Failures & Repairs

Failures & Repairs

Rayner Engineering provides failure assessment, weld repair methodology development, weld engineering & WPS procedures, and repair design support for mining equipment, pressure equipment, industrial plant, and fatigue-critical components. With International Welding Engineer (IWE) support, we specialise in practical repair solutions for complex or critical welds where replacement may be expensive, slow, or unnecessary.

When a component fails, cracks, or receives a poor NDT result, replacement can often cost hundreds of thousands of dollars and cause major downtime. Rayner Engineering helps clients assess repair options, develop compliant weld repair methodologies, and extend component life where safe and practical.

Failure Assessment & Repair Engineering

  • Failure investigation and practical engineering assessment of cracked, damaged, or worn components

  • Review of NDT results, defect locations, crack indications, and repair feasibility

  • Weld repair methodology development for fatigue-critical components, pressure equipment, and industrial machinery

  • Repair design for mining equipment, civil equipment, structural components, weldments, and fabricated assemblies

  • Weld repair support for rockbreakers, crushers, vibrating screens, fixed plant, pressure vessels, and pressure piping

  • Repair-versus-replacement assessment to help clients reduce downtime and improve original return on investment

  • Engineering support for component life extension, maintainability, and safe return to service

Welding Standards, QA/QC & Inspection Support

  • Welding engineering support backed by knowledge of Australian and American welding standards

  • Repair methodology support for projects involving AS 1554, AS 1210, AS/NZS 3992, AS 4041, ASME B31 series, and ASME BPVC Section IX requirements

  • WPS and WPQR development for repair and fabrication projects

  • Weld supervision, weld inspection, and QA/QC documentation

  • NDT coordination, defect tracking, repair records, and inspection documentation

  • Inspection and Test Plans, repair reports, weld maps, and quality records for critical repair work

Rayner Engineering helps clients avoid unnecessary replacement costs by developing practical, engineered repair solutions for failed, cracked, or defective components. Our failure and repair services support safer decisions, reduced downtime, improved asset life, and better value from expensive industrial and mining equipment.
