PC Welding and Joining
Problem Phenomenon
[Problem Phenomenon] PC parts require welding assembly; process selection evaluation
Cause Analysis
PC can be ultrasonically welded, vibration welded, hot plate welded, laser welded and solvent bonded; laser welding is aesthetic for transparent parts; select the process according to structure; when troubleshooting on site, verify each item according to this mechanism one by one, and avoid blindly adjusting the machine based on experience alone
Solution
Select laser welding for transparent parts; ultrasonic or vibration welding for structural parts; select matching solvents for solvent bonding; after adjustment, take samples continuously 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
PC welding processes are complete; laser welding is aesthetic for transparent parts; after confirming effectiveness, solidify 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
