    Exothermic welding is a self contained fusion welding process that allows very high quality electrical connections between copper, copper alloy or steel conductors. The process involves the use of a graphite mold which allows the molten metal inside to come into contact with the conductors present and to weld them permanently. Molds are manufactured in our workshops from a block of graphite according to the weld configuration required.

    The size of the mold is defined according to the number of welds to be made and the nature and dimensions of the conductors to be welded:

    1. The C size molds can make up to 50 welds
    2. The B size molds can make up to 30 welds

    Our BB47 mold type model is designed to weld tape conductor crowsfoot weld shape.

    How to choose all the required exothermic welding materials ?

    To choose all of the required materials, follow the steps below:

    1. Select the graphite mold
    2. Select the handle clamp
    3. Select the metal powder
    4. Select the ignition method
    5. Select the accessories and safety equipments

    What if the welding configuration is not available on MALTEP website ?

    MALTEP also manufactures graphite molds for the realization of particular welding configuration.

    Do not hesitate to consult us for any particular request with the following welding inputs:

    • The configuration  of the weld: tee, parallel, etc..
    • The nature of the conductors to be welded: cable, round, rebar, etc. (note that aluminium is not suitable with exothermic welding)
    • The cross section, diameter, conductors dimensions
    • The number of welds to be done for each type of weld
