ESAB 36H Welding Electrode E7018

The ESAB 36H Welding Electrode is a basic-coated, hydrogen-controlled iron-powder electrode designed for professional MMA/SMAW welding applications. Classified as AWS A5.1 E7018, ESAB 36H is designed for welding mild and low-alloy steels where good weld quality, toughness and resistance to cracking are important.

The electrode is suitable for welding in all positions and is particularly useful for demanding fabrication work, heavy structures and applications where welding stresses cannot be avoided.

Low-Hydrogen Iron-Powder Coating

The ESAB 36H Welding Electrode uses a basic iron-powder coating with controlled diffusible hydrogen. ESAB specifies diffusible hydrogen of less than 5.0 ml/100 g, supporting applications where low-hydrogen welding consumables are required.

The coating also contributes to consistent welding performance and helps produce weld deposits with the mechanical properties required for structural and industrial applications.

E7018 Welding Electrode

The ESAB 36H Welding Electrode is classified to AWS A5.1 E7018 and EN ISO 2560-A E 42 3 B 32 H5. It is also listed under IS 814: EB5426H3JX.

This makes ESAB 36H a suitable consumable for welders working with mild steel and low-alloy steel where an E7018-class electrode is specified.

All-Position Welding

ESAB 36H is designed for welding in all positions, making it suitable for fabrication work where components cannot always be positioned conveniently for flat welding.

The electrode can be used with AC and DC+ welding current, with ESAB specifying a minimum AC open-circuit voltage of 70 V.

Tough and Crack-Resistant Welds

A major advantage of the ESAB 36H Welding Electrode is its ability to produce tough, crack-resistant weld metal on mild and low-alloy steels.

ESAB describes the electrode as suitable for restrained structures where welding stresses cannot be avoided. This makes it appropriate for demanding fabrication and structural applications where weld integrity is important.

X-Ray Quality Weld Deposits

ESAB 36H is designed to provide good radiographic-quality weld deposits. This characteristic makes it suitable for applications where weld quality and internal soundness are important considerations.

The electrode is therefore appropriate for professional fabrication operations and industrial welding applications where inspection and quality requirements are significant.

Welding Current and Electrode Sizes

The ESAB 36H Welding Electrode is available in several commonly used diameters. Current requirements vary according to electrode diameter.

Diameter	Length	ESAB Current Range
2.5 mm	350 mm	60–100 A
3.15 mm	450 mm	80–130 A
4.0 mm	450 mm	100–190 A
5.0 mm	450 mm	180–260 A

These ranges are the current values published on ESAB India’s product page.

Why Choose ESAB 36H Welding Electrode?

The ESAB 36H Welding Electrode is a strong choice when an E7018-class low-hydrogen consumable is required for mild and low-alloy steel welding. Its basic coating, iron-powder formulation and controlled hydrogen characteristics are designed for demanding welding applications.

Its all-position capability also makes the electrode practical for fabrication environments where welds are performed in different positions. Combined with its tough and crack-resistant weld characteristics, ESAB 36H is suited to professional fabrication, structural welding and industrial maintenance.

For applications involving boilers, pressure vessels, heavy structures or other critical components, always confirm that the electrode classification, approvals, diameter and welding procedure meet the project’s applicable specifications.

Welding Safety

Always follow the welding machine manufacturer’s operating instructions and the electrode manufacturer’s recommended storage, handling and welding procedures. Use appropriate welding PPE, including a suitable welding helmet, gloves, protective clothing and safety footwear.

Low-hydrogen electrodes should also be stored and handled according to the applicable welding procedure and manufacturer’s instructions to maintain consumable performance.
