摘要： Provided is a method of manufacturing a joined member by joining a first metal member and a second metal member, the method including: melting an end portion on a joining side of the first metal member, while the first metal member is disposed adjacent to at least a portion of the second metal member, by irradiating the heat source while scanning, the heat source irradiated to the end portion on the joining side of the first metal member has a central portion and a peripheral portion located at a periphery of the central portion and having energy intensity lower than that of the central portion, and in the peripheral portion, a length in a scanning direction of the heat source is longer than a length in a direction perpendicular or substantially perpendicular to the scanning direction of the heat source.

摘要： A vehicle body upper structure includes: roof side rails; side outer panels; and a roof panel made of a material different from a martial of the roof side rails. The roof panel and the paired left and right side outer panels are fixed to one another by braze joining. An end portion of the roof panel in a vehicle front-rear direction includes a first coupling portion in which one of the roof side rails, the roof panel, and one of the side outer panels are coupled to one another, a notch portion that is provided on the inner side in the vehicle width direction of the first coupling portion, and a fragile portion that extends from a tip end portion of the notch portion toward a braze joining portion of the side outer panel and the roof panel.

摘要： A vehicle body upper structure includes: roof side rails provided at end portions in a vehicle width direction of a vehicle body upper portion; side outer panels covering vehicle outer side surfaces of the roof side rails; and a roof panel made of a material different from a martial of the roof side rails and provided at a center portion in the vehicle width direction of the vehicle body upper portion, and the roof panel and the paired side outer panels are fixed to one another by braze joining. Outer end portions in the vehicle width direction of the side outer panels are joined to outer end portions in the vehicle width direction of the roof side rails. Inner end portions in the vehicle width direction of the side outer panels are not joined to inner end portions in the vehicle width direction of the roof side rails.

摘要： A bonding structure includes a flange bonding portion formed by bonding flanges of a front pillar inner member made of iron and of a front pillar stiffener made of iron to each other, and a dissimilar material bonding portion formed by bonding the front pillar stiffener to a front pillar outer member being an aluminum external plate. The dissimilar material bonding portion is disposed at an adjacent wall located away from the flange bonding portion of the front pillar stiffener and the front pillar inner member.
