1. An assembly to deform metal parts by a magnetic pulse by at least one of a magnetic pulse forming and a magnetic pulse welding, the assembly comprising: a coil comprising a first branch and a second branch configured to be connected to a power source, the first branch and the second branch extending adjacent to one another so as to define a slot; an active portion of the coil connected to the first branch and the second branch, an active surface of the active portion configured to be disposed opposite a metal part to be deformed; a mask configured to cooperate in a removable and replaceable manner with all or a portion of the coil without use of a glue or an adhesive, the mask having a shape that is at least partially complementary to a shape of the coil such that when the mask is in an operating position, a first portion of the mask is inserted into the slot to insulate the first branch and the second branch from each other, and a second portion of the mask cooperates with the active portion of the coil when the mask is in contact with the coil and covers all of the active surface of the active portion of coil; wherein the mask being made of one piece of an electrically insulating material; and wherein the mask is replaceable with a spare mask by withdrawing the mask from the slot defined by the coil and inserting the spare mask into the slot.
