Correlation of Structure and Fractographic Characteristics of High-Strength Pipe Steel Welded Joint Metal Failure Micro-Mechanism

The structure and microstructure of impact fracture specimens of the heat-affected zone (HAZ) of low carbon micro-alloyed high-strength pipe steel welded joints are investigated. Correlation of structure parameters and fractographic characteristics of the failure micro-mechanism channel is establish...
