A Guide to EN ISO 15614-7: Specification and Qualification of Welding Procedures

EN ISO 15614-7 is the European adoption of the international standard ISO 15614-7, which specifies requirements and procedures for qualification testing of welding procedures for metallic materials — specifically for fusion welding of aluminium and its alloys. The standard is part of the ISO 15614 series that covers procedure qualification for various welding processes. EN ISO 15614-7 is the international standard governing

• Manual metal arc welding (MMA)
• Gas-shielded metal arc welding (MIG/MAG)
• Flux-cored arc welding (FCAW)
• Tungsten inert gas welding (TIG)
• Plasma transferred arc (PTA) welding
• Submerged arc welding (SAW)

Hardness Testing:

Crucial for hardfacing to ensure the desired wear resistance is achieved. Manual metal arc welding (MMA) Gas-shielded metal arc
