Abstract
The paper ‘Understanding the behaviour of pulsed laser dry and wet micromachining processes by multi-phase smoothed particle hydrodynamics (SPH) modeling’ by Muhammad et al published in 2013 J. Phys. D: Appl. Phys. 46 095101, laid the foundation for SPH simulation of laser melting process including welding and selective laser melting. However, there are some inaccurate or inappropriate mathematical descriptions about the energy conservation in the paper, which may mislead some careless readers and cause unnecessary waste of time. In this paper, some comments and clarifications on the errors are made. By correcting these errors, a deeper understanding on the energy transport during the laser melting processes can also be obtained.
