            The weld takes care of of settle Chinese foot length as 3 ms~9 ms, general settle the Chinese foot with the 6 ms.

            The weld takes care of of settle the Chinese foot length in usually length, its the deviation of admission is the 5 mms of ±.
            Adopt partial the degree of flinch in a the tube of weldfor keeping the Chinese foot measurement should not very in 2.0 mms.
