Member Welding- Concical Head

Member-to-conical head welding at Xuzhou Shengjian uses full-penetration butt welds with 100% visual and 10% ultrasonic inspection. WPS qualified to ISO 15614, welders certified to ISO 9606-1, and post-weld dimensional checks on every member. Rigorous quality assurance at one of the most critical steps in space frame manufacturing.

Technical Advantages

The member welding process for conical head connections at Xuzhou Shengjian joins the circular hollow section tube member to its conical end connector using a full-penetration circumferential weld — creating a permanent, high-strength connection that transfers both axial and shear forces reliably across the joint. Key features: • Full-penetration butt weld between CHS member and conical head • Weld inspection: 100% visual and 10% ultrasonic testing as standard • Welding procedure specifications (WPS) qualified to ISO 15614 • Welders certified to ISO 9606-1 — qualified for CHS-to-cone joints • Weld root and cap geometry controlled to minimize stress concentration • Post-weld dimensional check ensures overall member length tolerance This process is one of the most critical quality steps in welded space frame manufacturing. Xuzhou Shengjian's dedicated welding quality team performs in-process and final inspection on every member.
