WPS–PQR 控制框架 🔥
A clear understanding of the WPS (Welding Procedure Specification) and PQR (Procedure Qualification Record) flow ensures compliance with construction codes such as ASME Section IX and project specifications. In quality-driven projects, welding qualification is not paperwork — it is risk management.
清晰理解 WPS（焊接工艺规程）和 PQR（工艺评定记录）流程，可确保符合 ASME 第 IX 卷等施工规范和项目技术要求。在以质量为导向的项目中，焊接评定不是文书工作——而是风险管理。
🔑 Key Technical Inputs to Review
🔑 需评审的关键技术输入
• Base metal grade (P-No.)
• 母材等级（P-No.）
• Thickness range
• 厚度范围
• Welding process (SMAW, GTAW, GMAW, SAW, etc.)
• 焊接工艺（SMAW、GTAW、GMAW、SAW 等）
• Service conditions (PWHT, impact requirements, corrosion allowance)
• 服役条件（PWHT、冲击韧性要求、腐蚀裕量）
🎯 Why Proper Qualification Matters
🎯 为何正确的评定至关重要
• Avoids project delays due to rejected welds
• 避免因焊缝拒收而导致项目延误
• Reduces cost of re-qualification
• 降低重新评定的成本
• Ensures audit and third-party compliance
• 确保通过审核和第三方合规性检查
• Maintains weld integrity and long-term service reliability
• 保持焊缝完整性和长期服役可靠性
• Protects company reputation
• 保护公司声誉
• Strengthens quality culture on site
• 强化现场的质量文化
📌 Step-by-Step WPS & PQR Flow (Code Construction)
📌 WPS 与 PQR 分步流程（规范施工）
1. Identify Code Requirement
确定规范要求
• Confirm applicable construction code (ASME, API, etc.)
• 确认适用的施工规范（ASME、API 等）
• Verify client and project specifications
• 核实客户和项目技术要求
2. Review Material & Welding Process
评审材料与焊接工艺
• Identify base material classification
• 确定母材分类
• Select welding process and consumables
• 选择焊接工艺和填充金属
3. Check Existing Qualified PQR
检查现有已评定的 PQR
• If available → Review essential, supplementary essential, and non-essential variables
• 如果有 → 评审重要因素、补充重要因素和非重要因素
• Confirm mechanical and NDT test results meet acceptance criteria
• 确认力学性能和 NDT 检测结果符合验收标准
4. If No Qualified PQR → Perform Procedure Qualification
如无已评定的 PQR → 进行工艺评定
• Prepare Preliminary WPS (pWPS)
• 编制预备 WPS（pWPS）
• Weld test coupon
• 焊接试板
• Conduct mechanical tests and NDT
• 进行力学性能试验和 NDT
• Record actual parameters (current, voltage, travel speed, heat input)
• 记录实际参数（电流、电压、焊接速度、热输入）
5. Acceptance Decision
验收决策
• If test results pass → Approve PQR
• 如试验结果合格 → 批准 PQR
• If rejected → Adjust parameters and re-qualify
• 如不合格 → 调整参数并重新评定
6. Finalize WPS for Production
确定用于生产的 WPS
• Define qualified ranges
• 界定合格范围
• Control essential variables
• 控制重要因素
• Issue approved WPS for production use
• 发布经批准的 WPS 供生产使用
7. Implementation & Control
实施与控制
• Verify Welder Qualification Test (WQT) matches the approved WPS
• 验证焊工资格考试（WQT）与批准的 WPS 相匹配
• Monitor welding parameters during production
• 在生产过程中监控焊接参数
• Maintain full traceability and qualification records
• 保持完整的可追溯性和评定记录
✒️ Why This Structured Flow Is Critical
✒️ 为何这种结构化流程至关重要
• No guesswork in welding
• 焊接无猜测
• No undocumented parameters
• 无未记录的参数
• No surprises during inspection
• 检查无意外
• Full compliance before production begins
• 生产开始前完全合规
📢 A strong WPS–PQR system ensures that welding quality is engineered into the project before the first arc is struck.
📢 一个健全的 WPS–PQR 系统可确保在首次引弧之前，焊接质量就已融入项目设计之中。
