The present invention relates to a multifunctional welding machine, and more particularly, it is possible to selectively use a torch arm of various functions, to weld various shapes, and to control the strength of the magnetic force through the height adjustment in the moving cart. The present invention relates to a multifunctional welding machine that brings convenience in working by providing a magnetic block.

Welding is the only means of joining members in shipbuilding at this time, and is an important part that occupies a large proportion (generally about 40 to 60% of the total construction) not only in block assembly work but also in mounting work.

Although welding of irregularly shaped members is sometimes performed during the welding work for drying the hull, in general, welding of a certain type of members such as an H-beam or an I-beam is performed. At this time, in the case of welding the shape of the predetermined form, a dedicated welding machine is used for fast and accurate work.

However, conventional welders are subdivided into welders for seam welding, welders for fillet welding, welders for fillet welding and welders for gunnel welding according to the shape of the members. I had to use another dedicated welder.

This caused a delay in ship construction time, lowered the efficiency of ship production, and consequently acted as a major problem to reduce ship competitiveness.

Accordingly, in the present invention, in order to overcome the problems of the prior art as described above, butt welding, upper welding, fillet welding, and keyhole welding can be performed using one welding machine. It is a technical challenge to provide a multifunctional welder.

In order to achieve the above technical problem, according to the present invention includes a mobile bogie, a welding torch installed by a clamp to perform welding, and a welding running controller for controlling welding of the welding torch or traveling of the mobile bogie. A multifunctional welding machine comprising: a torch arm having the clamp as any one selected from a fixed type, a left and right weaving type, and a top and bottom weaving type, which are detachable from the moving cart; Weaving controller for controlling the weaving motion of the torch arm attached to the welding running controller (Add-on) or connected independently when using the torch arm of the left and right weaving type, the upper and lower weaving type; A magnetic block mounted to move up and down in the moving cart to adjust the strength of the magnetic force of the bottom of the moving cart; And an inching switch provided on the welding running controller and responsible for supplying the non-plating wire.

At this time, the magnetic block is fixed to the lower end of the support coupled to the transport lever of the mobile cart, by inserting a fixing pin on the pin hole of the support pulled out over the upper surface of the mobile cart by an upward pull operation of the transport lever, It is preferable that the height is adjusted. Here, the height adjustment of the magnetic block is related to the magnetic strength of the bottom portion of the mobile trolley in which the magnetic block is to be built. For example, when the magnetic fillet welding is performed, the magnetic block may be fixed after lifting, thereby weakening the magnetic force of the bottom surface of the moving cart.

And the weaving controller includes a one-side stop control switch for controlling one stop time of the torch arm during weaving; Another stop control switch for controlling the other stop time of the torch arm during weaving; Weaving width control switch for adjusting the weaving width of the torch arm; It is preferable to include a weaving speed control switch for adjusting the weaving speed of the torch arm and a weaving shape control switch for adjusting the weaving shape of the torch arm. It is possible to control various weaving operations of the welding torch installed in the torch arm selected by the weaving controller to perform welding.

Hereinafter, a preferred embodiment of the multifunctional welding machine according to the present invention will be described.

The welding driving controller 40 may further include an inching switch.

Here, the inching switch is a switch that is responsible for supplying the non-plated wire, and preferably in the form of a push button switch. By operating the inching switch, it is possible to more easily adjust the initial set length of the wire required before the start of welding.

Although the conveying lever 50 is commonly seen in a conventional welding machine, the conveying lever 50 in this embodiment is not provided for the purpose of providing only convenience of conveying, unlike a conventional welding machine. The transport lever 50 plays a part in association with the magnetic strength control of the magnetic block to be described later.
