Here it indicates that the weld must be annealed to between to deg C for one hour then cooled in furnace to deg C and thereafter cooled in air. Minimum Impact Temperature at 46J This represents the temperature at which the weld material becomes brittle. There is an additional field included here for some specialist rods and represents the percentage of Manganese MnNickel Ni and Molybdenum Mo in the filler metal. Please refer the table below for other symbols. Please refer the table below for other key numbers and the associated welding positions. These suffixes generally differ from manufacturer to manufacturer and even though the electrodes may be belonging to the same standard they may still be slightly different as each manufacturer likes to add a personal touch.

  • Welding is the process of joining materials together by melting the two pieces and adding a third melted material. Electrodes provide a current.

    AWS A/AM is the Specification for Carbon Steel Electrodes for Shielded E E = Electrode, The first two digits = tensile strength minimum in ksi of the. MMA Electrode Classification. Some rods perform best when used downhand. Some also perform well out of position ie vertical upwards, overhead, vertical.

    In this case it is basic coating containing Calcium Carbonate. This page decodes the classification used for the more common rod types. Here it indicates that the weld must be annealed to between to deg C for one hour then cooled in furnace to deg C and thereafter cooled in air.

    Otherwise these alloyed grades are normally used for welding mild steel that has been "improved" for applications such as offshore work. As it is more than the amount of metal present in the welding electrode it means that the flux coating has some iron powder.

    Please refer the table below for the other type of flux coatings. Please refer the table below for other key numbers and the associated welding positions. For fillet welds they can also be used in horizontal and vertical positions.

    Please refer the table below for other key numbers and their properties. Please refer the table below for other suffixes. These suffixes generally differ from manufacturer to manufacturer and even though the electrodes may be belonging to the same standard they may still be slightly different as each manufacturer likes to add a personal touch.

    Please refer to the chart below for the other key numbers and the associated tensile strength. From the last 2 digits:.

    Thus the number E written on an electrode indicates that it is a rutile potassium based flux coated mild steel electrode with 62, psi minimum tensile strength having light penetration which can be used in all positions of welding except vertically down.

    Otherwise these alloyed grades are normally used for welding mild steel that has been "improved" for applications such as offshore work. But it doesn't roll off the tongue quite so easily as the AWS classification. The ISO standard gives you more information especially the last two digits signifying the operation characteristics.

    Thanks very much and keep publishing…. In this case it is basic coating containing Calcium Carbonate. Here it means all positions except vertically down.

    The following classification changes will be effected by this Notice of Changes: Action*. Subclass Y10T29/ 4 . Electrode. N.

    Thanks very much and keep publishing…. He has 12 years of experience as Marine Engineer. Rutile Basic Another hybrid. In this article we shall discuss the nomenclature and classification of the electrodes based on popular ISO and AWS standards.

    MMA Electrode Classification

    Yield Strength is where the metal starts to deform plastically when it doesn't spring back to it's original form after the load is released.

    They are normally used for Low Hydrogen rods.

    E 60 XX: The next two characters indicate the minimum tensile strength.

    In other words the coating contains iron powder or in some rods other alloys. Otherwise these alloyed grades are normally used for welding mild steel that has been "improved" for applications such as offshore work.

    Rutile E In welding rod coatings it provides slag cover, arc stability it ionizes easily and helps the fast freeze ability of positional rods.
