The DNA of Structural Integrity
A crane, a lifting beam, or a structural frame is only as strong as its weakest weld. Poor weld penetration, slag inclusion, or incorrect pre-heating can compromise high-tensile steel, turning a heavy lift into a catastrophic risk.
Cranes Australia provides specialized weld inspection and engineering services. We don't just find cracks; our chartered engineers review your Welding Procedure Specifications (WPS), qualify your welders, and oversee critical structural repairs. Using advanced NDT, we ensure every millimeter of weldment meets the exacting requirements of Australian Standards.
Welding Standards

Welding Capabilities
Comprehensive quality assurance for structural fabrication and repair.
Weld Procedure Review
Engineering review and approval of Welding Procedure Specifications (WPS).
Quality Inspection
Visual and NDT inspection of structural welds against relevant AS/NZS standards.
Weld Mapping
Detailed traceability mapping of every weld, welder, and NDT result on a project.
Defect Investigation
Forensic metallurgical analysis to determine the root cause of weld failures.
Crack Detection
Surface and subsurface flaw detection using MPI, DPI, and Ultrasonic methods.
Repair Verification
Supervision and NDT of gouge-out and re-welding processes for structural repairs.
Why It Matters
The dangers of unregulated welding.
Hydrogen Cracking
Welding high-strength steel without correct pre-heat procedures leads to delayed hydrogen cracking, failing days after the weld is completed.
Subsurface Defects
A weld can look perfect on the surface but hide dangerous lack-of-fusion or porosity inside, severely reducing its load capacity.
Voided Warranty
Performing unauthorized or uncertified welding on a crane boom immediately voids the manufacturer's warranty and legal liability.
Our Process
Procedure Approval
Our engineers review and approve the WPS and PQR before any welding commences.
Visual Inspection
A certified welding inspector monitors fit-up, root passes, and final weld profiles.
Non-Destructive Testing
Volumetric (UT) and surface (MPI) testing is performed to ensure the weld is internally sound.
Compliance Sign-off
A comprehensive weld quality report is issued, verifying compliance with AS1554.
