In the welding/cutting device (30), the welding is flat welding.

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

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

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

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

Accordingly, a welding stated suitable for spot welding and laser welding is obtained, and sufficient welding quality can be ensured in both spot welding and laser welding.

The invention relates generally to welding and, more specifically, to welding wires for arc welding, such as Gas Metal Arc Welding (GMAW) or Flux Core Arc Welding (FCAW).

The welding is effected using an ultrasonic welding method.

The method includes welding a cardiotomy filter (40) to a filter frame (36) using radio frequency welding, using hot plate welding or using vibration welding.

One preferred welding technique is vibration welding.

The weld environment mechanism orbits the first tubing and second tubing during the orbitally welding.

The invention relates generally to welding and, more specifically, to welding wires for arc welding, such as Gas Metal Arc Welding (GMAW) or Flux Core Arc Welding (FCAW).

A system and method for welding combining plasma welding and MIG (Metal-Inert-Gas) welding.

While moving the welding torch (2) along a taught welding line, welding is carried out.

A resistance welding or a laser welding with less thermal effect is desirably used for the welding.
