此试件应使用与原始试验相同的焊接参数进行焊接，并且仅对焊接金属冲击试样进行试验。
This test piece shall be welded using the identical welding parameters as the original test and only weld metal impact test specimens shall be tested.
附加试样可从同一个试件上切取(如果有足够材料的话)或从一个新试件上切取。
The additional test specimens can be taken from the same test piece if there is sufficient material or from a new test piece.
说明了全尺寸实体试件试验具有很高的实用价值，是无法用小试样性能试验替代的。
Full size substance specimen tests shall not be replaced by mechanical properties tests with small size specimen.
在裂纹扩展试验中，试样切口后使其弯曲并产生微小裂纹，在试件上继续加力直到裂纹扩大为止。
For crack-opening displacement tests, a specimen is notched and then fatigued by flexing to obtain a fine crack. Force is then applied until the crack begins to grow.
