Open the CIPO recordAbstract From the Canadian patent
A method and system for controlling the quality of a weld during a weld process includes using an automated welding apparatus (16) to apply a weld bead (10) along a weld seam (12) to join a first work piece (18) to a second work piece (18). The weld seam (12) is the area between the work pieces (18) which receives the weld bead (10). Surfaces of the weld seam are measured to determine weld seam (12) characteristics such as seam shape misfit in a seam, seam gap, and surface irregularities. A weld seam (12) profile is determined based on the measurements of the weld seam (12). A desired weld bead profile is predicted based on the weld seam profile. Optimal welding parameters for the …

Why it's free to use
- Filed December 17, 1999. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended December 17, 2019.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by December 17, 2021.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
