THE DESIGN AND MANUFACTURE OF XRAY GENERATOR USED FOR INDUSTRIAL RADIOGRAPHY.

Abstract

X-ray Generator used for industrial radiography is composed of a head of X-ray emission and a control unit. In the Vietnamese market, there are now many kinds of X-ray machine produced by different countries. However, in the scope of the paper, we would only focus on the machine with the main technical specification of 130-260 kV, 5 mA and exposure time upto 5 minutes and most popularly used in Vietnam. This is an upgrading generation of Xray machine, using HV ferrite transformer and cooling by SF6 gas. It allows to exposure a steel with the thickness of 40 mm.
