it has two oxygen atoms bonded to a carbon atom. inert means not chemically reactive. argon, helium, and nitrogen are inert. co is not. that is why the american welding society calls wire feed welding gas metal arc welding...not metal inert gas welding. [ more ] [ close ] reply answer : answer more...
submit other answers - - : : can not know the gear base material, welding can not talk about the problem can not answer, and specify a reasonable welding process. only that the specific material of the gear metal grades, can be based on the gear base metal, select the electrode (wire) grades [ more ]...
submit other answers - - : : vacuum sintering is to prevent the alloy in the metal element co and oxygen in the air oxidation, thereby reducing product performance. pressure sintering is in the vacuum on the basis of pressure to increase, the purpose is to change the structure of carbon products in the...
submit other answers - - : : any metal or semi-metal that is alloyed with carbon for the most part is called a carbide. tungsten carbide is one of the most common carbides, so you are right, they usually just call tungsten carbide plain old "carbide" a few carbides-- tungsten carbide titanium carbide...
submit other answers - - : : alloys are mixtures of two metals and not minerals. gold and iridium are the only two metals found naturally as alloys. gold is alloyed with a semi metallic element called tellurium and iridium forms a natural alloy with the metal osmium called osmiridium. actual minerals...
arc weld together two pieces of a boken garden seat frame..which is cast iron. does anyone know what is the best method ie which rods to use ect ect.......thanks. submit other answers - - : : welding cast is difficult because of the impurities. these impurities make the weld unable to melt the base metal...
the phases. solid solution alloys give a single solid phase microstructure, while partial solutions give two or more phases that may or may not be homogeneous in distribution, depending on the thermal (heat treatment) history of the material. an intermetallic compound will have another alloy or pure metal...
answer reward question has expired why do welders use helium and argon gases to blow over metal during the welding process? is it because of the way the gasses effect the chemical bonding properties of the metal?...
