weld beads 是什么? 翻成熔滴,还是焊缝晶粒?
Charpy V-notch 是不是V形槽啊?
in flat welding positions and in uphill能翻译成平焊和仰焊吗?
In samples C2V and C3V, a different behavior was detected; the proportion of columnar zones was lager in samples welded with higher arc energy, two passes per layer. 中two passes per layer咋翻啊?最好上面那一句都翻译一下,万分感激!
