Abstract: This paper introduces the applications of magnetic particle testing and penetrant testing technologies in key structural parts of construction machinery, and analyzes the principles and processes of magnetic particle testing and penetrant testing. Also the utility of magnetic particle testing and penetrant testing in nondestructive testing of structural parts of construction machinery is analyzed. The magnetic particle testing and penetrant testing examples of structural parts under different manufacturing process were introduced emphatically, such as crane boom, rotary drilling rig driving sleeve, concrete pump truck skirt valve and drilling rig drill pipe.
