Parameter Optimization and Mechanism of Synchronous Wire-Powder Arc Melting Deposition of Aluminum Alloy
Because of the great sensitivity of arc burning to airflow and wind direction, wire arc melting deposition of aluminum alloy focuses on indoor conditions, and cannot meet the needs of on-site manufacturing. Th...

Low-temperature impact toughness of laser–arc hybrid welded low-carbon bainitic steel
A low-carbon bainitic steel serving for the high-speed train was jointed with the laser–arc hybrid welding, and the low-temperature (−40 °C) impact toughness of the joint was evaluated. The results showed that...

Interface homogenization and its relationship with tensile properties of laser-arc hybrid welded Al/steel butt-joint via beam oscillation
Homogenized intermetallic compound (IMC) layer at interface was achieved in laser-arc hybrid butt welded Al/steel dissimilar metals through beam oscillation. The beam oscillation reduced the macrosegregation o...

Relationship Between Corrosion Resistance and Microstructure Characteristic of Single-Pass Laser-Arc Hybrid Welded Stainless Clad Steel Plate
Superior weld corrosion resistance to base metal (BM) of stainless clad steel plate (SCSP) was achieved by laser-arc hybrid welding with only one pass. Under optimized parameters, the charge transfer resistanc...

Formation and suppression mechanism of lack of fusion in narrow gap laser-arc hybrid welding
In this study, the main defect, i.e., lack of fusion (LOF), occurring at the sidewalls in narrow gap laser-arc hybrid welding (NGHW) was confirmed to depend on the cross-sectional shape of previous pass, which...
