(The nicksthat were put in the steel will enable it to stay in theiron much better during the welding heat, than if leftperfectly smooth.) The pick is now ready for thewelding heat. Have the fire clean with plenty of wellcharred coal, heat the place to make the weld to acherry red, then place plenty of fine powdered boraxon it, then heat to a welding heat as high as the steelwill stand, but no more.
