Abstract

TIG arc welding has been used to date as a method for clad welding of white metal as bearing material. We propose a new clad welding process that combines a CO2 laser and a TIG arc, as a method for cladding at high speed. We hypothesized that this method would permit appropriate control of the melted quantity of base metal by varying the laser power. We carried out cladding while varying the laser power, and investigated the structure near the boundary between the clad layer and the base metal. Using the laser-TIG combined cladding, we found we were able to control appropriately the degree of dilution with the base metal. By applying this result to subsequent cladding, we were able to obtain a clad layer of high quality, which was slightly diluted with the base metal.
激光- tig复合熔覆中激光功率对熔覆金属的影响
TIG电弧焊是迄今为止用于白色金属包层焊接的一种方法。我们提出了一种结合CO2激光和TIG电弧的复合焊接新工艺,作为一种高速熔覆的方法。我们假设这种方法可以通过改变激光功率来适当地控制母材的熔化量。在不同的激光功率下进行熔覆,并研究了熔覆层与母材边界附近的结构。使用激光- tig组合熔覆,我们发现我们能够适当地控制与母材的稀释程度。通过将这一结果应用于随后的包层,我们能够获得高质量的包层,它与母材稍微稀释。
