DETAILED DESCRIPTION

[0028] FIG. 1a shows a device 1 for welding in an orbital welding process by means of welding gas in an arc welding process, comprising a receiving region 2 into which a tubular round object to be welded can be inserted, wherein the receiving region 2 is constructed in particular in two parts with a folding joint means 5 for folding up a closing region 3, a welding means 6 which rotates around the receiving region 2 and through which the weldable, tubular round object can be welded in a rounding by means of arc welding methods, wherein a positive pole means comprises two surrounding outer plate means 7.

[0029] In particular metal, in particular aluminum side parts, in particular aluminum clamping-shell housings, and a negative pole means is arranged on the receiving region 2 with the rotating welding means, wherein an electrically insulating, heat stable insulating means body 4 is arranged in each case between negative pole means and positive pole means, wherein a 3D printed region is integrated by an 3D printing, in particular with one or more line means 8 for welding gas and/or one or more line means 9 for cooling water, in particular with one or more line means 8 for welding gas and/or one or more line means 9 for cooling water, in particular the insulating means body 4 is formed predominantly, in particular substantially completely, by 3D-printing. Two insulating body parts 4 are inserted exemplarily, they can be constructed in an advantageous and in a simple manner in different ways, as shown by way of example in FIGS. 1b, c, 2a-c.

[0030] FIG. 1b shows an insulating means body 4, produced by the 3D-printing method, can be inserted into an orbital welding tong, as shown in FIG. 1, with a receiving region 2 and, for example, with one or more line means 9 for cooling water, which can be partially recognised, which extend into end regions 12 of the line means, wherein line means 9 for cooling water are integrated into the insulating means body 4 as far as to end regions 10 of the receiving region 2, in particular up to a corresponding height of a folding joint means 5 up to correspondingly outer plate means 7 shown in FIG. 1.

[0031] FIG. 1c shows an insulating means body 4, the region of the sectional illustration, which is shown in FIG. 1b, being shown here in an opened sectional view. An exemplary line means 9 cools a body region 16 and another exemplary end portion 10.

[0032] FIG. 2a shows an insulating means body, produced in 3D-printing, having a plurality of functional planes 13 which merge homogeneously, essentially in one piece, into one another, into which line means 8, 9 can be integrated one above the other and/or next to one another and thus can operate in a multifunctional manner and at the same time reliably up to the end regions 10, 12. Line means 8 for welding gas extend up to end regions 12 of the receiving region 2, in particular up to gas outlets 11 in the receiving region 2, in particular for welding gas in the form of argon for arc activation. Line means 8 for welding gas and/or line means 9 for cooling water can thus be arranged securely and in a simple manner in a plane or a plurality of planes 13 one above the other in the insulating means body 4.

[0033] Furthermore, as shown by way of example, in particular for avoiding different expansion lengths in the case of temperature loading and for a considerable saving of space, actuating means 14 can be formed in particular for the welding means, in particular mechanical drive means, in particular gear wheels and/or journal means 15 for gearwheels and/or bearings for gearwheels, in particular ball bearings, into the insulating means body 4.

[0034] FIG. 2b shows an insulating means body 4 shown opened with a plurality of functional planes 13′, 13″, 13′″, which can represent a further exemplary functional plane 13 on an insulating means body 4, as shown by way of example in FIG. 2a.

[0035] FIG. 2c shows an insulating means body 4 having a plurality of functional planes 13′, 13″, 13′″, for example on a lower functional plane 13′, such as, for example, in FIG. 2a and a subsequent plane 13′ shown here further closed, as shown in FIG. 2b. As a result of the planes, a variety of functions can be integrated into the insulating body, which are at the same time secure and are designed as far as outer regions, so that, for example, no cold bridges can be formed on sensitive mechanical elements.
