Abstract: The method for connecting thin-walled casings by fusion welding comprises the following: preparation of the end faces to be connected of the casings, abutting arrangement on centring devices and common melting of the end faces to be connected while an arrangement gap sufficient for carrying out the welding is temporarily maintained between the surfaces lying against one another of the end faces.  On each of the casings to be connected, deforming of the micro-projections on the surface to be welded of the end faces is carried out by plastic deformation along with upsetting of the material.  On the end face, the metal to be deformed is moved to the side of the inner surface of the casing and an inner, annular bead strip is formed thereupon.  The casings to be connected are arranged in a device that carries out centring with respect to the outer diameter.  Then, initially at the circumference in the plane of the connection, spot welding thereof is carried out.  Subsequently, main welding is carried out right through, thereby forming a fusion zone of a width between 4 d and 6 d, where d is the thickness of the wall of the casing to be welded in mm, and the heat removal in the parts to be welded begins at a distance that does not exceed 8 d from the centre line of the connection.

Abstract: In making a hollow element such as a muffler, an accumulator or the like constituting a refrigerating cycle machine, a cylindrical member is first cut into a predetermined length, and opposite ends of a cut piece are then processed, thereby making a hollow element having opposite ends of a diameter small than a diameter of the cylindrical member. Each of the opposite ends of the hollow element is joined to a connecting pipe while cooling a body and the opposite ends of the hollow element so that a material strength of the hollow element may not be reduced.

Abstract: Disclosed is a friction welding apparatus in which electricity is supplied to a servo motor (15) to rotate a spindle (3) to thereby impart a fixed relative rotational motion to one workpiece (5) and another workpiece (9), and, while doing so, the one workpiece (5) and the other workpiece (9) are brought into contact with each other and imparted a frictional thrust thereto to soften a bonding interface between the two workpieces (5) and (9). After this, the friction welding apparatus undergoes speed reduction until the RPM of the spindle (3) becomes a phase adjustment RPM; when the RPM of the spindle attains the phase adjustment RPM, a clutch device (19) is engaged with the spindle, and the electricity supply to the servo motor (15) is cut off to stop the rotation of the spindle (3).
