不好意思，囊中羞涩，奖励有限！
In particular, the objective of this work was to study the effect of shielding gas type(CO2and Ar/CO2mixture),flat and uphill welding positions, arc energy (between 1.2 and 2.2 kJ/mm),and number of passes per layer(2 and 3) on the all-well-weld-metal mechanical properties and microstructure, obtained from a metal cored wore, of the ANSI/AWS A5.29-98 E91T5K2/E101T5-K3 type.
The consumable employed in this work was a commercial product classified by the fabricator as ANSI/AWS A5.29-98()E91T5=K3 type metal cored wire, in 1.2mm diameter. In fact, according to the mentioned standard, there are two classifications:E91T5-K2 and E101T5-K3.It is supposed that the fabricator made an extrapolation taking into account the all-weld metal both in terms of chemical composition and mechanical properties of the consumable.

实际上，这项工作的目的主要是研究：保护气体类型（CO2以及Ar/CO2的混合气），平稳上升的焊接部位，拱形能量（1.2-2.2KJ/mm）,每层通过的数目（2-3）对完全焊接金属的机械性能和微观结构产生的影响。这些数据是从ANSI/AWS A5.29-98 E91T5K2/E101T5-K3类型的金属芯所获的的。
此项研究所需的材料是一种商业产品，造假者把他归为直径1.2mm的ANSI/AWS A5.29-98()E91T5=K3 型金属芯丝。实际上，根据所提到的标准，只有两种类别：E91T5-K2 和E101T5-K3。我们可以猜出，造假者是从耗材的化学成分和机械性能两项指标上来考虑全焊接金属而作出的推断。
