What is the EN ISO 15614-11 Standard?

The EN ISO 15614-11 standard defines qualification tests for welding procedures for metallic materials using laser beam welding. Due to the high energy density and low heat input associated with laser welding, welding parameters require precise control.

The standard covers:

• Validation of the laser welding procedure (WPS)

• Material suitability and thickness ranges

• Laser power and focus control

• Evaluation of welding speed

• Use of shielding gas

• Non-destructive testing methods

• Mechanical tests and macro-examinations

How is the EN ISO 15614-11 Laser Welding Test Performed?

Laser welding testing is performed on test specimens that represent production conditions.

The process generally involves:

• Preparation of the laser welding procedure (WPS)

• Preparation of the test specimen

• Application of laser welding parameters (power, speed, focus)

• Visual testing (VT)

• Non-destructive testing (RT, UT, PT, or MT)

• Performance of mechanical tests (tensile, bend)

• Macro- and micro-section examinations

• Evaluation of results

• Creation of the WPQR (Welding Procedure Qualification Record)

Why is EN ISO 15614-11 Applied?

The EN ISO 15614-11 standard is implemented to ensure high precision and repeatability in laser welding operations.

Key reasons for its implementation include:

• Validation of laser welding procedures

• Control of heat input

• Reduction of welding deformation

• Standardization of production quality

• Minimization of defect rates

• Compliance with international requirements
