Welding QAQC Services

Welding Quality Control

GQS can help you maintain the highest standards in manufacturing or repair, providing quality assurance in plant integrity, safety and compliance within specifications.

Welding QAQC consists of the observation techniques and activities used to fulfil quality requirements. This may include working through Inspection and Test Plans (ITPs) or checking that:

  • the welder is suitably qualified
  • the welding procedure and parameters are correct for the material being welded
  • the welding consumable has been prepared correctly, and a range of other checks that need to be carried out to ensure quality control in the process
  • material traceability and document control is achieved

GQS can perform fabrication and piping inspections in accordance with standards such as AS 4458, AS 4037, AS 1210, AS 3920.1, AS 4041, AS/NZS 1554.1, AS/NZS 3992, AS 2885.2, ASME B31.3, DNV-OS-F101.


Our Process

  • Checking personnel are qualified for tasks
  • Oversee welder/welding operator qualification tests.
  • Identify and control project materials and consumables
  • Ensure fabrication process is being conducted in accordance with project tolerances, specifications, and procedures
  • Work through project Inspection and Test Plans (ITPs)
  • Identifying, marking and recording of component/ weld joint for traceability
  • Checking and recording the welding procedure and parameters are correct for the material/ component under fabrication
  • Checking pre-heat and inter-pass temperatures are as per the welding procedure

The Welding Procedure Specification

GQS can ensure weld procedures are developed and qualified to meet the requirements of the applicable standards and client specifications prior to the commencement of production welding.

The Welding Procedure Specification (WPS) is the formal document describing the welding process and procedures. It is a guide to the welder that an accepted procedure can repeatably achieve quality welds.

Our Process

  • Determine and develop welding procedures
  • Ensuring relevant code compliance with regards to NDT, mechanical testing and procedure qualification documentation
  • Creating a practical written instruction for the welder/ welding operator
  • Controlling welding
  • Ensuring consistently sound welds are produced to give customers confidence for their welding project

Welding Supervision

GQS has the capability to manage welders and welding operator qualification tests to ensure that project personnel are able to perform within the parameters of the Welding Procedure Specification. This process sees the welder or welding operator perform under test conditions to weld an item using a specified welding position with specified welding consumables and materials, travel speed, amps and volts. The audit of the welder/ welding operator to pass the test may include visual, radiographic and/or mechanical testing and will prove the capability of the welder/ welding operator in the field in accordance with the required specifications.

These principles include:

  • Correct joint setup to drawing
  • Using the correct welding consumable
  • Use of preheat
  • Following the welding procedure in terms of amps, volts and travel speed
  • Inter-run cleaning and run sequence
  • Final visual inspection
  • Arrange for non-destructive testing and destructive testing
  • Qualify welders to required procedures
Pressure Equipment Inspection

GQS provides certified In-Service Inspectors to inspect pressure equipment, including boilers, pressure vessels, and pressure piping.

Workplace Regulations require that pressure equipment be regularly inspected and maintained in a safe operating condition.  It is the owner’s responsibility to ensure safe operation and maintenance of pressure equipment under the relevant countries’ jurisdiction standards. To ensure pressure equipment integrity, all pressure vessels and pressure-relieving devices shall be inspected at the intervals/frequencies per jurisdictional requirements. The appropriate inspection must provide the information necessary to determine that all the essential sections or components of the equipment are safe to operate until the next scheduled inspection. Regular inspections must be planned, implemented, evaluated, and comprehensively documented.


Additional to performing required inspections, GQS also guides clients to meet statutory compliance requirements with cost-effective systems. This information and guidance will satisfy the Occupational Health and Safety Authority and relevant Codes and Standards, as well as and more importantly, protecting the safety and health of persons in the workplace and public.

Our Process:

  • Assist with pressure equipment design review.
  • Perform pressure equipment construction inspections.
  • Ensure pressure equipment installation is as per applicable standards.
  • Perform commissioning inspections.
  • Ensure that pressure equipment has a documented commissioning procedure.
  • For pressure equipment operation, assist in establishing and implementing a suitable safety management system and procedures.
  • Assist in hazard identification, risk assessment, and risk control.
  • Ensure that suitable written procedures are prepared and implemented to manage changes and alterations to equipment, process technology, and operating condition.
  • Carry out external pressure equipment operational inspection and internal offline inspections.
  • Carry out inspections for remaining life determinations or purchase of an asset.
  • Determine the maximum allowable working pressure for re-rating purposes.
  • Perform decommissioning inspections.
