How it works
The technique is able to distinguish ok and nok welds based on individual customer’s criteria. The principle is in laser excitation of the weld surroundings and recording of the heating and cooling phase with infrared camera. The surrounding is not influenced by previous welding. In this area, even thermo-optical properties can be expected.
This prevents of uneven heating which can mask small differences between thermal behavior of ok and nok weld. Laser heating can be individually adopted for individual types of weld (materials, sheet dimensions, etc.) and thus meet demands on inspection from time and cost perspective.
Comparison with competitive methods
| Automated | Manual | ||||
| LabIR SpotWELD | Current IR NDT methods | Ultrasound automatic testing | Ultrasound manual testiní | Destructive testing | |
|---|---|---|---|---|---|
| Principle | Laser + uncooled thermographic camera | Laser + cooled thermographic camera | Robotic ultrasound probe | Manual ultrasound probe | Chisel test, cross section, tensile test |
| Nondestructive
Testing will not destroy the product or affect its properties in any way.
|
One product is destroyed and tested.
|

| Noncontact
The measuring system does not have to touch the sheet metal, which makes measuring faster.
|
|||||
| Unattended testing of all products
Fast automatic testing in the production line.
|
|||||
| Without consumables
No consumables (emulsions, water, membranes) etc. are required to perform the test.
|
The test requires, for example, emulsions or replacement of membranes.

| Access from only one side of the sheet metal
The measuring system is located on only one side of the weld.

| Not affected by the optical properties of the weld
The test can handle weld contamination and local emissivity changes.

Nondestructive
Noncontact
Unattended testing of all products
Without consumables
Access from only one side of the sheet metal
Not affected by the optical properties of the weld
Optical properties in the weld area are an obstacle and reason for measurement inaccuracies.
The most common methods uses a high-energy pulse and a cooled thermographic camera.
Nondestructive
Noncontact
Unattended testing of all products
Without consumables
Requires access to both sides of the sheet metal
Classical IRNDT methods for weld testing require access from both sides.
Optical properties of the weld prevents correct measurement
Optical properties of the weld are the reason of measurement errors.
