Definitions
- the invention relates to a method for welding workpieces with the supply of heat by means of or via a welding device, workpieces or workpiece parts being arranged with a gap to one another and welded to one another at this gap, and a relative movement between the workpiece and the welding device being provided
- the invention further relates to a device for welding with the supply of heat, comprising a welding device which generates the heat required for the welding process, for welding workpieces or workpiece parts arranged with a gap to one another, and means for generating a relative movement between the workpiece and the welding device
- the gap width may be a maximum of a few hundredths of a millimeter.
- the required clamping technology is particularly complex in terms of equipment. Cooling, for example, one
- German patent DE 43 15 605 C2 which also deals with the problem of welding distortion, it is proposed to introduce an evaporation-resistant lubricant, for example graphite, into the welding gap before welding.
- an evaporation-resistant lubricant for example graphite
- the invention is therefore based on the object of demonstrating a method and a device of the type mentioned at the outset with which the problems existing due to the heat distortion can be effectively countered.
- it should be possible to set the gap width in the welding process also during the welding process can
- an arrangement of the workpieces or workpiece parts with a gap (welding gap) to one another is provided.
- the values of the gap widths can be very small in the context of the invention and, in the limit case with a frictional arrangement, can also approach zero
- the additional heat supply is spatially limited at a distance from the welding point. This increases the divisibility of the gap width in the welding process and also ensures that the welding process is not disturbed or hindered by the additional heat supply
- the additional heat supply is spatially related to a point to be welded in such a way that welding of the workpieces or workpieces takes place temporally after the heating due to the additional heat supply. This means that - considered stationary - the additional heat is first supplied and then under by the additional heat supply of narrow gap width welding of the workpieces or workpieces takes place
- At least one heat source is used on both sides of the welding gap for the additional supply of heat. This measure makes the setting of the gap width considerably easier
- the invention offers wide variation possibilities for adaptation to special conditions.
- the additional heat supply according to the invention can in particular be adapted to the welding parameters of the welding process and / or to the workpieces or workpieces to be welded, in particular to the type of
- the additionally supplied heat can be generated by any suitable means.
- the additional heat can be supplied by means of flames or, preferably, by means of laser radiation.
- the additionally supplied heat can be carried by burners or, preferably, lasers, in particular diode lasers
- the invention can be used in connection with all welding processes. It can be used in particular when welding thin materials.
- the advantages associated with the invention are particularly evident in laser welding
- the additional heat can be supplied with respect to the arrangement of the welding device on the same and / or on the opposite side. If the welding device - for example a laser welding head - is arranged above the workpieces or parts to be welded, the heat sources for additional heat supply can be above and / or below the workpieces or parts are arranged
- the workpiece material is heated and expands.
- the welding gap is preferably reduced to the desired width. Good results could be achieved if the material is heated in the area a few centimeters before the welding point advantageously at a distance from the welding point of less than 5 cm, preferably between 0.5 and 3 cm
- the invention can be used in connection with automated welding processes.
- the advantages achieved with the invention are particularly great if the additional heat supply is regulated and / or controlled during welding, ie means for regulating or controlling the additional heat supply are present.
- the welding gap be measured online and set to desired values via a change in power (change in the additional heat generated) - for example by changing the power of two diode lasers used on each side of the welding gap
