This is a summary of a paper of the same title, authored by K. Májlinger, E. Kalácska, and P. Russo Spena, used by permission.M-65 Researchers at the Budapest University of Technology and Economics and the Free University of Bozen-Bolzano tested gas metal arc...
Microstructure and Softening QP1180 Lap Joints Welded with CMT
Quenching and partitioning (QP) steels are one of several third generation advanced high strength steel formed by controlled martensite phase fractions and retained austenite. Researchers from the University of Shanghai Jiao Tong tested the effect of HAZ softening in...
Role of Coatings in the Formation of Defects in AHSS Welds
A common issue when welding Advanced High-Strength Steels (AHSS) is with protective coatings causing weld defects. A group of researchers at the NMAM Institute of Technology and Dong-Eui University studied common issues with gas metal arc welding (GMAW) in the cold...
HAZ Properties of GMAW DP 600
In production, part geometry or joint application requires the use of gas metal arc welding (GMAW) to weld the joint. A commonly used Advanced High-Strength Steel (AHSS) is Dual Phase (DP) 600 which contains a hard martensite phase in a ferrite matrix (approximately...
Fatigue of GMAW-P Lap Joints
This article summarizes a paper by W. Mohr and N. Kapustka, EWI, entitled, "Fatigue of GMAW-P Lap Joints in Advanced High-Strength Steels."M-13 EWI has performed fatigue tests on welds from four Advanced High-Strength Steels (AHSS) in the uncoated condition. The...
