摘要： PROBLEM TO BE SOLVED: To provide a means where, regarding a joining method in which a joining material including metal nanoparticles is heated and fired in a state of being held to a space between the two members to be joined, thus the members to be joined are joined, the peeling of the joining material upon a joining operation reducing joining strength is prevented.
SOLUTION: In a joining material coating stage, regarding the two members 10 (10A, 10B) to be joined, only the required range in the joining face of either 10A is coated with a joining material 12, and thereafter, the surface of the joining material 12 is coated with a surface coat material 14 in such a manner that it is superimposed at least on the range coated with the joining material 12. Then, joining strength at which peeling is not caused upon a joining operation is secured in the joining material 12 by the joining strength of the surface coat material 14 itself.

摘要： PROBLEM TO BE SOLVED: To provide a laser welding method for surface treated steel sheets, a method that enables dry fine solid particles to be used directly as spacers and that thereby eliminates special post treatment such as a drying process to help improving productivity as well as reducing manufacturing cost. SOLUTION: On one 1 of the two plated steel sheets to be welded, there are deposited fine solid particles 3 such as steel beads for shot peening by means of a cladding laser torch having a fine particle passage. Then, on this surface treated steel sheet 1, the other one 2 is superposed through the fine solid particles 3, and subsequently the superposed parts are laser-welded. Between the two plated steel sheets 1, 2, a minute gap is maintained by the fine solid particles 3; therefore, in the laser welding, gasses generated by the evaporation of the metallic components in the plated layers 1a, 2a are discharged outside through the gap, enabling a quality weld metal 5 free from blowholes to be obtained.

摘要： PROBLEM TO BE SOLVED: To provide a joining method using metal nanoparticles, which provides necessary joined strength.
SOLUTION: The joining method includes pressing members to be joined (10A) and (10B) with a pressing force of a relatively low pressure (P1) in a relatively early stage. In this pressurizing condition of using the relatively low pressure (P1) (gas venting step), an organic protective film (16) is vaporized because a joining material (12) is heated, so that the porous part in the porous structure constituted by a metal nanoparticle (18) and a binder (20) in the joining material (12) is not excessively squashed by the pressurization. Accordingly, the porous part in the porous structure functions as a gas vent passage for releasing the gas evaporated from the organic protective film (16) therethrough, and makes the gas smoothly released from the interspace between the members to be joined (10A) and (10B). The joining method further includes increasing the pressurizing force from the relatively low pressure (P1) to a relatively high pressure (P2) (pressure-increasing step), when the temperature of the joining material (12) has reached a predetermined level; and joining the members to be joined (10A) and (10B) at the high pressure force (P2) (joining step) to enhance the joined strength.
