Selecting a reliable welding company for installing and welding Industrial piping under pressure is a challenge many procurement specialists face. A poor choice of contractor can lead to delays, budget overruns, and quality issues. Based on my experience, here are the key steps and factors to help you make an informed decision.

Key Criteria for Selecting a Welding Company

1. Geographical Proximity
   Start by listing piping contractor companies located near your project site. This reduces logistical costs and simplifies coordination.
2. Financial Stability
   Check the company’s turnover. Financially stable companies are more likely to handle large or long-term projects effectively.
3. Team Size
   Investigate the number of employees. This reflects whether the company can meet your project deadlines.
4. Process Certifications
   Ensure the company holds relevant welding certifications (e.g., ISO, EN).
5. WPQR/WPS Library
   A well-maintained library of qualified WPQR/WPS (Welding Procedure Qualification Records/Welding Procedure Specifications) is a strong indicator of professionalism.
6. Technical Personnel
   A certified welding engineer (e.g., IWE/IWT) on staff significantly increases the likelihood of successful project execution.
7. Reference Projects
   Review the company’s past projects to evaluate their experience in similar work.

Additional Steps for Successful Selection

1. Evaluation of Equipment
   Assess the technology the company uses. Advanced methods, such as automated or TIG welding, improve precision and efficiency.
2. Quality Management Audit
   Confirm the company has a quality management system, like ISO 9001. Request examples of their procedures for inspecting welds (e.g., ultrasonic testing).
3. Logistics Analysis
   Ensure the company can quickly deliver equipment and staff to your site.
4. Risk and Safety Measures
   Verify compliance with occupational health and safety standards. Review their safety protocols on previous projects.
5. Warranty Discussion
   Inquire about warranties on completed work and ensure these are documented in the contract.
6. Reputation Check
   Look for reviews and ratings. If possible, contact past clients to learn about their experiences.
7. Trial Order
   Before committing to a major project, request a test job to assess the company’s quality and efficiency.
8. Insurance Coverage
   Confirm the company holds liability insurance to cover potential incidents.

Strategy for Company Selection

1. Initial Contact
   Send companies a project description and request pricing for welding, calculated by the length of welds (e.g., per inch). This helps compare pricing policies.
2. Price Filtering
   Analyse the pricing data and filter out offers outside your budget.
3. Blueprint Distribution
   Share detailed project drawings with shortlisted companies for precise cost and timeline estimates.
4. Meetings
   Arrange in-person or online meetings to discuss project specifics.
5. Quotation Collection
   Collect final quotes and compare proposals.

Final Steps

1. Site Visits
   Visit the company’s production facilities to evaluate their capabilities.
2. Contract Signing
   Once satisfied, proceed with contract negotiations and finalise the agreement.

Recommendations for Procurement Specialists

Procurement specialists should understand welding standards, materials, and technologies. If you lack expertise, involve a consultant to ensure proper planning and quality control.

Budget Estimation

Prepare a preliminary project estimate with the help of a specialist. This is essential for understanding the project scope and managing costs effectively.
