Grain refinement of laser-arc hybrid welded 2219 aluminum alloy by introducing TiB2 particles employing laser pre-cladding
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%.
