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.
Nitrogen values were very low ,as well as residual elements of P, S ,Cr, V, Co, Cu, and Al, showing a very clean weld deposit. No influence of the heat input (two or three passes per layer)was detected on the chemical composition, but the C, Mn, and Si values were somewhat lower in the welds obtained in flat welding positions than in uphill , as was previously found (Refs.16, 21,22).

对全焊缝金属试样的每一个焊缝进行化学分析. 利用LECO设备抽取样品,确定了氮、氧含量. 其中氮含量很低,还有一些少量的磷、硫、铬、V、钴、铜和铝,因此焊缝处显得非常光亮. 像以前发现的一样,除了在凹下处碳、锰、硅的含量比凸起处低,并没有发现影响热量传递(每层屏障数(两及三层))的化学成分。
