Forexample, the case of a 4500-pound brass casting may be cited,which, upon examination, was found to contain certain cracksnecessitating that the whole be scrapped, if not corrected, butthe oxy-acetylene torch successfully reclaimed it from the scrapheap. In another case, a good-sized casting was to form partof air compression machinery, and extensive machine opera-tions had to be carried out. When an amount, said to be $300worth, had been done, the discovery was made that a blowhole communicated with the air chamber. Here was a casewhere the defect would have resulted in considerable loss. Buthere also the new process was equal to the requirements of theoccasion. The oxy-acetylene procedure is largely indifferent to whatthe particul
