Electrodes is rigorously quality tested for coating integrity, moisture content, and weld metal chemistry. We recommend preheating only when required by the base metal (particularly when joining crack‐sensitive steels or very thick sections), controlling heat input, and employing short arc technique with stringer beads to manage distortion. Interpass cleaning and light peening may further enhance crack resistance and deposit integrity.

Clients deploying XHD 2222 typically include heavy equipment repair shops, furnace maintenance teams, kiln shell repair specialists, and petrochemical plant welders. It is frequently used for flame-hardening equipment, heat-treating racks & trays, kiln tyre repairs, ingot tongs, continuous casting molds, cryogenic service parts, and dissimilar metal joints requiring high corrosion resistance .
