摘要：
Laser-arc hybrid welding of 2219 aluminum alloy was carried out employing TiB2 particles. By pre-cladding a wide layer, the particles were easy to arrive weld edge, promoting the columnar grains neighboring the fusion line transferred to equiaxed, and the average grain size was reduced by about 50%.(c) 2023 The Author(s).
