WELDING

Welding Services by Al Jassar Engineering

At Al Jassar Engineering, we deliver world-class welding services, setting the benchmark for precision and reliability in industrial applications. Our expertise spans industries like oil and gas, petrochemical, construction, and manufacturing, providing welds for pipelines, pressure vessels, steel structures, and heavy machinery. With cutting-edge technology and a commitment to excellence, we ensure every weld withstands the toughest conditions, safeguarding your project’s success.

Our Expertise in Standard Welding

Our services adhere to the highest standards, ensuring flawless joints for critical applications. We specialize in:

• Pipelines: Welding for oil, gas, and water transport systems.
• Pressure Vessels: Ensuring leak-proof joints for petrochemical plants.
• Steel Structures: Joining components for construction frameworks.
• Heavy Machinery: Welding parts for manufacturing equipment.
• Tanks: Storage tank welds

We employ a wide range of standard welding techniques, including SMAW (Shielded Metal Arc Welding), GTAW (Gas Tungsten Arc Welding, also known as TIG), GMAW (Gas Metal Arc Welding, also known as MIG), FCAW (Flux-Cored Arc Welding), and SAW (Submerged Arc Weld). These methods ensure compliance with international standards like ASME IX, AWS D1.1, API 1104, and EN 287, guaranteeing welds that are strong, durable, and safe for industrial demands.

Heat Treatment for Weld Integrity

A key part of these services  includes specialized heat treatment to enhance weld quality. We apply post-weld heat treatment (PWHT) to relieve stresses, improve toughness, and prevent cracking in welded joints. Our process adheres to standards like ASME Section VIII, AWS D10.10, and ISO 17663 for heat treatment quality. Using advanced tools such as induction heating machines, ceramic pad heaters, and thermocouples, we precisely control temperature and cooling rates. This meticulous approach ensures welds achieve optimal mechanical properties, making them suitable for high-pressure and high-temperature environments.

Qualified Welders and Strict Procedures

What sets us apart is our team of qualified welders and workforce, certified to international standards like ASME IX and EN 287. We follow strict welding procedures, including Welding Procedure Specifications (WPS) and Procedure Qualification Records (PQR), ensuring consistency and compliance. Our Quality Management System (QMS) procedures, aligned with ISO 9001:2015, govern every step, from material preparation to final inspection. We conduct internal testing, such as visual inspections and dye penetrant tests, followed by external third-party testing, including radiographic and ultrasonic examinations, to verify weld integrity. This dual-layer testing ensures unparalleled quality.

Comprehensive Documentation for Transparency

Our commitment to excellence extends to complete documentation for every project. We provide detailed records, covering material certificates, welder qualifications, WPS/PQR, heat treatment reports, and test results. Each phase includes defined checkpoints to monitor progress and ensure compliance with standards like API 1104 and AWS D1.1. For example, we document non-destructive testing (NDT) results and third-party inspection reports, offering full traceability. This thorough documentation underscores our dedication to transparency, giving clients confidence in the reliability of our welds.
