Metal laminating and modeling method

A metal laminating and modeling method for forming a modeled object by sequentially laminating metal layers, the method comprising:

• a first inclination angle modeling step including a first inclination step of setting a table on which the metal layers are to be formed at a first table inclination angle and setting a welding torch at a first torch inclination angle and a first welding step of forming a weld bead that becomes a part of the modeled object by arc welding with the welding torch;
• and
• a second inclination angle modeling step including a second inclination step of inclining the table at a second table inclination angle that is larger than the first table inclination angle and setting the welding torch at a second torch inclination angle set according to the second table inclination angle and a second welding step of forming the weld bead by arc welding with the welding torch.
