carbide, such as those used on saw tips, are actually something called "cemented tungston carbide" aka "tungston carbide cobalt". what they do, basically, is take wc and press it together with red-hot, liquid cobalt. so effectively you get all the strength of the sand like wc, but as a somewhat workable metal...
it's the same as gold. combined with its fairly low cost and low toxicity, this lends it to use in weights and bullets. tungsten is used by some organisms. some bacteria incorporate tungsten into enzymes used to oxidize and reduce compounds in the cell. tungsten has the highest melting point of any metal...
submit other answers - - : : carbon in the form of a diamond, of course, is the hardest element. as far as metals go, modern high speed steels can get above a rockwell c hardness of , and osmium, as what might be the hardest pure metal, can be a hardness of or more. most people would say titanium, but...
certain environmental conditions. with medium to high carbon levels, low alloy steel is difficult to weld. lowering the carbon content to the range of % to %, along with some reduction in alloying elements, increases the weldability and formability of the steel while maintaining its strength. such a metal...

than degrees centigrade,temperatures which would render ordinary alloy steel unusable.generally the high speed steel tool is quite small and brazed or copper welded to a toolholder whick acts as a heat sink.in modern technology many highspeed tool applcation are being taken over by cermets(ceramic/metal...
sufficient to heat treat the . now days tig is the way to go but many precautions should be taken. you need to purge the inside of the tube with argon to protect the root of the weld. if you use filler you need to heat treat the weld asap with an oxy/acetylene torch. depending on the thickness of the metal...
looking to weld professionally start with mig and tig then is a much easier task to perform mig is required by law and by insurance companies in many localities for structural repair of automotive frames. mig is also much easier to learn and faster to weld. for doing other types of welding, like sheet metal...
following process and you'll do great. if right handed hold the handle slightly to the left just enough to see the wire sticking out of the nozzle, weld to the left in an overlapping circular pattern usually between / and / wide the lens should be sufficient if for arc welding. a quick practice on scrap metal...
get better welds and is faster. i would not even consider a stick weld on a frame unless there was nothing else. when done with tig...you're done...no messy flux nor nodules to clean up. heat is a factor also because frames are alloys that need a minimum temperature weld so not to crystallize the metal...
