The welding process and electrodes must be suitable for all positions permitted by the WPS ASME Section IX QW-203.
Welding Procedure Specification WPS Design. Tujuan WPS Pada saat fabrikasi produk industri yang membutuhkan pekerjaan pengelasan seperti pembuatan ketel uap boiler bejana tekan pressure vessel struktur baja steel structure jembatan bridge pipa saluran pipelines dan lain-lain setidaknya ada 3 faktor yang harus diperhatikan yaitu keamanan safety ekonomi economy dan keterulangan repeatability. All Positions for Plate or Pipe. The Welding Procedure Specification WPS provides direction to the welder or welding operators for making sound and quality production welds as per the requirements of specified codes andor standards in case we are utilizing BS EN ISO Standards and AWS D11 code for the qualification of the WPS and WPQ.
