• SDA stands for Structure, Dynamics, and Activities analysis

• It helps in identifying bottlenecks, inefficiencies, and areas for improvement in a system

• Common techniques used in SDA analysis include process mapping, data analysis, and performance metrics

• Example: Conducting an SDA analysis on a manufacturin

P91 welding typically uses a low hydrogen type electrode.

• Low hydrogen type electrode is commonly used in P91 welding

• The electrode helps prevent hydrogen-induced cracking in the weld

• Examples of low hydrogen electrodes include E7018 and E7016

PWHT stands for Post Weld Heat Treatment, a process used to relieve residual stresses and improve the mechanical properties of welded joints.

• PWHT involves heating the welded joint to a specific temperature for a certain period of time, followed by controlled cooling.

• The process helps to reduce hardness, increase ductility, and improve toughness of the welded joint.

• PWHT is commonly used in industries such as oil and gas...read more
