MAGNESIUM WELD LINE

摘要

It is an object of the invention to provide a magnesium welding wire excellent in surface cleanliness and a method for manufacturing the same. A welding wire according to the invention can be manufactured by drawing a base material such as an extruded material made of pure magnesium or a magnesium-based alloy and, after then, by shaving the surface of the thus drawn wire. Execution of the shaving operation makes it possible not only to effectively remove a lubricant and a coating used in the drawing operation but also to effectively remove an oxide generated during the drawing operation. Thanks to this, the thus obtained welding wire is excellent in surface cleanliness. As a lubricant to be used in the drawing operation, preferably, there may be used an oil lubricant or a wet-type lubricant which can be removed easily by a cleaning operation or by a grease removing treatment.
