The temperature of an arc welding process can reach up to 6,500 degrees Fahrenheit (3,600 degrees Celsius). This high temperature is necessary to melt the base metals and the filler material, allowing them to fuse together. Heat control is crucial in arc welding to achieve proper penetration and weld quality.
Cyclohexane can be converted into benzene by catalytic dehydrogenation in the presence of oxides of D block for ex V2O5, Cr2O3 etc. Cyclohexane when heated at 6000C in presence of Al2O3-Cr2O3 gives benzene.
