  • Page 27: Mma Welding

    INSTALLATION & OPERATION §3.3.3 MMA Welding One of the most common types of arc welding is manual metal arc welding (MMA) or stick welding. An electric current is used to strike an arc between the base material and a consumable electrode rod or ‘stick’. The electrode rod is made of a material that is compatible with the base material being welded and is covered with a flux that gives off gaseous vapours that serve as a shielding gas and providing a layer of slag, both of which protect the weld area from atmospheric contamination.

  • Page 28: Mma Welding Fundamentals

    INSTALLATION & OPERATION The Metal Wire Core works as conductor of the current that maintains the arc. The core wire melts and is deposited into the welding pool. The covering on a shielded metal arc welding electrode is called Flux. The flux on the electrode performs many different functions.

With the current set too low, difficulty is experienced in striking and maintaining astable arc.

    INSTALLATION & OPERATION be connected to (this rule applies to all the other forms of DC welding as well). DC TIG welding is a process in which an arc is struck between a TUNGSTEN electrode and the metal work piece. The weld area is shielded by an inert gas flow to prevent contamination of the tungsten, molten pool and weld area.

However, some welds combining thin materials can be accomplished without filler metal like edge, corner, and butt joints. This is known as Fusion welding where the edges of the metal pieces are melted together using only the heat and arc force generated by the TIG arc.

  • Page 34: Tungsten Electrodes

    INSTALLATION & OPERATION §3.4.4 Tungsten Electrodes Tungsten is a rare metallic element used for manufacturing TIG welding electrodes. The TIG process relies on tungsten’s hardness and high-temperature resistance to carry the welding current to the arc. Tungsten has the highest melting point of any metal, 3,410 degrees Celsius.
  • Page 35 INSTALLATION & OPERATION E3 tungsten electrodes (AWS classification EWG) contain a minimum of 98% percent tungsten and up to 1.5 percent Lanthanum and small percentages of Zirconium and Yttrium they are called E3 Tungsten. E3 Tungsten Electrodes provide conductivity similar to that of thoriated electrodes.

    INSTALLATION & OPERATION use with AC sine wave power sources. Lanthanated tungsten maintains a sharpened point well, which is an advantage for welding steel and stainless steel on DC or AC from square wave power sources. Zirconiated (Color Code: White) Zirconiated tungsten electrodes (AWS classification EWZr-1) contain a minimum of 99.10 percent tungsten and 0.15 to 0.40 percent zirconium.
  • Page 37 INSTALLATION & OPERATION Electrode Tip/Flat The shape of the tungsten electrode tip is an important process variable in precision arc welding. A good selection of tip/flat size will balance the need for several advantages. The bigger the flat, the more likely arc wander will occur and the more difficult it will be to arc start.
