Shipbuilding Process - Plate Stocking, Surface Treatment and Cutting

2021年5月9日  Cutting can be done in three different ways: 1. Shearing: In this method, the plate is rested on the edge of a flat surface, and a high velocity shearing surface (usually made of high strength steel) is used to shear the plate from the section lying on the edge of the flat surface. Follow Figure 3 below.
