2. The preparation of this project is based on 2.1 F43C technical documents. 2.2 National Standard GB50236-98 "Code for Construction and Acceptance of Welding Engineering for Field Equipment and Industrial Pipelines" 2.3 National Standard GB50235-97 "Code for Construction and Acceptance of Industrial Metal Pipelines" 2.4 Welding Procedure Evaluation Report of the Company :HG1


3. Welders 3.1 Welders should have the qualification certificate of welder examination stipulated in "Rules for Welder Examination of Boiler and Pressure Vessel Pressure Pipeline Welders". 3.2 After entering the site, the welder shall first pass the actual welding operation examination according to the provisions of GB50236-98, and can only undertake the welding work of this project after being approved and issued by the general contractor.


4.溶接検査4.1溶接検査官は、F43C技術文書と関連する国内基準およびこのプロセスに精通している必要があります。 4.2規制に従ったパイプ溶接材料の検査、充填、および受け入れ。 4.3溶接工がこのプロセスを実施しているかどうかについて包括的な監督と検査を実施し、違反者を教育して支援します。


1. Help to be corrected. For serious violators or those who do not change their education, they have the right to stop the welding work. to ensure welding quality. 4.4 Do a good job in Article 7 "post-welding inspection and management" of this process. 4.5 Invite and welcome inspectors from the general contractor and the supervisor to inspect the welding quality.


5. Preparations before welding 5.1.1 Pipes and welding materials must have qualified certificates that meet the regulations, and be checked with the physical objects. 5.1.2 The type of pipe material is grade 304, which is equivalent to my country's 0Cr18Ni9 specification standard. As specified in the project drawings. 5.1.3 Model and specification of stainless steel welding wire: H{{20}}Cr20Ni10Ti φ2.5mm φ2.0mm 5.1.4 Model and specification of stainless steel electrode: A132 φ3.2mm φ2.5mm 5.1.5 Model and specification of cerium tungsten electrode: WCe-20 φ2.0mm 5.1.6 The argon gas was 99.99 percent pure. 5.2 Preparation of Weldments 5.2.1 The distribution of welding ports must comply with the national standards GB50235-97 and GB50236-98


ファンの規制。 5.2.2パイプはV-字型の溝であり、突合せ継手とグループは図1の要件に対応しています。注:3.54mmのギャップは、溶接中のデータです。 グループ-から-のポイントソリッド溶接の場合、収縮を補正するために、このデータよりも適切に大きくする必要があります。
