AI Technical Summary
The scale strips of existing weld gauges are easily scratched and worn during transport and storage, leading to inaccurate measurements, affecting the judgment of weld quality, and also resulting in high maintenance costs.
A weld seam measuring device was designed, comprising a main scale plate, a scale bar, a protective plate assembly, and a drive assembly. The protective plate assembly and the drive assembly work together to protect the scale bar from damage and ensure the accuracy of the measurement data.
It effectively prevents scratches and wear on the scale strip, ensures the accuracy of measurement data, reduces the risk of misjudgment caused by scale damage, and reduces safety hazards and maintenance costs.
