Welding Services

Convoluted Technologies' qualified gas tungsten arc welding (GTAW or TIG) pressure welding staff and procedures are capable of servicing the industry with quality pressure pipe and tube welding work in accordance with relevant national and international codes and standards.

We have in house capabilities to layout jobs with Auto-Cad, to achieve exact specifications and minimize all re-work by pointing out problems before they arise in fabrication. Welder qualification by testing all welders on qualified procedures before proceeding to production welds. Welding procedures written in house and tested by NATA accredited laboratories, Inspection and Test Plans (ITP), Safe work method statements (SWMS) and Job safety analysis (JSA) written in house for specific projects as required.

We have our own in house hydrostatic and pneumatic test facilities, and dye penetrate testing. We are conveniently located near NATA accredited suppliers of mechanical testing to qualify new welding procedures and Non Destructive Testing (NDT) like radiography, ultrasonic, eddy current and magnetic particle to the relevant standards required for your job.

The relevant Australian standards are:
AS4041 is a pressure piping standard.
The welding procedures used for these codes are qualified in accordance with AS3992 Pressure equipment—Welding and brazing qualification
AS1796:2001 Certification of welders and welding supervisors. Is the qualification our welding personnel need to perform certified welding work.
AS 1554 Structural steel welding standard developed for statically loaded structural welds.

The relevant international ASME codes are:
ASME B31.3 is a piping code generally used for process piping (refinery piping and petrochemical piping etc).
ASME B31.1 is a piping code that is generally used for power piping (steam and condensate etc)
The welding procedures used for these codes are qualified in accordance with ASME IX Pressure Vessel Code.
The welders are qualified in accordance with ASME IX Pressure Vessel Code.
