定期檢驗(yàn)與維護(hù) ：

　　Regular inspection and maintenance:

　　定期對焊接設(shè)備進(jìn)行維護(hù)、保養(yǎng)和檢修，特別是在重要焊接結(jié)構(gòu)生產(chǎn)前要進(jìn)行試用，以確保設(shè)備處于良好狀態(tài)。

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

　　計(jì)量準(zhǔn)確性 ：

　　Measurement accuracy:

　　定期校驗(yàn)焊接設(shè)備上的電流表、電壓表、氣體流量計(jì)等各種儀表，保證生產(chǎn)時(shí)計(jì)量準(zhǔn)確，避免因計(jì)量不準(zhǔn)確而影響焊接質(zhì)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.

　　電阻焊設(shè)備監(jiān)測 ：

　　Resistance welding equipment monitoring:

　　監(jiān)測電阻焊設(shè)備的壓力輸出曲線和電流輸出曲線，確保焊接過程參數(shù)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.

　　焊裝夾具維護(hù) ：

　　Maintenance of welding fixtures:

　　對焊裝夾具進(jìn)行日常維護(hù)，及時(shí)清理焊渣，定期進(jìn)行標(biāo)定，確保夾具的準(zhǔn)確性和穩(wěn)定性。

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

　　焊接后處理 ：

　　Post welding treatment:

　　焊接后的成品進(jìn)行防銹處理，如使用防銹油或纏繞膜，特殊情況下（如節(jié)假日、梅雨季節(jié)、裸板焊接）應(yīng)加強(qiáng)零件表面涂油防護(hù)。

　　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.

　　破檢與追溯 ：

　　Inspection and tracing:

　　原則上應(yīng)抽取零件進(jìn)行破檢，對所有焊點(diǎn)進(jìn)行破壞性檢查，除非得到DPCA的同意。一旦發(fā)現(xiàn)抽樣破檢不合格，必須追溯抽樣破檢合格之時(shí)的零件，以鎖定可疑區(qū)間。

　　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.

　　人員分析 ：

　　Professional analysis:

　　對于有問題的焊接件，需要焊接人員分析確認(rèn)，并做好記錄，得出合格的焊接結(jié)果后才能繼續(xù)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.

　　電極帽使用 ：

　　Electrode cap usage:

　　原則上同一個(gè)點(diǎn)焊電極帽不能用脈沖焊混焊，避免不同焊接工藝之間的相互影響。

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

　　凸焊規(guī)范 ：

　　Specification for convex welding:

　　凸焊必須用硬規(guī)范焊接，禁止用軟規(guī)范焊接，以確保焊接質(zhì)量。

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

　　激光焊接氣體保護(hù) ：

　　Laser welding gas protection:

　　激光焊接需要使用氣體保護(hù)，以防止氧氣和其他雜質(zhì)對焊縫的污染和氧化。氣體保護(hù)的基本要求包括保護(hù)性能、清潔度、氣體流量、氣體壓力和氣體純度。

　　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.

　　采購與能力驗(yàn)證 ：

　　Procurement and Capability Verification:

　　焊接設(shè)備的采購應(yīng)進(jìn)行能力驗(yàn)證，確保設(shè)備能夠滿足焊接質(zhì)量要求。

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

　　環(huán)境與操作人員管理 ：

　　Environment and operator management:

　　焊接質(zhì)量不僅取決于設(shè)備，還取決于環(huán)境和管理，包括產(chǎn)品的符合性、預(yù)防措施、質(zhì)量管理、流體管網(wǎng)和電流的質(zhì)量、設(shè)備的正確選擇、使用和參數(shù)的設(shè)定、操作員的素質(zhì)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.

　　供應(yīng)商管控 ：

　　Supplier control:

　　對于二級供應(yīng)商的焊接質(zhì)量，應(yīng)由一級供應(yīng)商進(jìn)行管控，確保整個(gè)供應(yīng)鏈的焊接質(zhì)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.

　　這些控制內(nèi)容和要求旨在確保焊接設(shè)備的正常運(yùn)行和焊接過程的質(zhì)量，從而滿足產(chǎn)品設(shè)計(jì)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.
