A tin paste and heat press soldering method for using same.

The welding may include: spin welding, hot plate welding, vibration welding, and ultrasonic welding.

combined spot or projection welding and press-forming machine

The welded joints (16) may be formed by at least one of: spin welding, hot plate welding, laser welding, vibration welding, and ultrasonic welding.

The permanent connections (26; 126) are obtained by means of clinching, spot welding, projection welding, laser welding or gluing.

Suitable welding methods are projection welding, capacitor discharge welding and friction welding.

The welding method employs laser beam welding, electron beam welding or plasma arc welding.

This bond may be achieved by means of friction welding, electron bombardment welding, arc welding, shrink ring fitting, force fitting or caulking.

Effective examples of solid phase welding of this case are solid phase diffusion welding, explosion welding and friction welding.

The seams or pleats are formed by thermal bonding, or ultrasonic welding, or laser welding, or adhesive bonding, or sewing.

The welding unit comprises a friction stir welding head (13) and a fusion welding head (14).

The welding (5) is a continuous or partial one, including a spot welding as well.

The welding is effected using an ultrasonic welding method.

The sleeve is welded onto the hole by way of laser welding or CD welding.
