ESAB 36H SPL E7018-1 Low Hydrogen Electrode Dubai UAE
ESAB 36H SPL Low Hydrogen Welding Electrode
Basic-coated, low hydrogen electrode for critical structural, pipeline, and pressure vessel welding. E7018-1 classification confirms diffusible hydrogen <5 ml/100g — essential for hydrogen crack-free welds on high-strength and heavy-section steels across the Middle East and Africa.
Product Overview
⚠️ Why Low Hydrogen Electrodes Are Mandatory on Critical Welds
Basic-coated low hydrogen electrodes like the E7018-1 are specified by welding procedures on structural, pipeline, and pressure vessel work because they keep diffusible hydrogen in the weld metal below 5 ml per 100g. Moisture-contaminated electrodes cause hydrogen-induced cracking (HIC) — particularly dangerous on high-strength steels, thick sections, and highly restrained joints. Electrodes must be stored in a welding oven at 70°C–150°C and used within procedure-specified timeframes. On ADNOC, Aramco, QatarEnergy, and international oil & gas projects, the use of low hydrogen electrodes is a mandatory WPS requirement.
What It Is
The ESAB 36H SPL is a basic-coated, low hydrogen SMAW (stick) electrode classified AWS E7018-1. The "1" suffix indicates enhanced toughness at low temperatures — 27 J at -46°C versus -29°C for standard E7018. It provides high weld metal strength, superior crack resistance, and excellent mechanical properties for critical welding applications on carbon and low-alloy steels.
Who Uses It
Specified by welding engineers and QC inspectors on structural, pipeline, offshore, and pressure vessel projects. Mandatory on welded joints subject to PWHT, radiographic or ultrasonic testing. Used by welding contractors across UAE (ADNOC), Saudi Arabia (Aramco, SABIC), Qatar (QatarEnergy), Iraq (pipeline projects), Kuwait, Nigeria (NNPCL), Kenya, and South Africa where WPS requires E7018 or E7018-1 classification.
Where It Is Used
Structural steel fabrication and erection, oil & gas pipeline construction and tie-ins, pressure vessel and heat exchanger fabrication, offshore platform structural welding, heavy machinery and crane manufacture, shipbuilding and marine structural welding, and any application where a welding procedure specification requires an E7018-1 low hydrogen electrode with all-position capability.

Key Features & Benefits
Low Hydrogen — <5 ml/100g
E7018-1 classification guarantees diffusible hydrogen below 5 ml per 100g — the critical threshold for preventing hydrogen-induced cracking in structural, pipeline, and pressure vessel welds on carbon and low-alloy steels. Essential on WPS-qualified welding procedures specifying hydrogen control.
Enhanced Low-Temperature Toughness
The "-1" designation confirms Charpy V-Notch impact toughness of 27 J at -46°C — significantly better than standard E7018 which requires the same at -29°C. Critical for welds in low-temperature service environments, offshore structures, LNG facilities, and cold-climate pipeline projects.
High Strength & Crack Resistance
Minimum 480 MPa tensile strength and 400 MPa yield strength meet the requirements of most structural and pipeline WPS. Superior crack resistance from the basic coating chemistry makes it the mandatory choice for high-restraint joints, heavy sections, and high-strength steel fabrication.
All-Position Capability
Excellent performance in all welding positions — flat, horizontal, vertical-up, and overhead. Well-suited for site welding conditions encountered on construction projects and pipeline work across the Gulf and Africa where restricted access and difficult welding positions are common.
AC / DC+ Versatility
Operates on AC (70V OCV minimum) or DC+ power sources — compatible with the majority of welding machines available on construction sites across the UAE, Saudi Arabia, Iraq, Nigeria, and Kenya. DC+ is preferred for optimum arc stability and penetration.
Code Compliance — Structural & Pressure Vessel
AWS E7018-1 classification satisfies the electrode requirements of AWS D1.1 (Structural Welding Code), ASME Section IX, and API 1104 (pipeline welding) welding procedures specifying low hydrogen E7018 or E7018-1 electrodes — accepted by inspection authorities across ADNOC, Aramco, QatarEnergy, and NNPCL projects.
Applications by Industry
| Industry | Application |
|---|---|
| Structural Steel | Column and beam connections, bracing, heavy plate fabrication, and structural welding on buildings, bridges, and industrial structures requiring AWS D1.1 E7018-1 electrode compliance across UAE, Saudi Arabia, Egypt, Kenya, and South Africa |
| Oil & Gas — Pipeline | Pipeline tie-in welding, fitting and valve welding, and mainline repair welding where API 1104 or company welding procedures specify E7018-1 low hydrogen electrode — ADNOC (UAE), Aramco (Saudi Arabia), QatarEnergy (Qatar), SOC (Iraq), NNPCL (Nigeria) |
| Pressure Vessels | Shell and nozzle welding on ASME Section VIII pressure vessels, heat exchangers, and process vessels where ASME Section IX WPS requires E7018-1 classification in the petrochemical and oil & gas sector |
| Offshore Structures | Jacket, topside, and module structural welding on offshore platforms in the Arabian Gulf, offshore Nigeria, and offshore Oman — where DNV, Lloyd's, or ABS class requirements specify low hydrogen electrode compliance |
| Heavy Machinery | Crane booms, earthmoving equipment, mining machinery, and heavy fabrications using high-strength steels requiring controlled hydrogen welding to avoid HIC — South Africa, Ghana, Nigeria, Kenya |
| Shipbuilding | Hull structural welding, deck plate welding, and structural connection welding in UAE (Dubai Drydocks), South Africa (Cape Town), and Nigeria (Lagos) shipyards where classification society rules mandate low hydrogen electrodes |
