| Abstract: | Based on the welding theory, theoretical analysis and evaluation are made on the preheated temperature for welding penstocks of the TGP left powerhouse units and tests are carried out on the cold fracture tendency of weld seams. This will provide guidance for preparing proper procedure of penstock welding. |
