On the basis of experiments, two kinds of butt joint forming physical models and three types of dimple models of fractography have been proposed. These models reveal the essence of welding process and the forming mechanism of white speck.
在试验研究的基础上,提出了两种形式的接头形成物理模型和3种类型的接头断口韧窝模型,由此可揭示接头的形成木质和“白斑”形成机制。
However, the so called white speck, as sometimes appeared on the fractography of the checked sample weld, may lead to fracture or burst of steam pipes during high temperature operation.
但在抽检样品时接头断口上有时存在所谓的“白斑”组织。“白斑”的存在可导致蒸汽管在高温运行时发生破裂或爆管。
Meanwhile, optimizing selection of process parameters are made to reduce fibre white specks.
同时，对减少纤维泛白的工艺参数，进行了优化选择。
Photographs of the test scoop showed white specks in the soil, which could be salt or ice.
