METHOD OF FORMING WELD BEAD OF PURE COPPER ON FERROALLOY BASE MATERIAL |
摘要 |
<p>In forming a weld bead of pure copper on a ferroalloy base material by laying a powder of copper and melting the powder by a high density energy source such as laser beams, TIG arc or electron beams, the powder of copper is beforehand mixed with a powder of an auxiliary metal having a higher melting point than pure copper. In order to ensure the substantial purity in copper of the weld bead, the powder mixture should not include more than 16 wt% nickel.</p> |
