Um, the terminology used in this brief article is not only confusing, it's also not scoring points for me in the accuracy and knowledge of the author... For example the title of this topic: "New Welding Process" and yet there isn't "welding of dissimilar metals." Instead, it's actually a new bonding process to be used for joining to different metals together. So the use of conflicting terminology can be at the very least confusing to some folks that don't always pay that much attention to details...
And there's more:
" Seen under a high-powered microscope, the bond is actually quite beautiful, and often features delicate curlicues in spots where
veins of both materials extend outward and wrap around each other." Now that statement alone is revealing in itself in distinguishing the difference between a
bond and the
"coalesence"otherwise known as fusion of two metals or alloys which would define some sort of welding process being used... In FSW, there is a significant difference in the make up of the metallography found in the fusion zone in comparison to this new
"bonding" process... And the using of just high voltage capacitors alone can be enhanced to offer more improved performance and customizable instead, with the use thyristor controls, or inverters as well as high speed digital processing and as low resistant conductors as possible. Even the relatively new room temperature superconductor material (Actually it hasn't been developed yet, but soon! -70 Celsius is the closest so far and that involves cryogenics which complicates the design) can also be used as part of more accurate and precise components combined together in releasing a specific amount of electricity that can be customized for even more optimal
"bonding."So in the last paragraph the term "bonding" was used mainly to describe this new process.. Here is where it can be confusing to some including the author f this article when this paragraph is read... "So far, the engineers have successfully
bonded different combinations of copper, aluminum, magnesium, iron, nickel and titanium. They have created strong
bonds between commercial steel and aluminum alloys—a feat which is
impossible normally. Also, high-strength steel and aluminum join together with
weld regions that are stronger than the base metals." IMHO, the term
joining would be better to use as opposed to using
weld instead...
And finally, the use of the phrase "impossible normally" raises the question as to whether or not the author has knowledge of a variation of the GMAW process developed by Fronius and described another method of transferring the filler metal known as Cold Metal Transfer, or "CMT." They - meaning the developers of this process variation of explosive welding, or bonding? Also claim this: "The technique is powerful enough to shape metal parts at the same time it welds them together, saving manufacturers a step." When I see it, I'll believe it.
