Abstract: A method of welding comprising contacting a first electrode to a porous body flow path, contacting a second electrode to a plate material, pressing the porous body flow path and the plate material by the first and second electrodes in a thickness direction of the plate material, and spot welding the porous body flow path and the plate material, wherein: a deformation of the plate material in a direction of the second electrode pressing the plate material is smaller than a deformation of the porous body flow path in a direction of the first electrode pressing the porous body flow path.

Abstract: A method for joining different kinds of metal materials includes: preparing a rivet, a plurality of metal members, and a first electrode and a second electrode, each having shanks and electrode portions provided at the tips of the shanks; sandwiching the rivet and the plurality of metal members between a first electrode and a second electrode; and embedding the rivet into the metal member by pressurization and energization using the first electrode and the second electrode. The preparation step includes preparing, as the first electrode and the second electrode, two electrodes that satisfy a condition in which each of electrical resistance values of the first and second electrodes is lower than or equal to a sum of an electrical resistance value of the plurality of metal members to be joined and an electrical resistance value of the rivet.
