Welding automat HAMMER
MACHINE VARIANTS
Purpose of machine is to work in industry, even with high hourly load. The single-purpose concept of the machine brings the ultimative solution for the production of open vessels and tanks. The machine performs circumferential welds only so that the shells and bottoms are established and immediately afterwards are welded in highly productive by the TIG or PLASMA WELD method. Most of the applications are successful without prior of spot welding the shell and bottom. In exceptional cases the machine can automatically perform spot welding of shell and bottom and then the welding itself is done. The machine welds on copper pad which is the part of automatic clamping tool inserted from the innert side of welůded product, this clamping tool integrates also the protective gas system for root of the weld protection. RCS 06 control system brings perfect functions for the full automation of this production process.
This is a special solution which is provided only as custom made. Due to the complexity of the whole system and its parts very thorough consultation of requirements is always necessary. The final technical solution and possible feasibility of the project is provided as special project solution and always exactly based to the parameters of the required products, specific applications or the customer production program.

HAMMER SINGLE is special device designed for welding medium-sized open vessels and tanks up to diameter of 1200mm and lengths up to 3500mm. The spatially designed self-supporting mechanical construction of the highest quality is designed for high loads. The machine is equipped with central carrier of pneumatic clamping tool on the left spindle which also integrates divorcing of forming gas under the weld. The clamping tool is mounted on spindle flange that is located in the left machine tower. The left tower is longitudinally movable along precise linear lining by pneumatic cylinder. The right spindle flange carries pressing tool ensures perfect fit of the bottom to the shell. In addition the right tower is equipped with vertically movable pressing head which provides that just-welded part of the bottom with the shell is pressed onto the copper pads of the clamping tool. Also the right tower is longitudinally movable along precise linear lining by pneumatic cylinder.
-
Main rotation drive is solved as backlash-free. Stepper motor spins precise planetary gearbox with toothed belt.
-
Pressing head of the right tower has hydraulically solved basic stroke allowing adjustment for different vessels diameters. The working pressure itself is realized by high-performance tandem pneumatic cylinders which transmit the force to the pressure wheels made of CuCrZr alloy. The welding torch carrier is equipped with oscillating function as independent axis.
-
Essential part of machine is set of clamping tools carry the welded shell and bottom which can be either flat or arched. The clamping tool allows welding different lengths of the shell with one specific type of bottom so the length of the vessel can be variable. On the contrary the vessel diameter have to be always the same for one set of clamping tools. However the changing of clamping tools for different vessel diameters is very easy and takes only few minutes thanks to the central connections of the clamping tools and central carrier.
-
Welding automat can be equipped with a cold wire feeder HST CREATIVE CW 09. The cold wire feeder is fully controlled by the RCS06 control system welding automat and brings to the operator the maximum possibilities of setting of the feeding parameters including the reversation of the feeding of the wire.
-
Significant simplification for the operator can be the equipment of the automat with special digital Remote Control Mighty Controller which increases the flexibility and variability above the basic configuration.
-
Automat is controlled by the excellent control system RCS 06 which provides all conceivable functions for circumferential welding, including accelerations and decelerations of rotary movement, control of the welding source with separate programming and advanced functions of regulation of welding power. The possibility of saving programs and creating program compilations underline the sophistication of the control system.

WELDED PARTS
- The machine is a universal and sophisticated production unit with the ability to weld any of the industrial production within the dimensional and weight limits of the machine. It is possible to perform rotary circumferential welds, fillet welds in the PA / PB position thanks to the tilting tailstock (only in the case of some of the machines) and it is also possible to perform full-fledged longitudinal welds (only the machines with controlled X axis).
- Typical is the production of pressure and non-pressure tanks from all materials with all of the methods of arc welding with the exception of the SAW method. Thanks to the high overall accuracy the machine enables welding of machine parts, flanges, shafts, heat exchangers, tube sheets.
- The machine is able to work in a layered screw welding mode (only the some machines) on the surface of the cylinder and also on the surface of the plate by the spiral layered welding tilted to the 90° (only the machines equipped with the tilting tailstock). Spiral layered welding has interpolated rotation and torch movement - change spindle rotation speed depending on the current diameter. The special software also provides the possibility of welding individual layers of layered welds (it uses a controlled Z axis of the torch stroke). It is also possible to equip the machine with the controlled preheating system of the welded part with digital surface temperature measurement.
TIPS FOR BETTER USE
- An excellent addition is the sophisticated Mighty Controler remote control. It is a freely programmable device by which is possible to control all of the necessary machine functions directly during the welding.
- The control system of the machine is well developed, it provides on-line information about the current rotation speed and the current progress speed. Operating is done using the standard multi-layer MENU.
- Software compilations provide perfect possibilities for fully automated production composite of many different welds.
- Double Torch versions does not restrict the users in the production of technologically complex products and aplications. One method can be used for welding of the root of the weld, another one can be used for the covering layers.
- The tilting tailstock significantly expands the usability of the machine by position welding at angles of 0 - 90°.
- Digital cold wire feeders provide precise welding results in the widest range of applications.
