Special Issue Information

Dear Colleagues,

Nowadays advanced high-strength steels (AHSSs) are being predominantly employed by the automotive industry. Among the main advantages, AHSSs provide improved fuel efficiency (due to weight reduction by downgauging) and accomplish passenger safety requirements (enhanced crashworthiness behavior) without compromising its properties. The AHSS family includes the following types of steel: Dual Phase (DP), Complex-Phase (CP), Ferritic-Bainitic (FB), Martensitic (MS), Transformation-Induced Plasticity (TRIP), Hot-Formed (HF), Twinning-Induced Plasticity (TWIP), boron-based Press Hardened Steel (PHS), and Quenching and Partitioning (Q&P). They possess sophisticated and unique multiphase microstructures that provide them with extraordinary strength, ductility, toughness, fatigue, and/or a combination of such properties.

Welding and joining of AHSSs is challenging, particularly when choosing a suitable technique according to established requirements (e.g., portability, cost, heat input, welding speed, joint and design restrictions, etc.). There are numerous available technologies utilized for joining AHSSs, including the following: resistance spot welding (RSW), laser welding, friction stir spot welding (FSSW), arc welding processes (GMAW, TIG, plasma), arc stud welding, high-frequency induction welding (HFIW), magnetic pulse welding (MPW), brazing procedures (GMA, plasma, laser), adhesive bonding, hybrid welding, mechanical joining, etc.

This Special Issue on the welding and joining of AHSSs aims to cover various topics of interest, which include (but are not limited to) the following: microstructure–property relationships, welding metallurgy (weld pool solidification, phase transformations, etc.), performance and properties (strength, impact, fatigue), dissimilar metal joining (i.e., AHSS and others), forming and manufacturing of tailored welded blanks, weldability of AHSSs, progress in related welding processes, welding and joining process simulation, neural network applications, industrial applications, and weld inspection and repair.

Submissions of original research articles and reviews are invited for this Special Issue.

I look forward to receiving your contributions.

Martensitic chromium-molybdenum steels such as 15Kh5M are widely used in high-temperature oil and gas equipment, but their weldability is limited by high hardenability and susceptibility to cold cracking, which usually necessitate energy-intensive preheating. This study evaluates an alternative route based on the combination of root-pass mechanical vibration (50 Hz, ~1 mm amplitude) and post-pass water-air jet cooling during mechanized GMAW. Three welding variants were compared: conventional preheated welding, vibration-assisted welding without preheating, and hybrid thermo-vibrational welding with active cooling. Among the tested conditions, the hybrid route produced the narrowest heat-affected zone, reducing its width from about 7 mm to about 3 mm, which is consistent with a compressed thermal cycle. Microhardness in the heat-affected zone decreased from 380 to 440 HV in the preheated condition to 330–370 HV in the hybrid condition. Optical microscopy further indicated a finer and more homogeneous transformed microstructure in the hybrid case. Results indicate that simultaneous vibro-treatment and controlled cooling effectively mitigate harmful metallurgical effects typically induced by rapid cooling, enabling preheat-free fabrication of thick-walled components. The proposed hybrid approach may offer energy savings, shorter production cycles, and improved automation compatibility in field welding applications. Full article
