About The Position

Sub Arc Welder – Long Seam or Girth Seam Night Shift (6 PM – 6 AM) Who We Are At North Shore Steel and our affiliated companies, we produce large-diameter pipe and structural products that require precision welding to meet demanding industry standards. Our girth seam welders play a critical role in final weld integrity, work that directly impacts quality, safety, and performance in the field. If you’re a Sub Arc welder who understands full-circumference welds, tie-ins, and maintaining consistency through rotation, this is where your skillset stands out. Position Summary As a Sub Arc Long Seam Welder, you will operate and manage Submerged Arc Welding (SAW) systems to produce high-quality long-seam welds on pipe and structural components. This role is focused on repeatable, high-quality production welding, requiring a strong understanding of machine setup, weld parameters, and quality standards. You will also support repair work when defects are identified, working closely with Quality and production teams. This is a night shift role (6 PM – 6 AM) and requires a welder who is dependable, detail-oriented, and able to maintain focus and consistency throughout the shift.

Proven experience operating Submerged Arc Welding (SAW) equipment
Strong understanding of weld parameters, heat input, and deposition control
Experience in pipe welding or large structural steel fabrication
Ability to read and interpret blueprints and welding schematics
Working knowledge of applicable standards (API, AWS, ASME)
Experience with multi-process welding environments (SAW, MIG, FCAW, SMAW)
Ability to identify weld defects and support repair processes
Strong attention to detail with a focus on consistency and quality
Reliable and able to maintain performance during 12-hour night shifts

Nice To Haves

Experience with long-seam pipe welding in a production environment
Familiarity with AWS and ASME standards for pipe manufacturing
Prior experience in high-volume, automated or semi-automated welding operations
Experience welding tandem electrodes
Experience with large-diameter pipe girth welding
Prior work in API-regulated environments
Experience working alongside NDE (X-ray/UT) quality processes
