(9) turn off hydraulic compressing device, rap motor stamping with hammer, in order to make motor stamping aligned with each other；
(10) check whether the centre bore of motor stamping and outside have dislocation, regulated if desired；
(11) clamping motor punching again；
(12) checking welding wire, specification is 1.2mm gas shield welding wire；Welding current is 170-230 ampere, welds；Weld width is more than or equal to 6mm, and height is more than or equal to 2mm；
(13), after welding terminates, the welding slag on electric machine iron core surface is removed immediately with wire brush；
(14) turn off hydraulic compressing device, check that pad has the defect such as free from flaw, pore；If having, then reopen hydraulic compressing device and be welded with defect area；
(15) close hydraulic compressing device, front pressuring plate is hung the free end of lining, is placed on tool holder；
(16) hang in electric machine iron core centre position with crane shears of slinging, electric machine iron core is carefully hung taper key, it is ensured that iron core is not collided with equipment bottom, the electric machine iron core welded is taken off from lining.
Compared with prior art, the invention has the beneficial effects as follows:
Reduce electric machine iron core to collide with in welding process, it is to avoid affect outward appearance, it is possible to meet the high-end customer requirement to electric machine iron core；Reduce the labor intensity of workman, improve work efficiency；Avoiding the impact of artificial uncertain factor to greatest extent, eliminate the welding slag of remained on surface, it is ensured that the quality of welding, the later stage manually repairs grooved also without input is substantial amounts of, reduces the input of human cost, shortens the production time；And it is applicable to the production of different length electric machine iron core, reduces equipment investment, save production cost.
