Feature Spotlights - Smooth Robotics

Feature Spotlight: Stitch

Stitch welding is a technique where a series of short welds are spaced out with deliberate gaps—for example, 3 cm of weld followed by 3 cm of air. This method reduces heat input into the workpiece, helping to minimize distortion and shrinkage, while also decreasing the size of the Heat Affected Zone (HAZ).

Feature Spotlight: Surfacing

The Surfacing feature in SmoothTool is designed to automate one of the most physically demanding and repetitive welding tasks: cladding and hardfacing. Whether you’re applying a corrosion-resistant layer or building up worn parts to extend their life, Surfacing helps you program these complex welding patterns with ease—directly from the teach pendant.

Feature Spotlight: Weaving

Weaving in SmoothTool allows you to apply dynamic side-to-side motion to your welds, creating stronger, wider, and more consistent beads—especially useful for filling gaps or improving weld penetration. With just one click, you can apply weaving to your entire weld or fine-tune it for specific segments of the weld path.

Everything between the joint and the finished weld

SmoothTool covers teaching and visualisation, weld path and geometry, control and consistency, and reach. Each feature has its own page with parameters and examples. Available features depend on PolyScope version and licence, and your partner confirms the configuration for your welding solution.

Teaching and Visualisation



3D Universe

See the arm, the torch and the full weld path on screen before an arc strikes, and touch up any point.



Touch Sense

Locate the actual position of the part and shift the path to match, so a part that is not exactly where it was last time still welds correctly.

*Option on SmoothTool X

Weld Path and Geometry



Weaving

Weaving patterns on linear and circular paths, configurable to joint geometry and material.



Multipass

Build up a multi-pass weld from a single taught path instead of teaching each pass.

*Option on SmoothTool X



Stitching

Set stitch parameters directly for distortion control and material savings.



Tacking

Consistent parameterised tacks before the full pass.



Offset

Copy a taught weld and offset it in any direction or rotation, for repeated features on the same part.

*Option on SmoothTool X



Surfacing

Hardfacing and cladding passes for wear surfaces and repair work.

*Option on SmoothTool X

Pipe Welding

Full-circumference welds around a pipe, including positions that are impractical by hand.

Control and Consistency



Angle System

Type in work and travel angles and have them applied the same way across the whole program.



Profile System

Save welding parameters as profiles and reuse them across parts, operators and shifts.



Seam Tracking

Through-the-arc tracking adjusts the path during the weld. Available with selected power sources.

*Option on SmoothTool X

Reach



External Axis*

Add a rotary positioner or a linear rail and control it from the same program. The Proarc PT-200 positioner is plug and play. Other positioners and rails are integrated by your partner through the SmoothTool interface.
