Mandrels and Centering Cartridges<\/span><\/h1>\n

They have the function of keeping the welding\u00a0head with axis of rotation coincident with the\u00a0axis of the tube during welding.
\nThe unit consists of a removable mandrel fixed\u00a0by screws to the support in front of the torch.
\nCentering cartridges are inserted on this mandrel to be inserted into the inside of the tube.
\nMandrels and cartridges must be chosen,\u00a0depending on the internal diameter of the\u00a0tube.<\/p>\n<\/div>\n

A large selection of centering devices allows the welding gun to be centred on any type tube having an\u00a0internal diameter between 10 and 80 mm (standard).<\/p>\n

Any other non-standard diameter can be realized on request.<\/p>\n

The centering device consists of a mandrel on which are adapted the centering cartridges.<\/p>\n

The cartridges are sub divisible according to the centering diameter.<\/p>\n
