Method of facilitating the removal of beads that adhere to ferrous metal cut thermochemically

Claim 1

THE METHOD OF THERMOCHEMICALLY CUTTING THROUGH FERROUS METAL WORK-PIECES AND PREVENTING BEADS OF SOLIDIFIED MOLTEN MATERIAL FROM BECOMING SO WELDED TO THE WORK ALONG THE BOTTOM EDGES OF THE KERF THAT IT IS DIFFICULT TO REMOVE, WHICH COMPRISES DIRECTING A JET OF CUTTING-OXYGEN DOWNWARDLY TOWARD THE WORK-PIECES AND ADVANCING IT ACROSS THE WORK-PIECE WHILE THE METAL IS AT KINDLING TEMPERATURE, AND PRODUCING STEAM POCKETS IN THE MOLTEN MATERIAL THAT IS NOT BLOWN AWAY FROM THE KERF AND THAT CLINGS TO THE WORK ALONG THE BOTTOM EDGES OF THE KERF BY PROJECTING A STREAM OF WATER DOWNWARDLY INTO THE KERF SO THAT ALL PARTS OF THE WATER STREAM CONTACT WITH THE WORK-PIECE BELOW THE UPPER SURFACE THEREOF AND CONTACT WITH THE MOLTEN MATERIAL ONLY AFTER THE MOLTEN MATERIAL HAS SUBSTANTIALLY REACHED THE BOTTOM EDGES OF THE KERF WHILE IT IS STILL CLINGING TO THE WORK AND BEFORE IT HAS SOLIDIFIED, WHEREBY THE BEADS INTO WHICH SUCH MOLTEN MATERIAL SOLIDIFIES ARE POROUS AND CAN LATER BY READILY REMOVED FROM THE WORK, THE STREAM OF WATER BEING PROJECTED INTO THE KERF ANGULARLY WITH RESPECT TO BOTH THE WORK-PIECE AND THE CUTTINGOXYGEN JET.

Claim 2

THE METHOD OF THERMOCHEMICALLY CUTTING THROUGH FERROUS METAL WORK-PIECES AND PREVENTING BEADS OF SOLIDIFIED MOLTEN MATERIAL FROM BECOMING SO WELDED TO THE WORK ALONG THE BOTTOM EDGES OF THE KERF THAT IT IS DIFFICULT TO REMOVE, WHICH COMPRISES DIRECTING A JET OF CUTTING-OXYGEN DOWNWARDLY TOWARD THE WORK-PIECES AND ADVANCING IT ACROSS THE WORK-PIECE WHILE THE METAL IS AT KINDLING TEMPERATURE, AND PRODUCING STEAM POCKETS IN THE MOLTEN MATERIAL THAT IS NOT BLOWN AWAY FROM THE KERF AND THAT CLINGS TO THE WORK ALONG THE BOTTOM EDGES OF THE KERF BY PROJECTING A STREAM OF WATER DOWNWARDLY INTO THE KERF SO THAT ALL PARTS OF THE WATER STREAM CONTACT WITH THE WORK-PIECE BELOW THE UPPER SURFACE THEREOF AND CONTACT WITH THE MOLTEN MATERIAL ONLY AFTER THE MOLTEN MATERIAL HAS SUBSTANTIALLY REACHED THE BOTTOM EDGES OF THE KERF WHILE IT IS STILL CLINGING TO THE WORK AND BEFORE IT HAS SOLIDIFIED, WHEREBY THE BEADS INTO WHICH SUCH MOLTEN MATERIAL SOLIDIFIES ARE POROUS AND CAN LATER BY READILY REMOVED FROM THE WORK, THE STREAM OF WATER BEING PROJECTED INTO THE KERF ANGULARLY WITH RESPECT TO BOTH THE WORK-PIECE AND THE CUTTINGOXYGEN JET.
