To determine

The items that make up a basic semi-automatic welding system.

Answer to Problem 1R

The equipments of semi-automatic GMA welding are power source, shielding gas supply, switch circuit, welding gun, conduit, electrode feeder, Electrode supply, power cables, shielding gas regular and shielding gas hose.

Explanation of Solution

The basic semi-automatic GMA welding installation consist the elements which are listed below:

  • Power source:

    A power source is required to maintain the equipment to work without any interruptions and indulgence of welder.

  • Shielding gas supply:

    Shielding gas supply is must to prevent the weld from oxidation.

  • Shielding gas flow meter regulator:

    For a semi-automatic welding machine the flow meter should be required to adjust the amount of shielding gas required for the weld.

  • Shielding gas hose:

    It is a basic component required to transfer the shielding gas form the cylinder to the welding gun.

  • Switch circuit:

    It is a circuit that contains the control of current, voltage and the travel speed of the electrode gun.

  • Welding gun:

    The welding gun is the basic component required to hold the electrode in a position during the welding process.

  • Conduit and welding control:

    Conduit is required to protect the electrode from the damage and deformation through the feeding of electrode from feeder to Gun.

  • Electrode feeding unit:

    Electrode should be fed with an uniform rate for better weld quality thus, an electrode feeder is required to provide the electrode by a constant rate to the weld.

  • Power cables and work cables:

    Power cables are required for the power supply to the machine as the current flowing through the electrode is of high amperage it requires a high current wire cables which can sustain the current of high magnitude.

Conclusion:

Thus, the equipments of semi-automatic GMA welding are power source, shielding gas supply, switch circuit, welding gun, conduit, electrode feeder, Electrode supply, power cables, shielding gas regular and shielding gas hose.
