Steel connection joint inspection

Steel composition detection method:

1) Spectrophotometry

Spectrophotometry is a quantitative analysis method for metal elements, which qualitatively and quantitatively analyzes the measured substance by measuring its absorbance and luminous intensity within a specific wavelength

2) Atomic Spectroscopy

The principle of atomic absorption spectroscopy is to quantitatively analyze the content of the measured element by the absorption intensity of the corresponding atomic resonance radiation lines of visible and ultraviolet light by the outer electrons of the ground state atoms in the gaseous state.

3) Titration method
