ABOUT US

Led by Adam, a highly experienced certified welder with decades of industry expertise. We don't just weld parts together - we develop practical solutions that work. Quality, safety and expertise on every project.

  • Structural Steel Welding

    Primary structural welding for commercial construction projects. We provide certified welding for building frames, supports and structural installations.

  • Container Fabrication

    Custom container modifications and conversions into garages, workshops, storage solutions and unique building structures. Full structural customization available.

Trusted by Leading Construction & Engineering Companies

Adam and the team at Onsite Welding regularly work alongside major contractors, construction companies, container specialists and government organisations across Canterbury.


Much of this work comes through reputation and referrals — companies know when specialist welding is required, they need someone experienced who can deliver quality work on-site.
