01ON-BOARD CAMERAS
Capture
Cameras built into the welding helmet film the weld zone and the working environment. The welder keeps their booth, torch and equipment: nothing changes in the gesture itself.
Travel speed18cm/min
Arc height4.2mm
Torch angle81°
Steadiness82%
MIXED REALITY · REAL-TIME AI ANALYSIS
For training centres, apprenticeship schools and industrial workshops
The gesture, finally measured
WELD-MENTOR analyses the welder's gesture in real time and shows the correction in their field of view.
Travel speed, arc height, torch angle, steadiness: instructors measure instead of estimating. Apprentices correct during the weld, not after.
THE PROBLEM
A trade that resists measurement
Training a welder is expensive: assessment stays subjective and every failed bead consumes material and time.
Assessment stays subjective
Gesture quality is judged by eye. The diagnosis depends on the instructor, varies from one centre to the next, and leaves no usable record.
Every failed bead costs
Filler metal, shielding gas, energy, machine time: learning by repetition carries a direct material cost.
The instructor is a bottleneck
One instructor cannot watch eight welding booths at once. Attention gets divided, progress slows down.
The industry is short of qualified welders
Recruitment needs in the metal industry remain higher than the flow of trained, qualified professionals.
OUR APPROACH
Capture, analyse, correct
Capture the real gesture, analyse it in real time, then show the correction in the welder's field of view.
02COMPUTER VISION
Analyse
Computer-vision algorithms extract the key parameters of the bead being laid and detect deviations from the expected gesture.
03REAL-TIME FEEDBACK
Correct
Feedback is immediate, displayed in the field of view, then consolidated for the instructor: per-apprentice history, session comparison, progress areas.
WHAT THE AI OBSERVES
The measured parameters
Travel speed
How fast the torch moves along the joint.
Arc height
Distance between the torch tip and the weld pool.
Torch angle
Torch inclination relative to the workpiece.
Gesture steadiness
Movement stability over time.
Weld pool stability
Detection of variations and instabilities.
Bead regularity
Consistency of width and height.
Spatter
Material projected outside the bead.
Restart quality
Soundness of the junction between two passes.
TECHNICAL SCOPE
Processes and compatibility
Priority processes
TIG (141), MMA (111).
Welder's equipment
Power source, torch and helmet kept, no forced replacement.
Mixed-reality hardware
Architecture designed to stay independent from any single headset manufacturer.
THE PRODUCTS
One technology, three uses
For the apprentice. Guided exercises, immediate visual feedback during the weld, progress measured session after session. Mistakes get corrected as they happen, not at the debrief.
- Guided exercises per process
- Visual feedback during the weld
- Progress history per session
- Comparison of completed welds
For the instructor. Real-time view of every booth, per-apprentice history, session comparison, results export. Attention goes where it matters most.
- Real-time view of every booth
- Per-apprentice history
- Session comparison
- Results export
For the welder on the job. Preparation checks, gesture monitoring in production conditions, support for operation traceability.

WHO IS BUILDING WELD-MENTOR
Built by a welder
WELD-MENTOR was not born in a design office. Dylan Alexandre runs ARC FRANCE, an industrial welding company, recipient of the 2018 French Senate Medal — French Republic, and represented France on the WorldSkills France national team. The parameters the solution measures are the ones a welder actually watches.
- TIG · stick electrode
- Radiographic inspection · WPS compliance
- Buried networks · gas pressure-reduction stations
THE COMPANY
ARC FRANCE
ARC FRANCE is an industrial welding company based in Villenave-d'Ornon, Nouvelle-Aquitaine, France. It works on fluid transport and distribution networks, in pipework, in environments where compliance is not negotiable. WELD-MENTOR is built on that day-to-day practice.
Processes mastered
TIG, MIG/MAG and MMA — rutile, basic, cellulosic — across standard industrial pipework diameters.
Inspection standards
Work subject to radiographic and ultrasonic inspection and WPS compliance.
Critical environments
Buried networks, gas pressure-reduction stations, district heating networks.
Site work
WHY IT MATTERS
Our commitment
Less material consumed to learn
Part of repetitive practice can be done without consuming filler metal or shielding gas. What is saved on material is reinvested in useful practice time.
A skill that can be passed on and proven
A measured gesture can be documented, compared and transmitted. That is what is missing today to speed up the training of a new generation of welders.

BEFORE WE TALK
Frequently asked questions
Does existing welding equipment need to be replaced?
No. The welder keeps their power source, their torch and their consumables. WELD-MENTOR is added to the protective equipment, it does not replace it.
Which processes are targeted?
TIG and manual metal arc as a priority. The exact scope is being consolidated with partner training centres.
Does the device get in the way of the welder's gesture?
The ergonomics and the weight of the helmet are design constraints addressed as a priority. It is a validation criterion for each phase, not a secondary point.
How is learner data processed?
Gesture data is processed for a teaching purpose, following a principle of minimisation. The scope of access, the retention period and the ways to exercise your rights are detailed in the privacy policy.
Does the employer have access to individual results?
The scope of access is being defined with specialised data protection counsel. No employer access is open by default.
When will the solution be available?
WELD-MENTOR is in development. The first demonstrations are open to a limited number of training centres and manufacturers.
Can we take part in a pilot experiment?
Yes. Interested organisations can get in touch through the contact form.
