Best-in-class for EH&S
The scope of the OHSAS18001 and ISO14001 certification covers all aspects of the company’s assembly, repair, stockholding and servicing activities.
ompressed air solutions and services provider, Sullair Australia, which has representation in New Zealand, recently achieved accreditation from Lloyd’s Register Quality Assurance (LRQA) Australia for its Safety Management and Environmental Management Systems. This accomplishment ensures that the company is operating to the world’s most stringent standards for Environment, Health and Safety (EH&S) management. The widespread benefits will be felt both internally by Sullair’s own workforce and externally by the company’s end users. The scope of the certification covers all aspects of the company’s assembly, repair, and stockholding activities, plus the servicing of packaged rotary screw and reciprocating compressor systems and associated compressed air equipment at end-users’ sites. The result will be enhanced standards
of product design and build, manufacturing, and after-market care, delivering extensive benefits throughout the company, and— more importantly—to the end user. OHSAS18001 and ISO14001 accreditation ensures that Sullair Australia’s compressed air solutions are designed with safety and environmental considerations as fundamental requirements. As a result, manufacturing and service facilities now set the standard for safety and environmental practices and performance within its industry sector. A key component of the accreditation is to certify that all safety and environmental standards are embedded into onsite servicing and repair operations at end user’s facilities. In practice, this means that when visiting a customer site, Sullair service technicians operate to best-in-class environmental and safety practices and procedures that meet—and often exceed—the end users’ own EH&S requirements.

Competent people important
hen the safety and reliability of a component or structure is dependant on the integrity of the welds holding it together, the accepted way of ensuring that this integrity is achieved is to weld to a recognised welding Standard. As a quality control tool, welding standards use a well-established methodology based on the following principles: • welding is carried out in accordance with a Welding Procedure Specification (WPS). • the welder undertaking the work is suitably qualified. • the welding is under the control of a welding supervisor. • inspection is carried out at appropriate stages to verify the weld’s quality. An example of fabrication where weld integrity is critical is the attachment of the towing eye to a heavy transport draw bar. This is a medium strength forging of high toughness with a chemistry that provides good weldability. To ensure its reliable service, it must be welded by a qualified welder strictly following a qualified WPS that involves preheating and a hydrogen controlled welding process. Qualifying the welding procedure involves the welding of a test piece which is then assessed by visual examination and a macro section. A macro section is a relatively simple method of verifying that the weld is of the specified size, has adequate fusion and penetration, and is free from unacceptable imperfections such as gas pores or slag inclusions. Achieving the quality of welding required for critical fabrication such tow eyes in an efficient and costeffective way requires competent personnel. The NZ Welding Centre

Macro-section of fillet weld used to qualify a welder for the tow eye weld
(a division of the Heavy Engineering Research Association - HERA) provides education and training for those who have responsibility for the supervision of welding, and the qualification of welding procedures and welders. Upcoming training events in March include a one-week course leading to qualification to Australian Standard AS 2214-2004: Certification of Welding Supervisors - Structural Steel Welding. This course has been successfully running for 3 years now and is available in Auckland and in Christchurch this year. In May, a one-day workshop on welding procedures to the widely-used AS/NZS 1554 welding standards will be available in a range of locations around the country. This is ideal training for designers, engineers, fabricators, welding supervisors, and inspectors who may need to develop, qualify or review the WPS.
