Hydrogen cracking in welds - Bok av Waldemir Dos Passos Martins - Häftad
This book presents an investigation of the initial moment of formation and propagation of hydrogen cracking in welded joints of an API 5L X80 steel, using the Implant and Tekken tests coupled with the acoustic emission (AE) technique. The development of a System of Acoustic Emission - SEA and a computational program to register the acoustic signals generated by the crack events is presented. In the development of the work two welding processes were used (Tubular Wire and MIG/MAG) with consumables..
