Absorbing moisture of electrode coating will increase the diffusible hydrogen of deposited metal in weld joint,causing the weld defects such as cold crack,embrittlement and porosity.In view of this,improving the moisture resistance of the electrodes has become a pressing project need to be solved in the process of developing low hydrogen electrode.The methods,principle and factors influencing of diffusible hydrogen are discussed.With the research work of scholars,an overview of influence of absorbing moisture of the low hydrogen electrode is given.The research achievements and development trend are illustrated,and the summary and prospect are presented finally.
