ISO 15609-6:2013

Overview

ISO 15609-6:2013 is an international standard developed by the International Organization for Standardization (ISO) that specifies requirements for preparing welding procedure specifications (WPS) for laser-arc hybrid welding of metallic materials. This document is a crucial part of the ISO 15609 series, focusing specifically on the unique considerations and variables involved in laser-arc hybrid welding processes. The standard outlines the information that must be documented to ensure the repeatability and quality of welded joints, supporting manufacturers in achieving robust and consistent welding results in industrial applications.

Key Topics

ISO 15609-6:2013 covers the following primary topics for laser-arc hybrid welding procedure specifications:

• Manufacturer and procedure identification: Proper documentation of the manufacturer, WPS, and references to welding procedure qualification records (WPQR).
• Parent materials: Identification of the materials involved, including specifications, product form (rolled, forged, cast), and material dimensions such as thickness and diameter range.
• Welding process: Detailed description of the laser-arc hybrid welding process, using correct ISO process designations.
• Joint design and preparation: Sketches and details regarding joint configuration, preparation methods like cleaning and degreasing, and joint protection if needed.
• Welding technique and fixtures: Information about techniques such as oscillation, fixture and tooling methods, and use of jigs or backing materials.
• Filler material: Specifications, dimensions, and any necessary treatment of wire or strip electrodes.
• Equipment details: Specifications for laser and arc welding equipment, beam delivery and focusing systems, and handling systems including seam tracking.
• Welding parameters: Laser and arc process parameters including power, pulse settings, welding speed, shielding gases, and geometric considerations.
• Thermal conditions: Requirements for preheating, interpass temperature, and post-weld heat treatment (PWHT).
• Post-weld operations: Mechanical and chemical treatments required between welding runs and after the weld is completed.

Applications

Laser-arc hybrid welding is used in industries demanding strong, high-quality welds on metallic materials, such as automotive manufacturing, shipbuilding, pipeline construction, and heavy equipment fabrication. ISO 15609-6:2013 helps manufacturers:

• Develop comprehensive welding procedure specifications for new production lines or specialized projects.
• Demonstrate compliance with international quality standards when qualifying and documenting welding processes.
• Enhance process consistency, efficiency, and safety by providing structured guidance for all critical welding variables.
• Facilitate communication and clear documentation among engineers, welders, production managers, and quality control staff.

By adhering to ISO 15609-6:2013, organizations can improve product reliability, reduce the risk of welding defects, and more easily adapt to changing material or process requirements for laser-arc hybrid welding.
