## What is W/WO?

Background 
When welders or welding operators are used for pressure welding, welders must be qualified for the welding process. ASME Section IX Table QW-416 list essential variables for welder performance qualification using arc welding process. Welder performance qualification must address all applicable essential variables for qualification. 

Applicable Code / Edition & Standards
The ranges qualified are in accordance with ASME Section IX 2023 Edition.

Utility
For inspection companies it is required to verify, if performance variables are addressed correctly and ranges qualified are in accordance with ASME Section IX and construction Code.

It is hard to determine quickly performance ranges unless dive into Section IX or use knowledge and experience (or memorization although not recommended), if you are one having this issue, than we have solution for you through this app.

Scope
This app address welder performance qualification variables for arc welding processes (OFW, SMAW, FCAW, GMAW, GTAW, SAW, PAW & LBW). Each variable is addressed separately so that you can do a spot check on required variable quickly and efficiently.

Competitive Edge
This app is different than those available in the market in that, you don’t have to generate QW-484A form to determine welder performance qualification ranges instead directly check individual variable with qualified range. Hence productive and efficient. 

Target Audience
This app targets inspection agencies, pressure items manufacturing organizations, quality control personnel, welders, welding operators, students who are involved in welding trades and institutions who are doing performance qualification testing.
