Abstract

An electric resistance welding machine includes a machine body unit constructed in a structure in which with a footstool is formed at the lower part of a machine body, at the middle of which a welding table, at which welding is carried out, is installed, and transfer wheels to transfer the machine body are formed below the footstool, a welding fixing unit constructed in a structure in which a welding support member having a pressurization shaft fixing part is formed on a welding base, formed at the middle of the welding table of the machine body unit, and a power connection part for power connection is formed at one side of the welding support member, a pressurization unit constructed in a structure in which a pressurization body, supported by a pressurization shaft fixed by the pressurization shaft fixing part, is formed above the welding fixing unit, a pressurization cylinder is formed at one side of the pressurization body, a pressurization fixing member, which is movable by the operation of the pressurization cylinder, is formed below the pressurization body, and a pressurization power supply part for power supply is formed at one side of the pressurization fixing member, a jig unit constructed in a structure in which the welding support member of the welding fixing unit is provided at the front thereof with a stationary jig fixing member, to which the stationary jig is fastened by a stationary jig fastening member, power being supplied to the stationary jig fixing member, and a pressurization jig fixing member, to which the pressurization jig is fastened by a pressurization jig fastening member, is formed at one side of the pressurization fixing member upstream of the coupling position between the stationary jig and the pressurization jig, and a control unit constructed in a structure in which, at one side of the machine body unit, power is supplied to the power connection part of the welding fixing unit, and the power is also supplied to the pressurization power supply part of the jig unit, whereby the power is supplied to parts in contact by the pressurization, and therefore, the contact parts are joined to each other by contact heat. The pressurization unit is constructed in a structure in which a pressurization block, which is pressurized by the operation of the pressurization cylinder, is coupled to the pressurization fixing member inside the pressurization body, whereby the pressurization block is pressurized by the operation of the pressurization cylinder, while power is supplied to the pressurization unit, and therefore, the pressurization jig is successively pressurized, with the result that the contact parts are joined to each other, while being pressurized, by joining heat generated by electric resistance at the contact parts.
