Twin Carbon Arc Welding in Action

Let’s take a closer look at the step-by-step process of executing Twin Carbon Arc Welding:

  • Preparation: Thoroughly clean and prepare the surfaces to be welded, ensuring the removal of any contaminants or impurities.
  • Electrode Placement: Position the two carbon electrodes at the desired welding location, maintaining an appropriate distance.
  • Arc Initiation: Create an electric arc between the electrodes, generating intense heat that melts the metal surfaces.
  • Weld Pool Formation: As the metal surfaces liquefy, a weld pool is formed, ready for the fusion process.
  • Fusion: Control the movement of the electrodes to guide the weld pool’s solidification and fusion, creating a seamless joint.
  • Cooling and Solidification: Allow the molten metal to cool and solidify, forming a robust weld joint with exceptional strength.

Disadvantages of Twin Carbon Arc Welding
