| 141 | Method of welding laminated cores | US35937373 | 1973-05-11 | US3866014A | 1975-02-11 | WALLER EARL C |
| A method of welding laminated stacked cores of assembled electromagnetic devices which comprises initially stamping the core laminations so that the outer seams which will be produced on the lamination ends when the stacks are abutted has a central projection with a groove on opposite sides along the length of the seam, approximately half of the projection being formed on each part of the core. The electromagnetic device, fully assembled, is mounted in a jig with its core parts clamped together and is electrically connected to one terminal of the welding apparatus. The other terminal of the welding apparatus which carries the electrode is passed along the projection melting the projection and welding the core parts together on a fused joint that follows the seam.

| A resist coating for etching use which enables high speed and high accuracy patterning is provided by applying, to a steel strip, a negative resist ink which solidifies upon exposure to light; drying the ink to form a resist coating; then irradiating the steel strip with light while moving a mask member in synchronization with a traveling speed of the steel strip, the mask member being configured to cover a surface of the resist coating to block light, to thereby solidify a portion of the resist coating not covered with the mask member to form a solidified portion; and removing an unsolidified portion other than the solidified portion with a developing solution. Subsequently, by dissolving and removing by etching a portion of the steel strip below the removed portion of the resist coating, a fine and uniform linear groove can be formed in a surface of the steel strip. | ||||||
