PROCESSES WE CERTIFY:
Shielded Metal Arc Welding (SMAW)
With this particular type of welding, the welder follows a manual process of stick welding. The stick uses an electric current to form an electric arc between the stick and the metals to be joined. This type is often used in the construction of steel structures and in industrial fabrication to weld iron and steel.
Gas Metal Arc Welding (GMAW/MIG)
This style of welding is also referred to as Metal Inert Gas (MIG). It uses a shielding gas along the wire electrode, which heats up the two metals to be joined. This method requires a constant voltage and direct-current power source, and is the most common industrial welding process. It has four primary methods of metal transfer: globular, short-circuiting, spray and pulsed-spray.
Flux Cored Arc Welding (FCAW)
This was developed as an alternative to shield welding. The semi-automatic arc weld is often used in construction projects, thanks to its high welding speed and portability.
Gas Tungsten Arc Gas Welding (GTAW/TIG)
Welding together thick sections of stainless steel or non-ferrous metals is the most common use for this method. It is also an arc-welding process that uses a tungsten electrode to produce the weld. This process is much more time consuming than the other three and much more complex, too.

OUR WELDER QUALIFICATION & WPS SERVICES:
Welding Procedure Specification (WPS) Development: The service includes the development of detailed welding procedure specifications based on the requirements of the specific code or standard. This involves determining the appropriate welding process, filler materials, preheat and interpass temperature requirements, welding parameters, and post-weld heat treatment procedures.
Procedure Qualification Record (PQR) Development: PQR development involves conducting welding tests and generating records that demonstrate the procedure's ability to produce sound and reliable welds. This process includes performing weld testing, such as bend tests, tensile tests, impact tests, and macro/micro examinations, to ensure compliance with the relevant code requirements.
Welder Qualification: Services related to welder qualification ensure that the personnel performing the welding procedures are qualified and certified according to the applicable code. This involves conducting tests to assess the welder's skill and proficiency, including visual inspections, destructive testing, and sometimes non-destructive testing methods.
Welding Procedure Review: As part of the service, welding procedures developed by clients or third parties are reviewed and assessed for compliance with the relevant codes and standards. This helps identify any discrepancies or areas for improvement to ensure the procedures meet the necessary requirements.
Code Compliance Consulting: Professionals experienced in AWS D1.1, D1.2, D1.3, D1.4, D1.5, and ASME codes can provide consulting services to ensure compliance with the specific code requirements. They offer guidance and support in interpreting the codes, resolving code-related issues, and implementing the appropriate welding procedures to meet the standards.
Welding Consultation and Support: Clients can benefit from expert consultation and support services, where experienced professionals provide guidance and solutions for specific welding challenges. This includes advising on code interpretation, suggesting alternative welding techniques, assisting in resolving welding-related issues, and providing technical support throughout the project lifecycle.
These services play a vital role in ensuring that welding procedures and qualifications are in line with the specified codes and standards, promoting safe and reliable welding practices in various industries and applications.
What is a WPS?
A Welding Procedure Specification (WPS) is a document that outlines the necessary steps and parameters to be followed in order to carry out a specific welding process. It provides a standardized set of instructions to ensure that the welding operation is performed consistently and meets the required quality and safety standards.
A typical WPS includes information such as the welding process to be used (e.g., TIG, MIG, SMAW), the type of welding material, the welding position, the welding parameters (e.g., current, voltage, travel speed), pre-weld and post-weld treatments, and any special instructions or precautions. The WPS is developed based on the specific welding code or standard applicable to the project or industry.
WPSs are essential in maintaining quality control and ensuring the repeatability and reliability of welds. They are typically developed and qualified through a series of tests and inspections to ensure that the welding procedure will result in welds that meet the required criteria for strength, integrity, and performance.
What is a WPQR?
A welder performance qualification (WPQR) is a document that shows that a particular individual is qualified to weld in accordance with a specific variables in accordance with the code in question.
This is accomplished by individuals successfully passing a weld test usually in accordance with or following the parameters of a qualified or prequalified welding.
If the welder has satisfactorily completed the procedure test then he is automatically approved but each additional welder must be approved by completing an approval test to an appropriate standard such as AWS, ASME, Mil-spec, AISC & LA City.

- Complete a weld test as stated above. The test should simulate production conditions and the welding position should be the position that the production welds are to be made in or one more severe.
- Test the completed weld in accordance with the relevant standard to ensure that the weld is clean and fully fused.
- Once the test is completed the necessary certification documentation will be generated by the WCIS personnel.
- Note that any changes that require a new welding procedure (WPS) may also apply to the welders approval, refer to the referencing code/ standard for precise details
