Verfahren zur Herstellung eines Hohlkörpers aus zwei Metallplatinen
摘要
Hollow components are formed from sheets of material (2,3) that have been joined together by laser seam welding along the edges (6). The material is located within a high pressure hydraulic die set (9). Here a high pressure lance (19) pierces the weld seam and allows fluid to enter between the sheets. The high fluid forces cause the sheets to deform and adopt the shape of the die (8)
