From each all-weld-metal test coupon , a Minitrac()tensile specimen (total length =55mm, gauge length=25mm, reduced section diameter= 5mm,gauge length-to-diameter ratio =5:1)and enough Charpy-V specimens with the notch located as shown in Fig .1B, to construct the absorbed energy vs. test temperature curve between-80’
And20’C,were machined. Across section was also obtained from each specimen to conduct both a microhardness survey, at the Chary v-notch location, using a 1000-g load and the metallographic analysis. Tensile tests and Charpy-V impact tests were performed in the as –welded condition. Prior to testing at room temperature, tensile specimens were heat treated for 24 h at 200’C (328’F) to let hydrogen diffuse away.
All-weld-metal spectrometric chemical analyses were conducted on a cross section of each weld coupon. Nitrogen and oxygen determinations were made with LECO equipment extracting the samples from the broken ends of the tensile specimens.

从每种全部焊接点金属测试附单, Minitrac()抗拉样品(55毫米的总长度=, 轨距长度= 25毫米, 降低部分直径= 5毫米,计量器长度对直径比率5:1 =)和V Charpy 样品的足够与找到如图中所示的槽口一起。 1 B,建造被吸收的能量与试验温度曲线between-80 ' And20 ' C,被机械加工。 穿过部分也被从每件样品获得都进行一次microhardness 调查, 在谨慎的v 槽口位置,使用一1000 克装和metallographic 分析。 抗拉考试和Charpy-V冲击试验被执行在里作为 - 焊接状态。 在在室温测试之前, 抗拉的样品是因24 h接受治疗的热在200 ' C(328 ' F)让氢离开扩散。 光谱量测的化学分析的全部焊接点金属实施在一每张焊接点附单的横剖面。 氮和氧决心由LECO 设备从抗拉的样品的被中断的末端中抽出样品做出。
