摘要
采用四因素三水平正交试验考察了影响PVC—U异型材门窗焊接强度的关键因素（焊接温度、熔融时间、焊接时间、焊接压力等）。结果表明：①影响PVC—U异型材门窗焊角强度的最主要因素是熔融时间，之后依次是焊接时间、焊接压力、焊接温度；②适宜的工艺条件为；焊接温度245-255℃、熔融时间30s左右、焊接时间30s左右、焊接压力0．4MPa左右。
Orthogonal experiments with three levels and four factors were conducted to investigate the key factors（such as welding temperature,mclting time,wclding time,welding prcssurc and etc. ） influencing the wclding strcngth of PVC - U profilc doors ＆ windows. Thc rcsults showed that： （1）the factors influencing the welding strength of PVC - U profilc doors ＆ windows was melting time, welding timc, welding prcssure and wclding tempcrturc in order of importancc; （2） the suitable process conditions were that the welding temperature was 245 -255 ℃, melting time was 30 seconds, welding time was 30 seconds and wclding pressurc was 0.4 MPa.
