Basic description

  • GWU BUILDER XXL Mk.I is sophisticated industrial production unit for circumferential and longitudinal welding of high capacity tanks with maximal diameter of 5000mm.  Lenght can reach 25000mm. Weight of welded product is depended on the choice of roller positioners or assembling line
  • Mechanical construction of the machine is spacial and consists of two massive towers (GANTRY). Bases of both towers are a bit wider and therefore are stable and used as a platform for placing the generators up to 500Kgs. Right tower is equipped with ergonomic place for the operator which is protected against the fall of welded part by special frame. The whole system of both towers is movable along the rails, synchronized motors with maximal speed of 4,0m/min are used. Between both towers there is heighly adjustable portal of aluminium construction by which one or two torch heads are carried.

  • Torch heads are precise set for the mechanical point of view by which micromovement axises X and Z are integrated and in case of MAG method also the pendel unit. Both axises (X+Z) can be moved in the range of +/- 150mm in each direction, pendel unit 20mm for each side. Considering the fact which welding technology is used another suitable options are added to basic configuration. Feeders and coils of the wire are integral part of the support as well as the systems of recycling and adding the flux.

  • GANTRY BUILDER can be connected with roller positioners CARRIER and build sophisticated production complex of the highest technological level.

  • On the system digital industrial camera IRIS NICK can be mounted by which the focused shot of the place where is the welding performed is taken. This camera is suitable for any method of welding, including MAG PULSE method, and quarantees great results. Another camera is recording the whole working place from the top and enables the operator to find the most optimal welding position.

  • Control system is based on industrial computer (Windows platform) by which the visualization of advanced user interface HST CREATIVE is arranged and seen on 19“ display equipped with reliable Touch screen technology with glass surface. Controlling of modes by touchscreen, proportional digital joystick, context offer, use of touch commands, digital system of automatic control of welding position by touch sonde.


... Machine is suitable for working in heavy industry, especially by welding of tanks of different types in the mode of 7/24. The whole unit is suitable for welding pressure and non-pressure high capacity tanks. Wide range of options and advanced digital technologies which are easy to operate for SAW, MAG, TIG, PLASMA WELD methods of welding and KEY HOLE proces.


Benefits of product

√  Sturdy construction of two towers without material flickers brought into the process of welding, mechanical defects of welding are eliminated

 √  Small dimensions of floor projection because of the compact solution of construction and small requirements for the space on the workshop

 √   Possibility of two technologies at the same time (for example MAG + SAW)

   Movement of the machine along the rails that means that the unit changes its position for longitudinal welding

 √  Micro movement axises without pressure with accuracy of positioning of 0,2mm, technical parameters of welding displayed on the display

 √  Precise positioning of 0,1mm by the operator by proportional joystick or system of controlling the welding position by touch sonde

√   High – tech industrial computer system of welding process controlling through the touchscreen display and controlling by commands

√   Recording of welding process by digital camera which is complemented by another camera placed above working place

   Safety stand of operator in covered moveable working station


Technical parameters




Necessary choice

Neccesary to be added to the machine. If you have any questions do not hesitate to contact us. Your offer can be successfully finished without these options.

Constructional surcharge

These options must be added to the machine during the production process. Later it can be connected with high costs or it is fully impossible.

Free options

These options can be mounted anytime. Later order of these options does not mean higher costs.
