Real-Time Weld Monitoring System

Utilizing real-time inline coherent imaging the IPG Real-Time Weld Monitoring System consolidates weld results into concise and actionable quality data from a single system. Pre-weld monitoring modes of the system include tracking of the seam position, checking the working distance to the material, and looking for gaps, bad fixturing or bad fit-up before processing begins.  In-weld real-time monitoring at the bottom of the keyhole records the penetration and fusion depth of the weld for loss of or over-penetration and process instability.

Weld monitoring with the LDD-700 enables manufacturers to reduce scrap and facilitates early detection of defective sub-assemblies by providing more complete and accurate records for safety-critical applications than was previously possible. By allowing QA procedures to be streamlined, manufactures can respond immediately to quality issues saving time and lowering costs.

Key Measurements

The system produces a low-power measurement beam through the same optics that deliver the welding laser which rapidly conducts measurements across multiple locations on the part. Key measurements include:

Workpiece Height

Measures the distance between the material surface and the welding optics

Seam Profile

A sweep ahead of the process looks for joint position on the work piece

Transverse Profile

Measures the finished weld bead transverse profile

Finished Weld Surface

Measured joint just behind the melt pool captures the height of the finished weld bead

Keyhole Depth

Measured inside the keyhole during the weld to determine actual weld penetration depth in real time
