STICK WELDING ELECTRODE

Electric arc welding (using welding electrode) – 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 welding electrode 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.
In arc welding, an electrode is used to conduct current through a workpiece to fuse two pieces together. Depending upon the process, the electrode is either consumable, in the case of gas metal arc welding or shielded metal arc welding, or non-consumable, such as in gas tungsten arc welding. For a direct current system, the weld rod or stick may be a cathode for a filling type weld or an anode for other welding processes. For an alternating current arc welder, the welding electrode would not be considered an anode or cathode.
Electric arc welding with stick welding electrodes is one of the oldest and most versatile welding processes. And it is also considered as one of the simplest and safest methods. It is used to weld almost all types of metals. Stick electrodes are even used for underwater welding.
Process
For electric arc welding with stick welding 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 behavior. In practical use there are three significant types of coating: rutile, basic and cellulosic and mixtures of these.

Welding Electrodes
Most used welding electrodes are : welding electrode 6013 & 7018, Each type of steel needs a different welding 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
