Description

Guide-rail device for guiding welding direction

The present invention relates to a guide rail device for welding, and relates to a welding guide rail device that allows the welding device to weld the welded portion of the welding base material accurately when butt welding.

In general, welding is a joining method in which metal materials are joined metallurgically by heating, pressing, or the like. Welding can be classified metallurgically into fusion welding, pressure welding and soldering. Fusion welding is also called melt welding, and is a method of locally heating and melting a joining portion of a base metal to be joined, fusing them together, and joining them by a local casting action. Pressure welding, also called pressure welding, is a method of heating a joint to an appropriate temperature to apply mechanical pressure thereto to complete the joint. Lead welding is a method of achieving a bonding purpose by melting and adding a nonferrous alloy filler material, that is, a solder material having a much lower melting point than a base metal to be joined to the joint, by utilizing intermolecular attraction during solidification of the molten lead material.

Gas welding is the most commonly used method of the above-mentioned welding or melting welding. The gas welding method is a welding method using high heat generated during the reaction between various heating gases and oxygen, that is, gas combustion heat as a welding heat source.The gas welding method is performed by blasting and burning a mixed gas of heating gas and oxygen from the end of the welding torch. This gas heat is used as a heat source for welding.

The apparatus used for gas welding consists of an oxygen storage tank, a gas storage tank, a connecting hose extending from each tank, and a torch connected to each connecting hose. The torch consists of a handle part, a mixing chamber in which oxygen and gas supplied through the connecting hose are mixed, and a crater for ejecting the mixed gas mixed in the mixing chamber to the outside. The handle portion is provided with a flow control valve for controlling the amount of oxygen and gas flowing into the mixing chamber from each storage tank.

Therefore, when the worker performs the welding operation, the flow control valve is opened to inject the mixed gas to the outside of the crater, and then a spark is generated using a lighter in the crater to generate a gas flame. When the worker stops the welding work, close the flow control valve so that oxygen and gas do not flow into the welding torch, so that no gas flame is generated in the crater. Then, when the worker resumes the welding operation, the flow control valve is opened again and the lighter is turned on to generate a gas flame.

On the other hand, the welding method is a method in which a person grips the welding machine to weld the welding base material manually. In this manual welding method, there is a concern that the welding reliability is lowered because the work efficiency depends entirely on the skill of the operator. In addition, in fillet welding, in which both base metals are orthogonally arranged and welded to join the contact portions, it is difficult for a worker to perform a welding operation, resulting in a high efficiency and a long working time. The disadvantage is that it takes.

In order to overcome these disadvantages, an automatic welding traveling device has recently been developed. The automatic welding traveling device has a structure in which a welding torch is mounted on a wheeled body.

1 is a side view showing a state in which the fillet welding using a general automatic welding traveling device. As shown in this figure, the traveling device is placed at a point adjacent to the welded portion of the first base material 1 placed in the horizontal direction and the second base material 2 installed orthogonally to the first base material 1 to fillet welding. It is placed in the standby state.

The structure of the traveling device is attached to the driving wheel 12 and the bottom of the body portion 10 which are provided at four bottom surfaces of the plate-shaped body portion 10 and the body portion 10, so that the traveling device is firstly driven. Welding toe for welding the welding site between the first base material (1) and the second base material (2) is installed on the mounting electromagnet (not shown) and the body portion 10 to prevent the separation from the base material (1) It consists of the ochi 11 etc.

The driving wheel 12 is driven by a driving force by a driving motor (not shown) installed in the upper portion of the body portion 10 so as to drive the body portion 10.

The welding torch 11 is attached to the support member 13 provided on the body portion 10, and the lower end portion thereof is inclined downward to be welded.

With this configuration, when the first base material 1 and the second base material 2 are to be mutually fillet welded, power is supplied to the drive motor so that the welding traveling device travels along the welding portion, and at the same time By letting the torch 11 radiate a welding spark, the welding part of the 1st base material 1 and the 2nd base material 2 is welded. Thus, by the fillet welding of the first base material 1 and the second base material 2, the fillet structure can be completed.

By the way, the above-mentioned fillet welding is usually performed by a forward welding method. Therefore, the traveling device welds the welding portion while advancing along the welding portion.

In this case, in order for the traveling device to perform an accurate welding operation, the welding torch 11 must be accurately positioned at the welding portion even when the traveling device travels. In the fillet welding, since the traveling device is driven while being guided by the second base material 2 placed on the plate of the first base material 1 and standing in the vertical direction, a relatively accurate welding operation can be performed.

By the way, when the butt welding is performed in the state where the welding base materials are butted together, since the plate surfaces of both welding base materials are flat, there is no portion to which the traveling device is to be guided.

Therefore, the traveling device is not guided, there is a problem that the work efficiency of welding is lowered. Not only automatic welding using a traveling device but also manual butt welding, if a separate guide device is not provided, welding workability deteriorates.

Accordingly, an object of the present invention is to provide a welding guide rail device that can be accurately welded to the welding portion of the welding base material when the butt welding device is devised to solve the above problems.
