CS241831B1 - Device for prestressing the guide groove of welding machines - Google Patents

Abstract

The device for prestressing the guide groove of automatic welding machines when welding vertical, inclined walls and ceilings made of stainless steel or other materials using prestressing is characterized by the fact that the guide groove for attaching the automatic welding machine is anchored at its upper or lower end. An arm is attached to the unanchored part to capture the reaction from the device for extracting the force required for prestressing the guide groove. The arm is also attached to the terminated support and a control device for checking the prestressing is placed between the device for extracting the force required for prestressing the guide groove and the arm. The method of welding using a prestressed groove can be used in mechanical engineering, construction, the chemical industry and especially in the atomic program.

Description

The device for prestressing the guide groove of welding machines during the welding of vertical, inclined walls and ceilings of stainless steel or other materials by means of prestressing is characterized in that the guide groove for gripping the welding machine is anchored by its upper or lower end. An arm is attached to the non-anchored portion to receive the reaction from the device for exerting the force necessary to bias the guide groove. The arm is also attached to the anchored support, and a preload control device is located between the force exerting force required to bias the guide groove and the arm.

The preloaded welding process can be used in engineering, construction, chemical industry and especially in the atomic program.

BACKGROUND OF THE INVENTION The present invention relates to a device for prestressing a guide groove of a welding machine using a weldment to weld vertical, sloping walls and ceilings by prestressing.

According to the state of the art, the guide grooves for hanging and running the welding machines are stitched to the weldment. When welding stainless steel or weldments of other material for use in the nuclear and other industries, the existing guide grooves cannot be used as they would have to be welded, which is usually prohibited because of the difficulty and in most cases impossibility of inspecting weld stitches the risk that the stitch may impair the weakness of the welded base material.

The above-mentioned disadvantages are eliminated by the invention, characterized in that the device for prestressing the guide groove of welding machines when welding vertical, inclined walls and ceilings of stainless steel or other materials by prestressing is characterized in that the guide groove for gripping the welding machine is its upper or anchored at the bottom end. An arm for engaging the reaction from the device for exerting the force required to bias the guide groove is attached to the open portion. The arm is attached to the anchored support, and a preload control device is disposed between the force exerting device required to bias the guide groove and the arm.

The advantage of the solution according to the invention is that the productivity of work and the welding of metal sheets, both stainless steel and others, are increased, which would otherwise not be possible. The guide groove and the prestressing device are light in weight and are easy to move for further welding.

An example of the subject matter of the invention is shown in the drawing, where the figure represents a side view.

An example of a device for generating a preload of a guide groove is a structure consisting of a prestressed guide groove 1 which is anchored at the lower or upper part. An arm 3 is attached to the non-anchored part which receives the responses from the device 2 for exerting the force required to bias the guide groove 1. The arm 3 is attached to a support 4 which is anchored to the weldment or other fixed part. A device 5 is provided for checking the preload. A mobile welding machine 6 is mounted on the guide groove 1.

The device for prestressing the guide groove 1 according to the invention operates in such a way that the guide groove 1 and the support 4 are fixed to the weldment or other fixed part. The arm 3 is connected to the support 4 by a groove 1 and transmits the force to the groove from the action of the device 2 for exerting a preload of the guide groove 1.

Said method of welding by automatic welding machines for welding vertical, sloping walls and machines made of stainless steel or other materials can be used, for example, in the nuclear industry, especially in the production of spent fuel storages and storage facilities, in the construction of tanks and the like.
