Real-time laser weld measurement directly measures 20+ weld metrics before, during, and after the welding process. This innovative solution provides unmatched in-process Quality Assurance (QA) to enable manufacturers to weld faster, more cost-effectively, and with unmatched confidence.

Despite the stability and repeatability of laser welding, unexpected material properties can result in imperfect welds. Traditional weld QA often involves time consuming post process steps like resistance testing or destructive cross sectioning that provide incomplete data.

Alternative in-process laser weld measurement technologies like photodiode rely on indirect measurement of weld quality indicators like weld plume, back reflection, and heat-affected zone. These imprecise process characteristics provide unreliable correlations with weld quality and must be calibrated on a per-process basis. Since pass/fail parameters are based on indirect data, confidence in final part quality requires unnecessarily aggressive failure conditions that result in a high rate of false failure and part scrap or rework.

By comparison, LDD real-time weld measurement provides direct, distance-based measurements of critical geometries like weld depth. LDD technology does not rely on in-process indicators and offers direct monitoring of pre-weld, in-weld, and post-weld measurements in parallel. Micron-scale precision on direct weld quality measurements enables significantly tighter QA tolerances that dramatically reduce false failures.
