    摘要: A method for joining heat transfer plates (201, 401), comprising: applying a melting depressant composition (14) on individual application areas (142) of a first metal sheet (201), each application area (142) comprising a mid-section and two end-sections; pressing ridges and grooves in the metal sheet, the ridges extending in a direction that extends between the end-sections of the application areas, such that the application areas are located on top of the ridges; bringing the metal sheet (201) into contact with a second, pressed metal sheet (401), such that contact points (240) are formed where the mid-sections of the application areas (142) are located; heating the sheets (201, 401) until melted metal (210) is formed at the application areas (142) where the melting depressant composition (14) is applied; and allowing the melted metal (210) to solidify such that a joint is obtained at the contact points (240).
