Earlier we considered those types of tests that allow us to know the mechanical properties of metals. The metals also have important chemical properties. In fact, it is the chemical composition of the metal and its heat treatment that largely determines its mechanical properties. The part is necessary to determine the chemical composition of the metal. To do this, there are three common methods: spectral analysis, combustion analysis and analysis of the effects of liquid reagents.
The welding inspector rarely has to practice chemical analysis. However, the inspector may need assistance in the sampling and sampling process for analysis or Continue reading →
