The invention discloses an electrode cap for an anti-splashing type spot welding machine. A hole is formed in one end of an electrode cap body and is formed in the axial direction of the electrode cap body; the end face of the other end of the electrode cap body is a spherical face; the electrode cap body is further provided with a flow dividing ring which surrounds the periphery of the spherical face; the axis of the flow dividing ring and the axis corresponding to the spherical face are on a same straight line; the root portion of the inner wall of the flow dividing ring coincides with the root portion of the spherical face; the root portion of the outer wall face of the flow dividing ring coincides with the outer circumference face of the electrode cap body; the flow dividing ring is in the shape of a cone; the inner diameter of the root portion of the flow dividing ring is smaller than the outer diameter of the free end of the flow dividing ring; the distance between the vertex of the spherical face and the root portion of the spherical face is larger than that between the free end of the flow dividing ring and the root portion of the spherical face; and the difference between the outer diameter of the free end of the flow dividing ring and the inner diameter of the root portion of the flow dividing ring is 1-2 mm. The electrode cap for the anti-splashing type spot welding machine can prevent the molten metal splashing caused in the welding process.
