Welding Quality Management System (WQMS)

About this Standard

Large fabricators address control of welding operations in their ISO9000 Quality Management. As for smaller companies, they may not have a Quality Management System (QMS) at all or their QMS might not be detailed enough to show how welding operations are managed. Such companies are usually required to have a Welding Quality Management System (WQMS) as it details how welding is managed in the factory. Specific information such as the size of the company, the materials that are usually welded, the industry sector, and the product range help determine the level of complexity involved in the WQMS. For a small company with a highly limited product range, complying with ISO 3438 is enough. Yet, some companies might need to maintain additional focus on control of welding operations and hence need to have a WQMS incorporated into their ISO9000 Quality Management.

Before Getting a Certification You Might Need:

Welder Qualification

A crucial step in implementing a WQMS is determining the skill of the welder/s working in the factory. This requires performing a Welder Qualification Test (WQT). Here the welder is asked to weld a test coupon according to the WPS. Then, the test coupon is delivered to authorities for the Radiography test and other mechanical tests. By receiving a satisfactory test report, the welder is officially recognised as a certified welder and may be employed. IntegPro can help your welders improve their skills and pass the WQT in quite a short time.

Welding Supervision

Having a skilful welder next to you helps you a great deal. Even if you do not need ISO 3834, you always want to ensure that the service you deliver will satisfy the customers. That’s why having a welding supervisor in your team is somewhat necessary. With the excellent welding supervision that IntegPro provides, you can rest assured that welding will be done with the best quality and precision.

Welding Inspection

Welding inspection involves several quality control checks carried out by welding inspectors to ensure the welded joints have the required level of quality and meet the standards. Typically, a good weld has a smooth and uniform appearance without any signs of penetration. If you intend to obtain the ISO 3834, you should first perform a welding inspection to make sure that your welding quality is in line with ISO 3834. To do so, you can reach out to our experts at IntegPro, and they will conduct a thorough welding inspection and let you know how well welding is performed in your company.

Welding Quality Management System

ISO 3834,

Simply put, ISO 3834 is the international standard for welding metallic materials. Obtaining the ISO 3834 has five phases which are System examination, questionnaire, self-audit, implementation and confirmation, and finally, validity. In the system examination phase, the company’s welding quality management system is examined and evaluated to see which areas require improvement. Then, the welding personnel must fill out a detailed questionnaire on their skills and capabilities as well as the facilities they have access to in the factory. Next, you should conduct a self-audit against the ISO 3834 checklist. After that, the assessment team will decide if the changes you’ve made in the system is in accordance with customers’ expectation. If things go well, you will obtain the ISO 3834, which will remain valid for five years. The process may sound a bit scary, but we’ve got your back. Our experts will guide you through all the stages and provide support throughout the whole process.

AS/NZS 1554, AS/NZS 3992

These are two well-known welding standards that are of great value to factories based in Australia and New Zealand. The primary objective of AS/NZS 1554 standard is to set welding rules for welding steel structures. AS/NZS 3992, on the other hand, is concerned with welding and brazing qualification in boilers and pressure vessels. Having these standards leaves no room for any argument against welding quality in your factory in Australia and New Zealand. Our seasoned experts can provide you with insightful tips on how to obtain these standards and enhance your service quality.


These are three common structural welding codes that set requirements for various welding-reladed issues such as testing, inspection, design specifications, approved materials, etc. These welding codes, in other words, define requirements for the most common welding processes. Each code shows what type of welding is carried out in a factory, what materials are used, and so forth. To help your factory stand out from the crowd, it should have a welding code in the first place. Reach out to IntegPro experts and seek their advice. They will certainly help you decide which welding code you need and help you get it in no time.

Welding Procedure Qualification Report (WPQR)

The Welding Procedure Qualification Report (WPQR) starts with writing a Welding Procedure Speciation (WPS). An experienced person writes the WPS and tests it to make sure that it has the required mechanical property. In doing so, every welding variable, such as preheat temperature, material strength, and material thickness and ductility, should be recorded and detailed in the report. The WPQR provides information regarding what happened during welding and what results were obtained.
