PVC Welding Strength
Problem Phenomenon
Insufficient weld seam strength after welding PVC sheets
Cause Analysis
Improper welding temperature and speed, insufficient fusion of the weld seam; During on-site troubleshooting, verify item by item according to this mechanism, and avoid blindly adjusting the machine based solely on experience; This mechanism has been repeatedly verified by industry materials, and it should be confirmed first during troubleshooting
Solution
Calibration of welding temperature and speed parameters; welding rod material matching; sampling inspection of weld seam strength; After adjustment, take consecutive samples to verify the effect, and resume mass production only after confirming stability; Change only one variable at a time and record parameter changes, so as to locate effective measures
Key Takeaway
PVC welding is ensured by parameter calibration and sampling inspection; After confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence; Include this case in the defect archive as a reference for troubleshooting similar problems in the future
