Arc Welding with FASTSUITE

Arc Welding made simple and reliable

FASTSUITE simplifies the programming of arc weld operations and provides optimized weld strategies for standard welding operations, specific box welding, stitch or tack welding and multi-layer welding.

Support of various welding methods
Embedded sensor and vision system support
Synchronized programming of multi-robot cells

FASTSUITE Edition 2 generates precise welding programs that include all robot motions and controller commands for a direct program execution on the robot cell. No manual touch-up is required anymore. Even scenarios of two or more robots working on one component simultaneously can be implemented with the software. The 3D simulation twin of the robot cell enables a full supervision of the robots‘ working environment, and collisions as well as robot arm interferences can be detected and avoided already during the programming phase. This leads to high-quality, reliable and repeatable welding results, and an efficient use of the robot equipment with no production stop.

Simple robotic welding jobs as well as complex welding cell layouts with multiple robots and external axes can be easily and efficiently programmed with just one standardized simulation software.

  • Comprehensive libraries are available for building a realistic 3D work cell (robots, turn tables, workpiece positioners, clamping devices, torches, power supplies, vision systems etc.)
  • Flexibility when importing CAD data from any CAD system thru standard interfaces like STEP, IGES and JT. Native interfaces to directly load CATIA, NX, SolidWorks etc. are options.
  • CAD-to-path algorithms for easy weld line definitions directly from 3D CAD data, including automatic approach and retract motions
  • Easy definition and modification of process parameters, such as weld line offsets, gun orientation etc.
  • Pre-defined parameter sets from a customizable database are available to support the correct selection weld parameters for MIG/MAG welding processes
  • Customizable process instructions for weld in it, start and end with full technical parameter setting.
  • Automatic welding torch position in box corners and edges.
  • Fully-synchronized programming of multi-robot cells with dynamic positioners.
  • Dynamic control of workpiece positioners for achieving an optimized (permanently vertical) weld torch orientation along 3D weld lines

Defining precise welding programs with various welding methods is just a matter of a mouse click

  • The Basic Welding method generates a welding cycle from an existing process geometry
    defined by any workpiece edge. The welding cycle consists of 3 stages: approach, process and retract
  • The Box Welding method expands the basic welding cycle. The weld torch orientation is automatically adjusted in corners for collision-free reachability.
  • The Stitch Welding method expands the Basic Welding cycle by automatically producing several seam sections along the selected weld line. There are several linking strategies available to automatically connect these sections to a complete operation.
  • The Multi-Layer Welding method expands the basic welding cycle and produces several weld line layers. The tool path can be generated and edited by different “Recipes”.
  • Seam Tracking, also referred to as Joint Finding, describes the ability to compensate for an offset or position shift in the real workpiece, compared to the theoretical CAD part. 
  • Alternatively, the welding wire or weld torch nozzle can function as a sensor for Touch-up sensing. An ‘ideal’ contact point is used as reference and the ‘actual workpiece’ is found by contact. The difference is calculated and stored in a variable which can later be used as offset in programs.
  • As soon as the robot cell is equipped with a dynamic workpiece positioner, the so-called Downhand welding strategy is available with all welding methods to enable an automatic part orientation in relation to a vertical weld torch position.
