Hi John S, Methinks that the metal sprayers in your little story failed on two accounts, one the over spray and two the wrong powder/process. As you know there are two main processes, one metal spraying and two Powder welding. With powder welding you don't get a lot of over-spray, so I assume they used metal spraying. With metal spraying you effectively spray a ring on a shaft, the two are not necessarily fused together, which leads to its bad reputation on things like crankshafts. With powder welding the process is more akin to MIG and the weld is definitely fused to the job. The advantage of powder welding is that you can select different powders to achieve different purposes, much like you can with different rods when stick welding, but with powder welding the heat input is much less, so tempering might not be effected. Some of the powders are so tough that they can only be machined by grinding, but that might be over-kill on an armature. Yes folks, I did the Eutectic powder welding and spraying course, but about 25-30 years ago and haven't done any since. Ned |
