Handling Welding Challenges of 9-Chrome-Moly Steel
|
| Ramesh Singh, Sr. Principal Engineer (Materials, Welding and Corrosion), Gulf Interstate Engineering, was recently published in the October 2011 issue of Pipeline & Gas Journal. The article, Handling Welding Challenges of 9-Chrome-Moly Steel, discusses the use of suitable material and its weldability for progressively changing designs of a power-generating unit, which has been always a challenge. 9-chrome-moly steels have been used successfully in fossil fuel boilers. In recent years, the modified alloy P91 and T91 have been used in heat-recovery steam generators (HRSGs). Welding these materials requires very specific quality control, the degree of attention is the key difference between the work on a fossil-boiler and the combined-cycle experience. Welding of P91 and T91 alloy requires a precise heat control during welding and subsequent post-weld heat treatment (PWHT). The article discuses these issues in greater detail. |
