X-Ray Tube Voltage
The X-ray tube voltage determines the energy and wavelength spectrum of the emitted radiation. Higher voltage gives higher energy and shorter wavelengths, which increases penetrating power.
Physicochemical Mechanism of Action
Röntgen tube voltage affects the electron supply in the hot chamber tube. Higher voltage accelerates the electrons, so they strike the cellular element with higher energy and emit X-rays.
Metallurgical Relevance & Welding Risks
Too high a voltage can cause excessive penetrating power, leading to damage of the material structure or an increased tendency to cracks and hot cracks in the weld. Too low a voltage reduces penetrating power and can lead to insufficient material penetration and poorer weld quality.
Workshop Practice & Instructions
The optimal Röntgen tube voltage depends on the chosen material and welding method. For common steels in TIG welding, the voltage usually lies between 100 and 250 volts. For Delrin or other plastics, a higher voltage of 300 to 400 volts may be required. It is important to regulate the voltage precisely and monitor it if necessary to ensure optimal weld quality.
