One of the most widely used processes in ship hull plate manufacturing is the flame forming process (FFP). In this work. the fabrication of saddle-shaped specimens with FFP using a spiral irradiating pattern is studied experimentally. The deformation of the deformed plates by FFP based on the spiral irradiating pattern is affected by process parameters such as the pitch of spiral pass... https://herbsdailyes.shop/product-category/eye-preparations/
