With BOCHU / CypWeld
BOCHU control.
TitanWeld engineering.
A practical technical partnership for model-led robotic welding, reverse modelling and measured seam work.
A named working relationship
Technical support that stays close to the workpiece.
TitanWeld partners with BOCHU to bring model-led robotic welding into the workshop. All TitanWeld engineers have received training at BOCHU, and TitanWeld receives direct technical support from BOCHU's official team.
Direct technical support
Integration questions can be connected with BOCHU control and vision specialists when the project requires their input.
Project-specific integration
Every configuration is reviewed against the actual robot, workpiece, fixtures, weld access and workshop conditions.
Engineering record
Expertise, with a named record.
BOCHU's intelligent robotics division issued this certificate of honor to Zhu Guoqing on 19 May 2026, recognizing his skill in intelligent machine operation.

Two ways to establish the workpiece.
The BOCHU documentation describes model-led welding and reverse modelling as different acquisition routes. TitanWeld keeps both inside one engineering review.
With a model: verify the handover
Start with a representative assembly, its model revision, weld requirements and fixture arrangement. Agree the Tekla export or equivalent model format with the receiving team.
Establish the physical part’s relationship to the digital reference, then review seam extraction, edited welds, robot posture and non-welding travel in simulation. The usable welding envelope depends on torch posture, placement and interference.
Without a model: inspect the reconstruction
Set exposure and the region of interest to include the workpiece while excluding the floor. Record the scan pose, acquire data through external-axis travel, then inspect the point cloud and reconstructed solid.
Check missing features, obstructed faces and excluded detail types before generating the welding route. A reconstructed solid and a supported weld are separate review results.
Set the scan region around the part
The original interface shows the region of interest enclosing the workpiece. Keep the floor outside that region and check exposure before recording the scan pose.

Compare point cloud and reconstructed solid
Inspect both representations, rotate the view and check incomplete or obscured features. Reconstruction supplies the geometry for planning; weld support is checked separately.

BOCHU technical illustrations
See the geometry behind the boundary.
Original figures from the supplied BOCHU manuals show where a feature fits the documented scope and where another engineering route is needed. Open each figure for its complete dimensions.
Crossing stiffeners: angle and extension
The included angle must exceed 30°, with an overlap extension of at least 40 mm. Both conditions apply at the crossing; the source diagram marks the required extension.

Inclined plates and recessed edges
This family requires plate dimensions > 100 × 100 mm, thickness < 15 mm, a plate-to-base angle of 60°–120° and a base intersection > 50 mm. For the illustrated recess, length > 20 mm and depth > 30 mm.

Curved webs and deformation
The curved-web example specifies curvature deviation < 30 mm. The general table lists web bending ≤ 30 mm and vertical-stiffener bending ≤ 20 mm. Confirm the applicable release at an exact boundary.

Side-attached plates: excluded from this route
The red outline identifies a side-attached plate. This feature is outside the cited reverse-modeling scope, even when adjacent stiffeners are visible from above.

Square or rectangular sealing flanges
The documented flat-flange scope requires thickness > 10 mm and length and width > 50 mm. If chamfered, radius must exceed 5 mm. Circular outer flanges and sloped flanges are excluded; the round opening shown is not the outer boundary.

Torch posture changes available space
The original dimensioned drawing compares 0°, 22°, 36° and 45° torch postures and extension lengths. Use the configured torch, robot and fixture in simulation to establish the actual accessible envelope.

Top-open assemblies: width and depth together
This model-based example uses a 36° torch and X = 573 mm. At 200 mm depth, the width-direction weld requires at least 150 mm length; length-direction welding also requires width ≥ 150 mm. These posture-specific values are separate from the reverse-modeling D/W rule.

These values describe the cited English edition. The Chinese V1.0.1 edition uses strict height endpoints and a depth-to-width ratio < 1.5. Review the installed version near a boundary. Reconstruction error describes the recovered geometry, not final weld accuracy.
Side-attached plates and stiffener-scallop reconstruction fall outside the cited specification (pp. 6, 10). Purlin support plates may be reconstructed as solids, but the supplied CypWeld manual excludes welding them through the point-cloud reconstruction route. Confirm the installed software release.
Check material and surface condition
Mirror-reflective workpieces are not supported by the cited model-based scope. Aluminium does not support arc tracking and may cause reflection issues. Stainless-steel applicability and weld quality remain untested in that document; assess the part and complete trial welding before production.

Does model-led welding remove project setup?
No. Fixtures, welding procedures, simulation and engineering verification still depend on the project.
When is reverse modelling useful?
It can help when the workpiece is visible, measurable and within the documented geometry and deformation boundaries. TitanWeld confirms that fit before planning production.
