Welding quality of the inner hole of the heat exchange tube
Thread Content
The internal hole welding technique is widely used in applications with special structural requirements and high standards. Replacing traditional end-face welding structures with internal hole welding structures is the fundamental way to improve the resistance of the weld joints between heat exchanger tubes and tube sheets to stress corrosion and crevice corrosion. Replacing traditional end-face welding structures with internal hole welding structures is indeed the fundamental approach to enhancing the stability of such weld joints against stress corrosion and crevice corrosion.
The original poster is correct; internal hole welding addresses some of the issues associated with gap corrosion. . . I would like to know how to repair and rectify corrosion that occurs in internal hole welding Thank you
