Description

In ocHOBHOiM auth. St. LG9 60938 describes a method for semi-automatic electric arc welding using a device consisting of a guide along which the holder can move along the electrode as the electrode melts. This method provides for the possibility of welding at any angle with any inclination of the guide and with simultaneous operation of several welding devices. However, it does not provide automatic ignition of the arc on each successive electrode when the previously operated is fully melted.

The proposed described method eliminates this drawback, thereby achieving automation of the welding process when working with several devices. For this purpose, the electrodes are arranged one after the other along the seam and set so that when the first order of electrode operation is melted, the arc automatically passes to the end of the second electrode without interrupting the welding process. In this case, all electrodes are connected to the source of welding current in parallel.

The drawing shows a sketch of the installation of welding devices during electric welding according to the proposed method.

Holders / electrodes 2 are mounted in guides 3, the angle of inclination of which can be changed with the help of joint 4, in order to control the welding speed. A hinge 5 is provided to position the electrode across the bore, and an electromagnet 6 is attached to secure the guide 3 to the product to be welded. All electrodes are connected in parallel to the source of welding current.

The guides 3 with the electrodes 2 are positioned along the welding joint one by one. After the first order of the electrode melts, which during the welding process moves along the guide 3, the arc automatically moves to the next electrode, which is installed in the place where the welding process ends with the first electrode.
