Method of producing and utilizing deformable workpieces for high-pressure forming and products formed thereby |
| 摘要 |
To form a body, a preform is produced by welding together two essentially flat sheet-metal blanks (2,3) at their margins. This preform is then deformed in a mold by internal high-pressure forming to produce the desired body. In this way, complex metal bodies can easily be formed. |
