Which welding variables are documented in a WPS?

Which welding variables are documented in a WPS?

• A. Base metal, filler, position, current range, gas, and other approved variables.
• B. Base metal, filler, position, current range, gas, etc.
• C. Filler metal grade and supplier contact information.
• D. Testing methods and pass/fail criteria.

Answer: (A)

A Welding Procedure Specification lists the variables that must be controlled to ensure a consistent and quality weld. The best option includes base metal, filler, welding position, current range, shielding gas, and any other approved variables. These are the core factors that the welding procedure must specify so the welder knows exactly what materials and conditions to use and what parameter ranges are acceptable. The other choices miss or misplace elements: filler metal grade and supplier contact are procurement details, not WPS variables; testing methods and pass/fail criteria belong to qualification or acceptance documentation; and using vague terms like “etc.” leaves out important specified variables needed for repeatability.
