I have some thoughts, Does QW 202.4 only apply to PQR qualification on two different material thicknesses? because if so, the standard is a bit messed up. Performs PQR on P. No. 8 (additional material not valid) let's see 2 cases:
1- Performs connector no. 1 (photo). 10 mm sheet + 10 mm sheet. Which allows me to make a joint on a material based on table QW-451.1 from 1.5-20 mm. So I can make a joint, e.g. 1.5 mm sheet + 20 mm sheet. The scope of both materials is preserved.
2- Performs connector no. 2 (photo). 10 mm sheet + 11 mm sheet is acc. To QW-451.1 the range is as follows. I (10): 1.5-20 and II (11): 5-22. But I go to QW 202.4 where there is a record that by making such a joint, the second material is qualified without limit. So I can make a joint 1.5 mm sheet + 300 mm sheets.
Why make a joint of the same thickness as you can do the second case and we have an increased range by adding only a different sheet thickness, e.g. by 1 mm.
Please verify if I am wrong.
