  In ASME IX 2019 deleted supplementary essential variables “QW-405.2 welding positions” which given SMAW, FCAW, GMAW, PAW. See SUMMARY OF CHANGES in this code book. A qualification in any position qualifies the procedure for all positions Also see QW-203. A qualified in pipe also qualify for plate and vice versa. You may combine these WPSs in new procedure, also see QW-200.4

🧪 Hydrostatic Test Package Preparation Guide Inspection Point in ITP – QA/QC Controlled Document 🔧 General Requirements Hydrostatic testing is an essential inspection activity listed in the Inspection and Test Plan (ITP) . Before performing a hydrotest, the following conditions must be fulfilled : The hydrotest procedure has been approved by the client and/or consultant. All welding activities within the test boundary must be completed and inspected by all parties. Non-Destructive Testing (NDT) must be performed according to the project specification, with acceptable results . All relevant documentation must be collected for inclusion in the test package . 📦 11 Steps to Prepare a Hydrotest Package 1. Cover Page Include project name, client, contractor, system name, line class, and test type. A sample form can be customized to suit your project format. 2. Content Sheet Provides a summary index of documents included. Pre-fill standard informatio...

Following the topic, we would like to share you the quality document for small skid. Inspection check list Procedures and inspection should prepare and included in your hand, NDE procedure, NDE map, welding map and NDE plan also prepared. You should make a content of procedures for control, type of inspection report, below is sample list of procedure. Document control Too many drawings/ document per each skid, so it should carefully update with latest revision, Line list should be updated and control the piping spool number, all spools to be identified in the test package later. Shop drawing, document submission to be documented revision number, date of submission, date of return, and approval code, etc.   Inspection report To control and monitor all inspection reports, the assigned coding number should generate before starting issue.   Welding summary For structural steel For piping   Material receiving inspection MRIR for piping, bolting, gasket, fitting MRIR for consum...

  (IWE 1.08-1 - Figure 29: Welding voltage and welding current for different shielding gases) Above photo is an example to determine welding parameter with variant shielding gas. Example 1: 145A, 22V, 100% CO2 Example 2: 190A, 24V, 100% CO2 Example 1: 250A, 28V, 100% CO2 You are so referred to other shielding gas and variant welding parameter in IWE handbook -Module 1.08-1:2018 edition.
