ABSTRACT:
There is disclosed a spot welding device for spot welding metal parts by explosive force. The device comprises two plugs tightly fitted into a rigid tubular member and so spaced and shaped that a transverse substantially conical space is formed between the two plugs. This space is filled with a suitable explosive material which can be exploded by a detonator activated when desired by an igniter. The explosive force generated upon detonation of the explosive material produces a generally annular spot weld when the device is placed with one of its ends upon metal parts to be welded.
