31 maj 2023 · Learn the steps to prepare a WPS document according to ASME Section IX code. Find out the essential, nonessential and supplementary variables for different welding processes and how to qualify them with test coupons.
19 mar 2024 · A welding WPS document, also called a welding procedure specification, describes the welding process, materials, and procedures for producing a weld that meets specified requirements. Welders use WPSs to produce welds consistently and repeatably, ensuring they meet the required quality standards.
WPS Qualified Range (ASME IX Guideline): Qualified Positions (Groove, Fillet): All Positions for Plate or Pipe. Unless specifically required otherwise by the welding variables (QW-250), a qualification in any position qualifies the procedure for all positions.
The WPS includes information on the type of welding process, such as Shielded Metal Arc Welding (SMAW), Gas Tungsten Arc Welding (GTAW), Gas Metal Arc Welding (GMAW), or Flux-Cored Arc Welding (FCAW), and the specific parameters that must be followed for each process.
A Welding Procedure Specification (WPS) is a formal document describing welding procedures. It is an internal document used by welding companies to instruct welders (or welding operators) on how to achieve quality production welds that meet all relevant code requirements.
18 gru 2020 · A welding procedure specification (WPS) is a guide for the welder or its user written in a recommended format by ASME or user-defined to ensure a sound weld deposit. Welding procedure specification (WPS) generally has a range given for welding parameters (current, voltage, heat input, gas flow rate & welding speed) to accommodate easiness for ...
