1. Certifications & Training

A professional welder should hold recognized certifications (ISO, CE-related standards, or sector-specific welding certificates). These documents prove that the welder meets safety and quality requirements.

2. References & Previous Projects

Always ask for examples of past work. Photos, case studies, or client references from similar projects give you a clear idea of workmanship quality.

3. Experience with the Right Metal Type

Steel, stainless steel, aluminum, and cast iron all require different techniques. Make sure the welder has hands-on experience with the exact material your project needs.

4. Knowledge of Welding Processes

MIG, TIG, or electrode welding are not interchangeable. A professional welder should explain why a certain method is best for your project—not just apply a standard solution.

5. Quality Control Practices

Visual inspections, penetration tests, or non-destructive testing methods ensure weld strength and longevity. Quality control is not optional—it’s essential.

6. Clear Contract & Warranty

A proper agreement should define delivery time, tolerances, revision terms, and warranty coverage. This protects both sides and avoids misunderstandings.

7. Workshop & On-Site Capability

Some projects require workshop production, others on-site welding. A reliable partner should be flexible and well-equipped for both.
