AI Technical Summary
When multiple blanks are partially overlapped and joined together to form a single blank, cracks and other fracture problems are prone to occur, especially in the hot stamping process of complex shapes and large parts. This not only affects the quality of the parts, but also leads to a decrease in productivity.
By simulating and analyzing the material flow behavior of some billets, we can pre-determine where the material flow difference is small and join them. We can then use local joining methods such as spot welding and overlapping welding to avoid joining in areas with large material flow differences, thereby suppressing the occurrence of fracture.
It effectively suppresses cracks and fractures in the integrated blank during hot stamping, ensuring efficient production of large, complex-shaped parts, improving productivity and achieving excellent impact resistance.
