The WPQ record indicates the ability of the welder or welding operator to deposit sound weld metal. AL ASAS conducts destructive and non-destructive tests on a weld coupon provided by the welder to determine whether the welder is capable of producing a good weld quality using the welding processes, materials and prescribed procedures. Upon passing […]

Following a variety of international codes and standards, we perform welding procedure qualification tests on your welded samples to determine compatibility of welding consumables and base materials. We conduct our radiography and mechanical tests to comply with American Society of Mechanical Engineers (ASME), American Welding Society (AWS), American Petroleum Institute (API), and project specifications. Welding […]

AL-ASAS NDT Services is well versed in Welding Procedure Specification development. We develop the Welding Procedure Specifications to be used to get acceptable Welding Procedure Qualifications that will satisfy most international codes and standards.

Our Integrated Third Party Inspection team represents interest of client throughout the project and our service ensures right & cost effective solutions for the project requirements. We are providing the services by our experienced AWS/CSWIP /BGAS certified inspectors to carry out QA/QC inspection and Plant inspectors qualified with API 570/650 our scope below to our […]

Preheating involves rising the temperature of the parent material locally, on both sides of the joint to a value above ambient. The need for preheat is usually determined by the pertinent fabrication code and verified by the weld procedure qualification test. Preheat may be required as an aid to welding for one of the four […]

During the welding process, the two metal pieces being joined are subject to extreme temperatures and can cause the crystalline structure of the metal to pass through various metallurgical phases. As a result, hardening and embrittlement of the metal can occur to varying degrees (usually dependent on carbon content). Heat treatment is designed to reduce […]

A highly effective surface analysis technique, Liquid Penetrant Testing (LPT) is used by AL-ASAS Inspection to detect cracks and other surface breaking flaws. Special equipment is available for the testing of turbines, compressors, and pumps.

Magnetic Particle Inspection (MPI) is used to detect surface and subsurface cracks in ferroelectric materials such as iron, nickel, cobalt, and some of their alloys. MPI is also used on cut and beveled pipe ends before welding to make sure there are no parent material flaws. MPI is also used by AL-ASAS Inspection to detect […]

Visual Testing (VT) is the most common and usually first NDT examination step when the inspector using his eyes to detect any visible discontinuities and also to interpret visual data from other NDT processes. Inspections may require use of magnifying glasses, mirrors or Borescope for a closer look or viewing material in limited access locations. […]

Surface preparation For any given paint system, surface preparation is the single important factor which would determine its performance or the performance of any coating is directly dependent upon the correct and thorough preparation of the surface prior to coating. The most expensive and technologically advanced coating system will fail if the surface preparation is […]
