Embodiment
It should be noted that, when not conflicting, the embodiment in the application and the feature in embodiment can combine mutually.
Weld a control method for enamelled wire, according to the energy step increments model preset, thus the laser energy step increments that control sends, to realize the welding of enamelled wire.
Further, this step of laser energy step increments that described control sends, its be by control export electric current in time this mode of step increments realize.
Further, the energy step increments model that described basis is preset, thus this step of laser energy step increments that control sends, with reference to figure 1, it comprises the following steps:
S1, being started from scratch by the electric current of output within the first current rise time increases to first stage electric current, and within the first duration, keep the electric current that exports constant;
