摘要： Disclosed is a friction stir welding method for welding two members (4, 5) to be welded which differ in physical properties and/or mechanical properties by abutting the two members to each other, inserting a pin portion (2) of a rotary tool (1) having the pin portion and a shoulder portion (3) to the abutment surfaces of the two members (4, 5), and moving the rotary tool (1) along the abutment surfaces. The pin portion (2) is inserted to only one of the members (4), the pin portion is not inserted to the other of the members (5) but only the shoulder portion (3) is set in contact with the other of the members, and, while this condition is maintained, the rotary tool (1) is moved. With this method, only the member on the side where the pin is inserted can be made to undergo plastic flow attendant on a friction stir action. The metal in plastic flow is pressed against the opposite member at an elevated temperature and high pressure, whereby diffusion of atoms is caused in the vicinity of the abutment surfaces, and the members are welded.

摘要： In the welding of aluminium alloy structural components, e.g. in the aerospace industry, one of the welded components is a sheet product (1) having a core (2) and a clad layer (3) of filler material. During welding, the clad layer (3) provides filler for the welding pool, and the core (2) remains substantially unmelted. Consequently adhesion between the core and the clad layer maintains its strength, e.g. keeps at least 80 % of its pre-welding strength.

摘要： In an area where an Al alloy plate and a steel plate lap each other, a circular blank of steel plate is made to lap the Al alloy plate, and these three members are compressed by a pair of electrodes while a welding current is passed between the both electrodes. Thus melting of a current passing portion of the Al alloy plate and a neighborhood thereof, removal of the melted portion due to partial expanding deformation of the blank toward the Al alloy plate, abutting of the expanding deformed portion against the steel plate and resistance welding of the expanding deformed portion with the steel plate are successively carried out.

摘要： The diffusion bonding of aluminium and aluminium alloys presents problems because , when left exposed to the atmosphere even for a short time, they acquire an extremely tenacious surface oxide layer that inhibits or prevents satisfactory diffusion bonding. Unlike titanium, this oxide layer is not absorbed at diffusion bonding temperatures. The present invention comprises a method of reducing oxidation of a surface of aluminium or aluminium alloy (10) by causing a nitride film to form on the surface. This film is believed to prevent oxidation of the aluminium or aluminium alloy, but to be absorbable into it at diffusion bonding temperatures. The nitride film is applied to the piece of aluminium or aluminium alloy (10) in a vacuum chamber (4) by sputtering with nitrogen ions, or by heating the piece (10) in a nitrogen gas atmosphere.
