Description
ESR 35 – Rutile-Basic Electrode (E6013 / E 38 2 RB 12) – MAGMAWELD
MAGMAWELD ESR 35 supports demanding welding work across the Norwegian industrial sector. The electrode combines rutile arc characteristics with the mechanical robustness of basic coatings. Therefore, welders choose it when they require stable arc behavior, predictable penetration and clean weld bead appearance. Moreover, because of its low silicon content, ESR 35 delivers weld metal that performs extremely well during galvanizing and enamelling. In practice, this property prevents surface defects and reduces post-weld corrections.
The electrode works reliably in workshops, shipyards and on-site fabrication tasks. It starts easily, and it restarts without sticking, which improves productivity. Furthermore, it maintains arc stability even when welders use compact inverter machines. As a result, ESR 35 suits both field operations and controlled workshop fabrication.
Welders typically select ESR 35 for:
root passes in pipe fabrication
boiler and pressure tank manufacturing
structural steel welding in all positions
repairs and maintenance on industrial steel structures
applications requiring clean weld surfaces for galvanizing
The main performance advantages include:
stable and smooth arc behavior
low spatter and very easy slag removal
consistent penetration and bead shape
weld metal toughness suitable for colder climates
compatibility with both AC and DC(−) sources
Since RAM SVEIS OG BEMANNING AS distributes ESR 35 exclusively in Norway, customers benefit from guaranteed authenticity and professional support.

Applications and Functional Characteristics
Because ESR 35 handles all welding positions, welders use it on pipes, tanks, flat plates and vertical structures. In addition, the electrode supports backing welds in submerged arc welding procedures. The combination of rutile and basic properties improves arc control, especially during vertical-up welding. Consequently, operators experience fewer defects, reduced re-work and more predictable weld quality.
Typical use cases include:
Pipe root passes in industrial installations
Tank and boiler fabrication
Structural steel fabrication and repair
Field welding where portability and reliability matter
Components that undergo galvanizing or enamelling
Typical Chemical Composition of Weld Metal
| C | Si | Mn |
|---|---|---|
| 0.08 | 0.20 | 0.50 |
This controlled chemistry ensures a clean weld metal that supports additional finishing processes.
Mechanical Properties
| Condition | Yield Strength (N/mm²) | Tensile Strength (N/mm²) | Elongation (%) | Charpy V-Notch (J) |
|---|---|---|---|---|
| As welded | 480 | 530 | 23 | 20°C: 100 J • 0°C: 60 J • −20°C: 50 J |
These values offer reliable toughness, and therefore suit applications exposed to low temperatures frequently encountered in Norway.
Welding Positions and Polarity
All welding positions: flat, horizontal, vertical-up, vertical-down, overhead
Polarity: AC or DC(−)
This versatility simplifies integration into workshop procedures and field operations.

The packaging protects the electrodes during transport, and it offers strong resistance to moisture. As a result, welders receive stable and ready-to-use electrodes.
Storage and Re-Drying Instructions
Most conditions do not require re-drying. However, if electrodes absorb moisture, heat them for 1 hour at 110°C. This process restores coating performance and maintains stable arc behavior.
