Welding Technologies For Lexan/ABS

I have a small Lexan 141 dome I snap into a large piece of polycarbonate-ABS:

I'd prefer to adhere with some other method, are any of you materials guys familiar in welding technologies? Would something like ultrasonic or vibration welding be a possibility for me?

In both the acrylic fabrication shop and the sign shop that I worked in, we just used Weld-On #3 or #4. SuperGlue works in an emergency.
