How can PLEXIGLAS^® moldings be welded?

PLEXIGLAS^® moldings can be joined by all conventional welding processes (hot-gas, high-frequency, ultrasonic, friction or laser welding). During welding, it must be ensured that the contours to be joined are identical. If not, the welded PLEXIGLAS^® part may be exposed to permanent mechanical stress after welding. Such mechanical stress cannot be relieved subsequently even by means of annealing.

Internal stress is usually generated even if welding is properly performed. It is therefore recommended to anneal welded parts.
