Abstract

PURPOSE: To reduce the time required in gas cutting of steel plate, as soon as gas cuttings are started from a pierced hole located on a cutting line of the steel plate, other gas cuttings from outer edges are conducted toward the hole.
CONSTITUTION: In gas cutting of a steel plate 1 in transverse direction, a through- hole 4 is first pierced at the center of a cutting line b by a drilling gas torch 3. From the through-hole 4, gas cuttings are started, by using a pair of gas cutting torches 5 and 6, in transverse direction toward both outer edges of the steel plate. Simul- taneously, corresponding to the thickness of the plate 1 and the length of the cutting line b, another pair of gas torches 7 and 8 are advanced from both sides of the cutting line toward the center hole 4 so that the respective set of torches 5, 7 and torches 6, 8 meet on the cutting line b. This cutting process drastically reduces the time requirement of gas cutting and results in an efficient cutting treatment.
