Reflecting on the 1G, or flat position in welding, this is by far the most basic and widespread method due to its simplicity and accessibility. Here, the weld piece is positioned horizontally, which provides a stable and easy-to-hold object for every welder to work with, which has a signi...
Upcoming changes to diesel engine-driven welders have become a subject of recent discussion throughout the welding industry in light of ongoing efforts by the federal Environmental Protection Agency (EPA). As part of the Clean Air Rules of 2004, the EPA has adopted a national program to reduce...
they compare the stock CPU holder-thingy to some custom made frames - which apparently does not deform CPU or makes it more flat...well, they explain in the video.They also got similar temperatures even with very expensive setup. But if you want to test it yourself...and c...
Fossil fuels probably won't run out, at least not in the sense that they will be exhausted. Oil, coal and natural gas were here before us and will be here after we're gone. But that doesn't mean we can keep using them forever or even into the near future. We've harvested the ...

It is worth noting here that very often, the simulated corrosion time based on in vitro tests does not coincide with the results from in vivo tests. This is due to the fact that, under the conditions of the pseudo-physiological environment, not all factors influencing the course of corrosion...
It also utilised the same valve sizes as the smaller engine, so the mean gas velocity through the valves was higher at a given rpm because of the 500's larger volume cylinders.It was first tested in the summer of 1965 and on its third run produced 80bhp @ 10,000rpm, with the power...
RF EMF is classified as non-ionising radiation, and unlike ionising radiation, it does not carry enough energy to ionise atoms or molecules (i.e. remove electrons from their orbit) which can change the chemical composition of material [2]. Non-ionising radiation has less energy but can still...
2. If it does it will be at a very gradual rate allowing for easy adjustments. 3. If it does it would be a very good thing, for all the reasons you mention. Let me add this. In a society with frugal, debt free, financially independent people the necessary and highly beneficial pro...
