For punching to full size, the diam

For punching to full size, the diameter of the punch shall be 1.6 mm larger than the nominal diameter of the bolt and the diameter of the die shall not be more than 1.6 mm larger than the diameter of the punch. For sub-punching, the diameter of the punch shall be 4.8 mm smaller than the nominal diameter of the bolt, and the diameter of the reamed work shall be such that after reaming, no punched surface shall appear in the periphery of the hole. Refill of a limited number of mispunched holes by welding will be permitted, but only after specific approval of such repairs. Where approval is given to refill mispunched holes by welding, the steel adjacent to the holes shall be heated immediately prior to welding. After the holes have been filled by welding, the welded area and the steel adjacent to the welded area shall be heated to relieve stresses; the welded area shall be ground flush, and the holes shall be punched as required.

結果 (繁體中文) 1:

用於沖壓到全尺寸，衝頭的直徑應比螺栓的標稱直徑與模頭的直徑不得大於衝頭的直徑大超過1.6毫米的1.6毫米。對於亞沖孔，衝頭的直徑應比螺栓的標稱直徑小4.8毫米，並且擴孔工作的直徑應使得鉸孔之後，沒有沖孔表面應在孔的周邊出現。通過焊接mispunched孔的數量有限的再填充將被允許，但只有在這種修理的特定批准。其中批准被給予重新填充由焊接mispunched孔，鄰近所述孔的鋼應加熱之前立即焊接。孔被填充通過焊接之後，焊接區和鄰近於所述焊接區的鋼應加熱，以減輕應力;

對於全尺寸沖孔，沖孔直徑應大於螺栓標稱直徑 1.6 mm，模具直徑不得超過沖孔直徑 1.6 mm。對於分沖孔，沖孔的直徑應比螺栓的標稱直徑小4.8毫米，並且衝壓工的直徑應使沖孔後，孔的週邊不得出現沖孔表面。允許通過焊接重新填充數量有限的錯打孔，但僅在具體批准此類維修後才能進行填充。批准通過焊接重新填充錯孔的，應當在焊接前立即加熱與孔連續的鋼。焊接填充孔孔後，應加熱焊接區域和焊接區域附近的鋼，以減輕應力;焊接區域應接地齊平，孔應按要求打孔。

結果 (繁體中文) 3:

對於全尺寸沖孔，沖頭直徑應比螺栓的標稱直徑大1.6 mm，模具直徑不應比沖頭直徑大1.6 mm。對於子沖孔，沖頭的直徑應比螺栓的標稱直徑小4.8 mm，鉸孔的直徑應確保鉸孔後，孔的周邊不出現沖孔表面。允許通過焊接重新填充數量有限的錯孔，但必須在此類維修得到具體準予後。如果準予通過焊接重新填充錯孔，則應在焊接前立即加熱孔附近的鋼材。焊接補孔後，應加熱焊接區域和鄰近焊接區域的鋼材，以消除應力；焊接區域應磨平，並按要求沖孔。
