Post welding machine

Mainframe made of carbon steel painted, equipped with adjustable foots, safety panels and doors – all equipped with safety devices in according to CE standards.

Automatic regulation of height of head by recipe selectable on operator interface panel.

Automatic regulation  of wheelbase between two welding devices by recipe selectable on operator interface panel.

Handwheels for regulation of head on Y axle

Post welding head (**) has two welding devices (one for positive pole, the other for negative pole) equipped with supports oxyacetylene torches and welding shells.

Device for rotation of torches constituted with gears positioned eccentrically in refer to the axle of welding shells. It’s possible to adjust the eccentricity to direct the flame along the superior circumference of pole .

Pressure reducers for regulation of gas and oxygen

Asameters equipped with capacity regulation device

Electro-valves for opening/closing of gas and oxygen during the working cycle

Electro-valves for opening/closing of cooling water and flow rates for the control of water passage

Conveyor for battery transport equipped with synchronizer and stoppers.

Electrical cabinet with PLC Siemens S7-300, operator interface panel, push-button panel for manual commands.


Machine works car batteries only.

(*) In alternative we realize post welding machine that use dart technology: using the system of  heating of dart, this last enters for few millimetres in the bush of lid, allowing the welding between pin and bush.

 (**) It’s possible to increase to two operative heads to increase the productivity of machine
