Welding X80, 4130, 8630 with NACE requirements 焊接X80, 4130, 8630并满足NACE要求

These high strength steels obtained their properties due to the heat treatment during production. When welding these type of steels the cooling speed (T8/5) needs to be as close as possible to the original heat treatment of the steel itself. In many cases these steels have to undergo a heat treatment after welding so the filler metal must be suitable for the application. Recently new welding consumables have been developed based on current knowledge and combined with the experience of the last 30 years.

这些高强钢在生产时的热处理使得其获得了良好的性能。在焊接这些钢材时,T8/5冷却速度应该尽可能地接近其钢材原来的热处理冷却速度。在大多数情况下,这些钢材都要经过焊后热处理,使得焊缝金属满足使用要求。基于30年的经验和当前的知识,新的焊材最近已经研制成功。
