Details
The data contained in this Process Specification and Operator Qualification for Laser Hybrid Welding has been complied and reviewed by the C7D Laser Hybrid Welding Subcommittee of the American Welding Society, which includes representatives from manufacturers and users of laser beam welding and those involved in hybrid laser processes and equipment
Scope : 1.1 Scope. This specification covers processing and quality control requirements for Laser Hybrid Processing. Equipment includes any laser source (examples include, but are not exclusive to CO2, Nd: YAG, Diode, Ruby, Yb Fiber (Fibre), Yb Disk (Disc), Nd: Glass) in combination with an arc welding system (power supply, wire feeder, torch, etc.) as defined by AWS A3.0M/A3.0, Standard Welding Terms and Definitions Including Terms for Adhesive Bonding, Brazing, Soldering, Thermal Cutting, and Thermal Spraying. Specifically, this specification covers both (1) Laser Hybrid Arc Welding that uses both a laser to create a keyhole and GMAW (Gas Metal Arc Welding) to add filler material (resulting in a weld bead that is deeper compared to a traditional arc weld and wider than an autogenous laser weld) and (2) Laser Hot Wire Processing that uses a laser to create a conduction mode or keyhole mode molten puddle and an auxiliary power supply that adds heat to the filler wire that enters the puddle (resulting in a lower heat input weldment that could be used to weld joints or to add a hardfacing overlay). Tutorial information regarding techniques of welding or details of machine setup or operation of laser hybrid processing and laser hybrid processing systems is beyond the scope of this specification. For more information on this subject, refer to AWS C7.2. Recommended Practices for Laser Welding, Cutting, and Related Processes. 1.1.1 Materials. This specification covers all major engineering alloys including the following: (1) Ferrous Alloys (e.g., steels and stainless steels) (2) Non-Ferrous Alloys (e.g., Al alloys, Ni alloys, Ti alloys, Superalloys) (3) Heat-Resisting Alloys (e.g., Mo alloys, Ta alloys, W alloys) (4) Other Metals (e.g., Be and Cu alloys, precious metals) 1.2 Units of Measurement. This standard makes use of both U.S. Customary Units and the International System of Units (SI). The latter are shown within brackets [ ] or in appropriate columns in tables and figures. The measurements may not be exact equivalents, therefore, each system must be used independently. 1.3 Safety. Safety and health issues and concerns are beyond the scope of this standard, some safety and health information is provided, but such issues are not fully addressed herein. Safety and health information is available in the following sources: American Welding Society: (1) ANSI Z49.1, Safety in Welding, Cutting, and Allied Processes (2) AWS Safety and Health Fact Sheets (3) Other safety and health information on the AWS website Material or Equipment Manufacturers: (1) Safety Data Sheets supplied by materials manufacturers (2) Operating Manuals supplied by equipment manufacturers Applicable Regulatory Agencies Work performed in accordance with this standard may involve the use of materials that have been deemed hazardous, and may involve operations or equipment that may cause injury or death. This standard does not purport to address all safety and health risks that may be encountered. The user of this standard should establish an appropriate safety program to address such risks as well as to meet applicable regulatory requirements. ANSI Z49.1 should be considered when developing the safety program.
