China wholesale Square Butt Weld Manufacturers - AWS E8015-B1 Low-alloy steels Manual electrode Welding stuff – Honest Metal Detail:
Application&Standard&Note：
GER-207 heat resistant steel hand welding rod (R207)0.5%Cr-0.5%Mo steel hand welding rod is suitable for welding CrMo pearlite heat resistant steel and high temperature, high pressure pipeline, chemical containers and other corresponding steel, such as 12CrMo tube plate, A335-P2 tube, A387Gr.2 plate. Welding conditions: preheating and channel (layer) temperature: 160~190℃; 3. Heat treatment: 690±15℃x1h heat treatment is carried out according to the standard requirements of welding materials.
AWS E8015-B1 type hand electrode for heat resistant steel is suitable for welding CrMo pearlite heat resistant steel (such as 12CrMo, etc.) and high temperature, high pressure pipeline, chemical container and other corresponding steel. Before welding, the electrode must be baked at about 350℃ for 1h, and then used with baking. Before welding, the weldment must be cleaned of rust, oil, water and other impurities.
Features
AWS E8015-B1 (R207) type hand welding electrode for heat resistant steel is a low sodium hydrogen type hand welding electrode, stable arc, less splash, good forming, easy desagging, X-Ray performance is excellent. Hand welding electrode is widely used in electric power, power engineering, petrochemical and other industries, the most commonly used Cr-Moh and Mn-Mo type heat resistant steel and Cr-Mo base multi-element alloy heat resistant steel. It is also necessary to adopt the method of preheating before positioning welding and formal welding for heat resistant steel welding. If the weldment is strong, it should be preheated as a whole. After welding, the weldment should be kept above the preheating temperature for several hours, and then slowly cooled.
