Method for monitoring quality of a transmissive laser weld

摘要

A method for monitoring quality of a weld ( 56 ) being formed between first and second pieces of material ( 10 and 12 ) includes the steps of obtaining a thermal image of the weld ( 56 ) being formed by collecting infrared radiation passing through the second piece of material ( 12 ); and analyzing the obtained thermal image for characteristics indicative of a properly formed weld ( 56 ).
