The European Specifications for the Rutilen 13 SMAW Welding Rod
Rutilen 13 SMAW welding rods are long slender steel rods with flux coating used in shielded Metal Arc Welding Process, or SMAW. SMAW is a type of welding where the metals are melted and joined when an electric arc is heated. European specifications help to identify the quality and type of welding rod, the application of Rutilen 13 SMAW Welding Rod and the way it should be used to maximize performance.

Rod Flux Coating
-
Rod flux coating is a type of coating on the steel rod. European specifications state that Rutilen 13 welding rod should be coated with 25 to 45 percent titanium dioxide, or TiO2. It should also have arc stability to ionize and help positional rods to cool fast. In addition, the covered electrodes should not exceed 450 mm in length.
Application and Strength
-
Rutilen 13 SMAW electrodes should give up to 100 percent weld metal recovery, have a fine finish and provide moderate welding speed of about 140 grams per minute. Their strength is defined in terms yield strength (when the constituent metals begin to distort or bent) and tensile strength (when the metal begins to break). European specifications recommend that the electrodes be used for welding metals that have a nominal tensile strength that exceeds 440 Newton per square mm (45 kg per square mm).
-
Current Types
-
European specifications state that Rutilen 13 welding rod is applied for usage in any type of current. This is because it can operate using both alternating current (AC) and direct current (DC), depending on the electrode being used. It can also operate on transformers with low open circuit voltage, or OCV of a minimum of 42 volts. DC reverse polarity welding is, however, preferred over AC since it is flexible enough to be used in welding joins that are out of position and smooth arcs and since it is less sticking.
Positions
-
Rutilen 13 SMAW welding rods are high-efficiency electrodes suitable for welding in all positions, although when used in vertical positions, they prove to be most effective. When you use it to weld vertical or overhead positions, reduce the amperage of the welding machine from what you used on the horizontal position. Best results are realized once you maintain short arc, feed the electrode downward at a constant speed while it melts and move the welding rod at a uniform speed.
Amount of Amperage
-
Amount of amperage the welding machine can produce is crucial to the welding process. The European specifications state that the SMAW welding machine for Rutilen 13 electrode is within a range of 90 to 140 amperes.
