1. The user is solely responsible for certifying WPS & PQR. A professional welding engineer should design [considering the applicable Code and Standards] by selecting the essential welding parameters such as plate beveling, wire and flux specifications, amperes and voltage, welding speed, etc.

2. Rental Facility for Tank Welding Practice

Our company does not provide training; Girth Welders must be operated by an experienced submerged arc welding operator with an updated ticket. A rental facility is available to become familiar with our equipment and obtain the samples to qualify for the Welding Procedure Specifications (WPS), Procedure Qualifications Records (PQR), and Welder Qualification Test (WQT).

• The user should provide a steel-base plate with beveling, wire and flux.
• Minimum rental of five business days in an eight-hour shift. Includes: Two AGW-1-C and one SAW Welding Tractor.
• Maximum two operators at a time and one supervisor.
• Booking: Two to four weeks in advance.
• The user is required to provide a certificate of liability insurance.
