摘要：
Deep, narrow, hollow articles are made of metal by explosive forming a shallow vessel, trimming the sheet to the desired shape at the edges thereof, dividing it, reorienting the divided members so that the flanges of the formed sheet which were opposite each other, are now in juxtaposition, and joining the contacting edges from end to end thereof.
