Description

H. Van Bergen

The invention relates to a device for automatic inert gas welding of metal pipe segments, specifically for joining the same at a certain angle to each other and only for metal pipes with a preferably rectangular or square profile.

Inert gas welding equipment for mechanized welding is not known Welding of profiles with a rectangular and / or square cross-section, with the pipe segments to be joined via a SchnellspannvurriüiiüTig be positioned at a predetermined angle can. Likewise, it is not known that two burners on both sides of the pipe segments to be welded are via a pneumatic control device can be proceeded. In contrast, it is known that especially the releasable clamping of profiles with different cross-sections and shape can be done using a quick release device where the |

The workpiece is clamped by means of an eccentric device. Inert gas welding systems are also known where the torch from |

Hand-operated or in larger systems where the burner is moved by machine. The former are in certain fields of application uneconomical and also sometimes lead to considerable damage to health, such as flashing of the eyes or the so-called iron dust I lung, known as siderosis. For the continuous I joining of pipe segments, which are to be connected to one another by welding in a certain selectable angle range, are mechanized Attachments not known.

The invention is based on the object of a structurally simple Protected gas welding equipment built up and meeting the requirements of economic efficiency and the humanization of the workplace - without manual guidance of the burners and without manual positioning of those to be welded to one another in a certain winekl Pipe segments - to create.

The disadvantages of the prior art are to be eliminated.

The object is achieved according to the invention in that two manually adjustable eccentric devices, which is an optional adjustment within a given angular range And to allow adjustment to the desired setting angle, are arranged and above the eccentric a traverse is attached to the base plate. At this traverse, however, are in a certain adjustable distance to guide and to move the torch two lifting cylinders with torch holding head appropriate. The burner head itself is designed so that an exact positioning of the burner accordingly the respective pipe cross-section is given after loosening the clamping screws.

Furthermore, the mechanized inert gas welding device is enclosed by means of a hood construction in such a way that Flashing of the eyes and / or exposure to UV and IR rays is prevented, i.e. the sweating process is initiated only after the hood is closed.

Overall, the invention creates a mechanized shielding gas welding device that meets the requirements for economy, increased security and Hutianization of the workplace is largely fair.
