Abstract
A manufacturing method for a metal mark plates is disclosed. In this manufacturing method, a welding flux layer is firstly disposed onto a metal base plate, and a plurality of metal mark parts are arranged on corresponding regions of the metal base plate on which the welding flux layer is disposed. Thereafter, a laser spot welding step is performed to assemble the metal mark parts with the metal base plate by heating the backside of the metal back plate at a location corresponding to the welding flux layer. This manufacturing method therefore provides a fast and stable welding way for manufacturing the metal mark plate. Besides, this manufacturing method can be applied for automatic production and precise mass production could thereby be accomplished.
