Numerical investigation on transport characteristics of high-temperature fine particles generated in a transiently welding process

•Four influencing factors on the transport of high-temperature particles are investigated.•Motion mechanism is well revealed by analyzing dynamic variations of particle forces.•The maximum horizontal diffusion distance (ΔRmax) is adopted to evaluate exposure risk.•ΔRmax and movement of particles are...
