Abstract：

A　quasi-steady-state　laser-GMAW　hybrid　welding　simulation　method　was　developed.　The　comprehensive　effects　of　buoyancy,　thermal　capillary　force,　electromagnetic　force　and　arc　shear　force　were　considered　in　the　model,　thus　the　temperature　and　flow　fields　characteristics　of　molten　pool　were　obtained.　At　the　same　time,　the　heat　source　motion　was　realized　based　on　the　deformed　geometry　(DG)　approach.　The　model　can　be　applied　to　laser　welding　processes　with　different　joint　configurations　or　moving　paths.　©　2022　Taylor　&　Francis　Group,　LLC.
