The present invention relates to a method for preventing a deformation of a block end, including the following phases of: positioning heating portion for setting the heating portion on the top side of a block end; pre-heating the surface of the heating portion to make the block end deform along the preset heating portion; and welding the bottom side of the block end with another block, in order to prevent deformation of the block end caused by the welding of another block. Thereby, a number of modifications are exempted, and work efficiency can be improved.
