Of course, there are some subtleties, but in general, with a little practice, it is easy to master the welding skills. But wait!Not all welding is created equal, and as [Quinn Dunki] learnt, Silver soldering is much more correct.
Admittedly, this job [Quinn] The work being processed is much more demanding than fixing certain components to the PCB. She has been building a model steam engine, and this task is suitable for testing anyone’s processing skills. A steam engine needs a boiler, and this is where silver welding comes in. As she explained in the video below, silver solder or “hard” solder uses a much higher melting temperature than our “soft” solder used in electronic products.This is a big advantage of boiler heat and pressure, but it does bring some problems, many of which [Quinn] When she tried to assemble her bronze beast, she managed to find it.
It turns out that heating a large piece of copper uniformly without burning the flux is actually not easy, although you can’t say that she didn’t try like the university did. In the process, she managed to share some very interesting tidbits, such as extracting acetylene from the tank too quickly may be dangerous, or the model steam boiler must be certified by a qualified inspector. In the end, her boiler could not be salvaged and was placed on a chainsaw to determine the problem. This seemed to be her initial choice of oxyacetylene heating; after the initial failure, she could hardly save the boiler.
As [Quinn] Saying, “Failure is just failure, if you don’t learn from it.” So it might be a bit unfair to hang “Failure of the week” on this, but still-she must go back to the beginning of the boiler. We already know that it is not easy to model a steam engine.
