各種金屬材料采用激光焊的可能性
發布時間：2015-11-23
脈沖激光焊主要用于微型件，精密元件和微電子元件的焊接。低功率脈沖激光焊常用于直徑0.5mm以下金屬絲與絲（或薄膜）之間的點焊，脈沖激光焊已成功地用于焊接不銹鋼，鐵鎳合金，鐵鎳鉆合金，鉑、佬、鉭、鋸、鎢，鉬，銅及各類飼合金、金、銀、鋁硅絲等．脈沖激光焊可用于顯像管電子搶的組裝、按反應堆零件，儀表游絲，混合電路薄膜元件的導線連接等。用脈沖激光封裝焊接繼電器外殼，鋰電池和但電容外殼，集成電路等都是很有效的方法。

由表可見，激光焊接可在許多類異種金屬間進行，銅—鎳、鎳—鈦、鈦—鉬、低碳鋼—銅等異種金屬在一定條件下均可進行激光焊。
連續激光焊主要用于犀扳諜熔焊，激光焊由于不受電子束焊真空室對零件的局限、無需在真空條件下進行焊接，故其應用前景更為廣闊，尤其是激光焊設備常與機器人結合起來組成柔性加工系統，使激光焊的應用范圍進一步擴大。
