Abstract

One of the main problems associated with the welding of ferritic steels is that of hydrogen assisted cracking (hac), popularly known as cold cracking or delayed cracking. As the name suggests, it is caused by hydrogen present in the weld metal. One of the methods to mitigate this type of cracking is to control and minimize the amount of diffusible hydrogen content in the welds. This in turn calls for standard test methods to measure diffusible hydrogen present in weldments made with different welding consumables, processes etc. The methods employed to measure hydrogen vary from simple manometer to sophisticated mass spectrometers and sensors. The present volume of this paper highlights identification, causes and factors responsible for hydrogen cracking. Each factor influencing the risk of hydrogen cracking is described in detail with clear figures and mathematical formulation. Different methods of measurement of diffusible hydrogen and methods of hydrogen testing are also covered. The paper explains the welding procedure of hydrogen testing using saw (submerged arc welding) process. T
