Preheat in Welding

Welding is a critical process used in various industries to join metals and create strong, durable structures. To ensure the quality and integrity of welded joints, various factors must be considered, and one of the most crucial steps in this process is preheating. Preheating in welding is a method of raising the temperature of the

Welder Qualification (WPQ) as per ASME Section IX

For fabrication of any equipment we require welders and welding operators must be qualified as per the qualification standard referred by the construction code. Whenever construction is as per ASME construction codes (like ASME B31.1, B31.3 or ASME section VIII) ASME section IX is used for the qualification of the procedure and welder. Welder is
