Welding is a modern manufacturing process that joins two or more materials. Just joining the two members is not enough to withstand the loads for longer duration. Hence it is essential to prove that a welding procedure meets the quality standards set forth and also to ensure the welder is capable of producing consistently good quality, defect free welds.

A welding procedure is a systematic method that is used to repeatedly produce sound quality weld joints. Various national and international fabrication codes, standards (e.g. ASME, AWS, BS EN ISO, API, DNV, AS or CSA) and client specifications are currently being followed to prepare Welding Procedure Specifications (WPS) to qualify the fabrications welding procedures. The Procedure Qualification Record (PQR) is a document that consists of record of test results on the welded coupon.

The field of non-destructive testing (NDT) comprises a vast array of analytical techniques that are applicable to a wide range of industries. These techniques can identify and assess defects and examine the properties of all kinds of materials and structures without causing any damage. As NDT in no way alters the part or structure under inspection, it is an extremely useful technique that can lead to cost and time savings when applied to product evaluations, asset management and fault identification and repair.

NDT methods such as ultrasonic inspection, magnetic particle inspection, liquid penetrant testing, radiographic testing, remote visual inspection and eddy current testing are now in standard use in civil, aeronautical and systems engineering. Advances in NDT enable the generation of 3D images of faults and have revolutionised many sectors.

Through our advanced NDT solutions, TIS can reassure its clients that their assets are in compliance with all applicable standards. The technical assurance delivered by TIS also minimises the level of risk to the assets in question as well as helping to maintain productivity.

Today, ISO 9001 certifications have become standard for company suppliers as verification of internationally standardized qualification. An ISO 9001 certification enables companies to market themselves as ISO 9001 certified to attract new clientele, and qualifies companies to partake in project bidding.

Furthermore, ASME certification is the clearest way to tell customers, supply chain, industry, and regulators that your company is committed to public safety and quality. ASME Conformity Assessment program is the leading, universally recognized, independent Quality Assurance (QA) program that certifies that manufacturing, power generation, stamped products and parts fulfill the requirements of relevant ASME codes and standards. It certifies that stamped items conform to ASME standards, including the ASME Boiler and Pressure Vessel Code (BPVC), the Bioprocessing Equipment (BPE) Standard, and/or Reinforced Thermoset Plastic Corrosion Resistant Equipment (RTP-1) Standard. The Mark gives confidence that relevant QA processes, products and parts are safe, high-quality, reliable and consistent. In many countries, ASME certification is a means of complying with regulations, while also promoting global commerce.

Also, If you are producing a steel or aluminum construction product which is being sold in the UK or the wider EAA, there is a legal requirement for you to CE Mark this product. A new EU standard EN 1090 for structural steel and aluminum is due to come into effect in July 2014. From this date, all components supplied into Europe will need to conform to this standard and be CE marked. There are four execution classes (EXC1 to EXC4), with the number rising as complexity and thus compliance strictness increases. For example, a handrail may be classified as EXC1 and a bridge EXC4. EXC2 is the most common specification.

We provide consultation for our clients with an all-inclusive manual complete with all the information and recommended procedures your company will need to follow for proper certification. Examples of standards TIS commonly help organizations get certified to:

  • ISO 9001 Quality Management System standard
  • ISO 14001 Environmental Management System standard
  • ISO 45001 Occupational Health & Safety Management System standard
  • ISO 3834
  • CE MARK EN 1090 EXC 1, 2, 3, 4
  • ASME U S R
  • API Q1 Q2 Quality Management System standard
  • API monograms

Companies want to know, before placing an order, that their chosen manufacturer has the necessary infrastructure, systems, processes and capabilities to fulfil it. They also need to ensure that local and international standards of quality and safety are consistently maintained across all of their international vendors, and throughout the manufacturing and delivery process.

From multi-national companies with complex international supply chains to smaller businesses facing increasing manufacturing costs, more companies are looking to lower-cost vendors in countries with less developed quality, sourcing, manufacturing and delivery processes. This requires companies to maintain consistent, acceptable standards while working with a range of vendors across a variety of territories.

We can help you gain a complete understanding of vendor capabilities through a systematic and independent vendor assessment. Our reliable, accredited auditors carry out internal audits, allowing companies and their vendors to meet quality standards without the cost of retaining an internal auditor on staff.

While the criteria are tailored to suit your needs, audits typically focus on a vendor’s systems, practices and capabilities. Audits may include pre-contract assessment and compliance testing to international standards, for example quality (ISO 9001), health and safety (ISO 45001), environmental management (ISO 14001) and laboratories (ISO 17025). We also provide guidance for corrective and preventative actions in light of an audit’s findings and followup assessments to confirm the effective implementation of those actions.

We can support your auditing and assessment needs anywhere in Vietnam. Our expert staff are located in major industrial centers, providing timely and cost-effective access to expertise, with the added value of in-depth local knowledge.

Our Total Quality Assurance auditors are qualified to evaluate companies to both local and internationally accepted standards. And to keep pace with current standards and legislation, we are dedicated to continued training, development and competency testing.

Technical auditing and assessment services help insulate your business from the risk associated with choosing suppliers. In addition our services can help reduce costs, improve quality, and promote continuous improvement.
