摘要：

The beams from three separate 4kW Nd:YAG lasers have been optically combined to produce a workpiece power of 9kW CW, delivered in a single spot, via a 1mm diameter step index fibre. This high power beam has been used to investigate the welding of thick section C-Mn steel. In the down hand (1G) position, it was possible to produce fully penetrating melt runs, of good quality, at a speed of 0.7m/min in 12mm thick material. In the horizontal/vertical (2G) position, good duality, fully penetrating melt runs were obtained on 15mm thick material at a speed of 0.4m/min.
