Nickel Based welding wire used in oil gas and offshore oil

As the world energy and synthetic oil constantly expanding, face to face also increased demand for crude oil, the demand of crude oil is also increasing.
But because of the products are very expensive, then we often choose the bead weld to reduce the cost.
For a instance, we can take advantage of the characteristics of the iron based material(stainless Steel 304)strength to make the structure. And made of nickel chromium molybdenum alloy welding layer again to improve corrosion resistance. Such as ERNiCrMo-3(Inconel 625), ERNiCrMo-4(HastalloyC-276) and ERNiCrMo-10(Inconel 622) and so far the strongest corrosion resistance ability is ERNiCrMo-14.
