COC Laser Welding Failure
ظاهرة المشكلة
COC parts have insufficient laser welding strength or burnt welding zones, and pores and cracks appear after welding two parts with matched light transmittance.
تحليل الأسباب
COC laser welding relies on the transmission and absorption matching of the upper and lower parts; batch fluctuations in material light transmittance and additive differences both affect laser energy coupling; mismatched welding pressure and speed produce defects.
الحل
①Match the material specifications of the transmitting part and the absorbing part and verify by batch; ②optimize laser power, speed and clamping pressure; ③clean the surface before welding; ④online inspection of welding strength and air tightness.
الخلاصة الأساسية
COC laser welding is a precise coupling of material matching and process parameters; batch light transmittance consistency is the basis of stable production; online inspection prevents batch failure.
