Passes per layer. This was probably due to the difficulties found during midcrostructural assessment give the little morphological differences between different zones in these samples. This fact is compounded with the intrinsic characteristics of uphill welds , which result in lower current, arc voltage, and welding speed (increased weaving )for the same heat input, which gives rise to a different bead shape than in the flat postion.
Table 4 shows the percentages of microconstituents present in the columnar zone of the last bead of each weld.
在样品C2V和C3V中观测到一个不同的行为;用更高弧能焊接的样品中柱状晶区的面积要更大一些,每层有两个passes.这可能是由于微观结构估计中发现的问题,估计给出了这些样品中不同区域微观形态的不同.这个事实是和向上焊缝的内在特性联系在一起的,这导致了在相同的热输入中更低的电流,弧压,和焊接速度(增强的摇摆),这产生了和水平位置时不同的焊滴形状.
表4给出了每个焊缝最后的焊滴中柱状晶区域微观成分百分含量.
