Stick Electrode Bohler Fox S EV50-1, AWS A5.1 E7018-1H4R
Stick Electrode
Process
For electric arc welding with stick electrodes, an electric arc is generated between the stick electrode and the base material. In shielded metal arc welding (SMAW) or manual metal arc welding (MMA) using coated stick electrodes, the coating forms a protective gas shield and a slag, thereby protecting the transferred metal droplets and the weld metal against contact with atmospheric oxygen.
Further functions of the coating are de-oxidation of the weld metal, increasing the metal recovery, compensating for burn-off and ensuring good wetting behaviour. In practical use there are three significant types of coating: rutile, basic and cellulosic and mixtures of these.
Coating types
According to the European Norm DIN EN ISO 2560, there are a total of eight different types of coated stick electrodes for arc welding of unalloyed steels and fine-grained steel. The four main types are named after their main components:
- C (Cellulose) cellulose electrodes
- A (Acid) acid electrodes*
- R (Rutile) rutile electrodes
- B (Basic) basic electrodes
*Acid electrodes can hardly be found anymore and have been almost completely replaced by rutile electrodes.
These coating types are a very important differentiator for the unalloyed stick electrodes. Stick electrodes for high strength, creep resistant or high-alloyed steels according to the other EN standards are mostly coated with rutile or basic coating elements.
Cellulose-coated stick electrodes
Due to the high level of cellulose in the coating, they have excellent properties for out-of-position welding, but poor properties for horizontal welding. They are therefore mainly used for vertical-down welding on large pipes.
Rutile-coated stick electrodes
These electrodes are very popular due to their good welding properties. The welding arc is stable and calm and is easy to reignite, the seams are finely rippled, and most of the slag comes off by itself. Rutile-coated electrodes have sufficient toughness properties, but are only suitable for out-of-position welding to a limited extent (high-alloy). BÖHLER electrodes for under water welding are a special type namely rutile acid (RA). They have a special sealing to protect against the water.
Basic-coated stick electrodes
The main advantages of basic electrodes are the outstanding toughness properties of the weld metal and its resistance to hot and cold cracks. Basic-coated electrodes have a coarse droplet material transfer, can be used to weld in all positions and have somewhat coarsely rippled seams. The slag can be relatively easily removed, but not as easily as with rutile-coated electrodes.
Stick electrode portfolio
Each type of steel needs a different stick electrode. It can be differentiated between the following steel types:
- Stick electrodes for unalloyed steels
- Stick electrodes for high-strength steels
- Stick electrodes for creep resistant steels
- Stick electrodes for stainless steels
- Stick electrodes for nickel and nickel alloys

Stick Electrode Bohler Fox S EV50-1, AWS A5.1 E7018-1H4R
Stick Electrode
A modern world would be unimaginable without electric arc welding – it is one of the oldest processes for joining metals and used all over the world. It is generally known as MMA (manual metal arc welding). Electric arc welding with stick electrodes is still indispensable in steel and pipeline construction and can be used under all weather conditions. Today, around 25 to 30% of the world’s welded products are produced with this process.Process
For electric arc welding with stick electrodes, an electric arc is generated between the stick electrode and the base material. In shielded metal arc welding (SMAW) or manual metal arc welding (MMA) using coated stick electrodes, the coating forms a protective gas shield and a slag, thereby protecting the transferred metal droplets and the weld metal against contact with atmospheric oxygen.
