焊接工艺评定的基本要求（Basic requirements for welding procedure qualification） What are the basic requirements in welding process qualification? Excuse me: what are the basic requirements in the evaluation of welding procedure? 2008-11-25 16:50 #1 Brming Assistant Engineer Essence 0 Integral 101 Post 50 Water level 100 Technology is divided into 0 Welding procedure qualification and procedure of steel structure for special equipment With the implementation of the regulations of the State Council on the supervision of special equipment safety, the welding of steel structures of special equipment is becoming more and more important. The formulation and implementation of steel structure welding technology assessment is an effective measure for ensuring engineering quality of welding special equipment of steel structure, how to reasonably comply with the standard of welding procedure qualification has been effectively applied, should pay attention to the following questions. Objective of welding procedure qualification The evaluation of the welding process is mainly to verify whether the prepared weldment meets the requirements of the welding procedure (instruction), indicating that the welding performance of the welded joint meets the requirements of the standard. The welding process is assessed through a set of technical specifications in the welding process, the welding preparation, welding materials, welding equipment, welding method, welding sequence, welding operation of post weld heat treatment after welding, inspection and evaluation. Special equipment for steel structure welding welding process is that the steel structure of the steel structure can meet the requirements of the performance requirements, but also provide quality supervision and management departments of the construction approval, supervision and management in the process of construction, completion and acceptance of the necessary documents.
