Special Issue Information

Dear Colleagues,

Welding is a strong branch within the industry, especially in regions with a high level of economic development. Welding includes the technologies of joining materials, surfacing, thermal spraying, soldering, and thermal cutting. Modern and advanced materials, with increasing strength, low density, and special properties, require the application of advanced methods and technologies of joining and processing. Structural steels with an increasingly high strength, even over 1700 MPa, are already used not only for structures such as crane booms, but also for car body structures. In addition, light metals and alloys, plastics, and composite materials are becoming more popular. Joining such materials and ensuring high-quality joints is difficult and requires the use of advanced welding methods and procedures.

This Special Issue aims to present the latest developments and advances in the field fusion, hybridity, electric resistance, and solid state welding of materials.

Research areas may include (but are not limited to) the following:

  • Advanced fusion and solid state welding technologies of materials;
  • Advanced electric resistance welding;
  • Advanced soldering and brazing technologies;
  • Advanced thermal cutting technologies;
  • Advanced surfacing technologies;
  • Additive methods based on welding technologies;
  • The characterization of welded materials (microstructure, mechanical properties, etc.);
  • The welding of HSS and UHSS steel grades, non-ferrous alloys, plastics, or composites.

A novel high depth-to-width ratio of 15:1 narrow-gap gas metal arc welding technique was developed for the welding of S500Q steel in a horizontal butt joint. The bead arrangement of the I groove was optimized to produce a high-quality connection with the upper sidewall of the joint. The microstructure and mechanical properties were observed and evaluated by optical microscopy, scanning electron microscopy, tensile testing, and micro-hardness and impact toughness testing at 1/5, 2/5, 3/5, and 4/5 thickness of the joint. The 3/5 T position exhibited the highest strength, which was attributed to the presence of finer carbide precipitates. The highest micro-hardness appeared at 4/5 T. The highest impact toughness appeared at 3/5 T. The formation of coarse granular bainite was the major reason for the decrease in impact toughness in other regions. A microscopic fracture at 1/5 T and 3/5 T was further analyzed. It was observed that the width of the fibrous zone at 3/5 T was significantly larger than that at 1/5 T. The radial zones at 1/5 T were observed to exhibit cleavage, with secondary cracks on the fracture surface. Full article

Advanced high-strength steels (AHSSs) are designed for meeting strict requirements, especially in the automotive industry, as a means to directly influence the reduction in the carbon footprint. As rotary friction welding (RFW) has many important advantages over other welding technologies, it plays an important role in the automotive sector. On the above basis, in this work, combinations of the first (complex phase (CP)), second (TWIP (TW)), and third (quenched and partitioned (Q&P)) generations of similar and dissimilar high-alloyed advanced steels have been joined by the RFW process. Having a specific microstructure, rods of CP/CP, Q&P/Q&P, CP/TW, and Q&P/TW steels were welded by employing a homemade adaptation machine under fixed parameters. Microstructural characterization has allowed us to corroborate the metallic bonding of all the tested advanced steels and to identify the different zones formed after welding. Results indicate that the welding zone widens in the center of the workpiece, and under the current friction action, the intermixing region shows the redistribution of solute elements, mostly in the dissimilarly welded steels. Furthermore, because of their complex chemistry and the different mechanical properties of the used steels, dissimilarly welded steels present the most noticeable differences in hardness. The TWIP steel has the lower hardness values, whilst the CP and Q&P steels have the higher ones. As a direct effect of the viscoplastic behavior of the steels established by the thermomechanical processing, interlayers and oxidation products were identified, as well as some typical RFW defects. The electrochemical response of the welded steels has shown that the compositional and microstructural condition mostly affect the corrosion trend. This means that the dissimilarly welded steels are more susceptible to corrosion, especially at the TWIP–steel interface, which is attributed to the energy that is stored in the distorted microstructure of each steel plate as a consequence of the thermomechanical processing during RFW.
