Optimising overlap (through-penetration) welding of copper and aluminium
Grade of Laser Welding Specialist (for automated applications only, not for manual laser welding)
Your design is fixed: it will be overlap welding on special materials – aluminium alloys and copper!
To implement this choice as effectively as possible, discover and learn good practice, from design through parameter setting to inspection.
The “Mastering Laser Welding” training course combined with this specialisation allows you to achieve the grade of Laser Welding Specialist.
Over 1.5 days
