Pakistan Welding Institute (PWI) was established in 1995 in Islamabad. Its basic goal was to achieve self-reliance in the design and fabrication of mechanical equipment for various industries, including oil refineries, fertilizer plants, and thermal power plants. With a 50,000 sq. ft. facility, PWI is a professional institution devoted to maintaining and promoting standards of excellence in Welding Technology.
PWI provides industry with technical support through advice & information, consultancy, Research & Development, and training & qualification. Its services & expertise cover all areas of welding & joining technology and materials engineering for metals and non-metals alike. It has gained membership from the International Institute of Welding (IIW) since 2000 and is working to acquire the status of Authorized National Body (ANB) and Authorized Training Body (ATB) from IIW.
Main Objectives:
- Implement qualification and certification programs for welding procedures and welders/operators.
- Produce skilled welders, inspectors, and supervisors to meet industrial demands.
- Develop standard procedures for the qualification and approval of welding equipment, materials, and workshops.
- Enhance the knowledge and skills of welding personnel through training courses, seminars, and workshops.
- Act as a consultant to address complex welding-related issues.
- Services Offered: PWI is dedicated to upholding and enhancing national standards of excellence in welding technology. It offers a variety of services to its clients in Welding and Joining technology, including:
- Training and Qualification: PWI provides short-term basic and advanced welding technology courses for welders, supervisors, inspectors, engineers, and managers. The institute offers technical support for the continuous improvement of welding education quality.
- Research & Development: PWI conducts industrial need-based applied R&D in the field of joining materials, aiming to increase productivity, enhance quality, and promote automation. Teams of specialists carry out R&D projects for the industry to improve efficiency, reliability, and profitability.
- Repair & Maintenance: PWI addresses industrial challenges such as cracks, wear, corrosion, and abrasion by providing repair and maintenance services for all types of equipment. Products of various sizes can be repaired at PWI and at the client’s site.
- Welding Equipment: PWI is equipped with both conventional and sophisticated equipment, capable of welding almost all commercially available engineering materials ranging in thickness from 0.3mm to 300mm.
Facilities offered
- The Material Testing Facilities: At PWI, they include comprehensive services such as chemical analysis, ferrite content measurement, mechanical testing, and welding equipment calibration. Chemical analysis uses the Spark Emission Technique to detect various elements in alloys, while ferrite content in stainless steel welds is measured using electromagnetic induction. Mechanical testing evaluates tensile, compressive, impact, weldability, fatigue, and bend properties using a 100-ton computer-controlled universal testing machine. Additionally, PWI creates NDE test samples with known flaws for training and qualification in accordance with ASME, API, and other standards. PWI also offers rigorous calibration and validation of welding equipment to ensure consistent weld quality.
- Cutting Facilities: PWI offers advanced cutting facilities, including Oxyfuel Gas Cutting with manual and semi-automatic portable machines for up to 300mm, Air Plasma Arc Cutting for stainless steel (50mm), carbon steel (300mm), and non-ferrous metals (50mm), and Mechanical Cutting (Band Saw) with a capacity of 520mm in height and 700mm in width.
- Heat Treatment Facilities: PWI has a fully automatic high-tech electrical resistant stress relieving and preheating heat treatment unit with 120kW power, six individual programmers, and a six-point chart temperature recorder for welded joints.
Pakistan welding society (PWS)
PWI established PWS to organize conferences, seminars, and meetings for the local industry. In addition, PWS provides various levels of membership with benefits such as access to resources, networking opportunities, and professional growth. Membership forms are available for individuals and corporate entities.
