定期检验与维护 ：

　　Regular inspection and maintenance:

　　定期对焊接设备进行维护、保养和检修，特别是在重要焊接结构生产前要进行试用，以确保设备处于良好状态。

　　Regularly maintain, upkeep, and overhaul welding equipment, especially before the production of important welding structures, to ensure that the equipment is in good condition.

　　计量准确性 ：

　　Measurement accuracy:

　　定期校验焊接设备上的电流表、电压表、气体流量计等各种仪表，保证生产时计量准确，避免因计量不准确而影响焊接质量。

　　Regularly verify various instruments such as ammeters, voltmeters, and gas flow meters on welding equipment to ensure accurate measurement during production and avoid affecting welding quality due to inaccurate measurement.

　　电阻焊设备监测 ：

　　Resistance welding equipment monitoring:

　　监测电阻焊设备的压力输出曲线和电流输出曲线，确保焊接过程参数符合要求。

　　Monitor the maximum pressure output curve and maximum current output curve of the resistance welding equipment to ensure that the welding process parameters meet the requirements.

　　焊装夹具维护 ：

　　Maintenance of welding fixtures:

　　对焊装夹具进行日常维护，及时清理焊渣，定期进行标定，确保夹具的准确性和稳定性。

　　Daily maintenance of welding fixtures, timely cleaning of welding slag, regular calibration to ensure the accuracy and stability of fixtures.

　　焊接后处理 ：

　　Post welding treatment:

　　焊接后的成品进行防锈处理，如使用防锈油或缠绕膜，特殊情况下（如节假日、梅雨季节、裸板焊接）应加强零件表面涂油防护。

　　After welding, the finished product should undergo rust prevention treatment, such as using rust proof oil or wrapping film. In special circumstances (such as holidays, rainy seasons, and bare board welding), the surface of the parts should be strengthened with oil coating protection.

　　破检与追溯 ：

　　Inspection and tracing:

　　原则上应抽取零件进行破检，对所有焊点进行破坏性检查，除非得到DPCA的同意。一旦发现抽样破检不合格，必须追溯抽样破检合格之时的零件，以锁定可疑区间。

　　In principle, parts should be selected for destructive inspection, and all welding points should be subjected to destructive testing unless approved by DPCA. Once the sampling inspection is found to be unqualified, it must be traced back to the parts that passed the sampling inspection to identify the suspicious area.

　　人员分析 ：

　　Professional analysis:

　　对于有问题的焊接件，需要焊接人员分析确认，并做好记录，得出合格的焊接结果后才能继续使用。

　　For welding parts with problems, it is necessary for welding professionals to analyze and confirm them, and keep records. Only after obtaining qualified welding results can they continue to be used.

　　电极帽使用 ：

　　Electrode cap usage:

　　原则上同一个点焊电极帽不能用脉冲焊混焊，避免不同焊接工艺之间的相互影响。

　　In principle, the same spot welding electrode cap cannot be mixed with pulse welding to avoid mutual influence between different welding processes.

　　凸焊规范 ：

　　Specification for convex welding:

　　凸焊必须用硬规范焊接，禁止用软规范焊接，以确保焊接质量。

　　Convex welding must be done using hard specifications, and soft specifications are prohibited to ensure welding quality.

　　激光焊接气体保护 ：

　　Laser welding gas protection:

　　激光焊接需要使用气体保护，以防止氧气和其他杂质对焊缝的污染和氧化。气体保护的基本要求包括保护性能、清洁度、气体流量、气体压力和气体纯度。

　　Laser welding requires the use of gas shielding to prevent contamination and oxidation of the weld seam by oxygen and other impurities. The basic requirements for gas protection include protective performance, cleanliness, gas flow rate, gas pressure, and gas purity.

　　采购与能力验证 ：

　　Procurement and Capability Verification:

　　焊接设备的采购应进行能力验证，确保设备能够满足焊接质量要求。

　　The procurement of welding equipment should undergo capability verification to ensure that the equipment can meet the welding quality requirements.

　　环境与操作人员管理 ：

　　Environment and operator management:

　　焊接质量不仅取决于设备，还取决于环境和管理，包括产品的符合性、预防措施、质量管理、流体管网和电流的质量、设备的正确选择、使用和参数的设定、操作员的素质等。

　　The welding quality depends not only on the equipment, but also on the environment and management, including product compliance, preventive measures, quality management, quality of fluid pipelines and currents, correct selection, use, and parameter setting of equipment, operator quality, etc.

　　供应商管控 ：

　　Supplier control:

　　对于二级供应商的焊接质量，应由一级供应商进行管控，确保整个供应链的焊接质量。

　　For the welding quality of secondary suppliers, it should be controlled by primary suppliers to ensure the welding quality of the entire supply chain.

　　这些控制内容和要求旨在确保焊接设备的正常运行和焊接过程的质量，从而满足产品设计和使用的要求。

　　These control contents and requirements aim to ensure the normal operation of welding equipment and the quality of the welding process, thereby meeting the requirements of product design and use.
