NDT services on Railway Components

Image
Non Destructive Testing (NDT) is required on most of metal components of Indian Railways during procurement of raw materials or on completion of machining and fabrication. NDT services  such as Ultrasonic testing (UT), Magnetic Particle Testing(MPT), Liquid Penetrant Testing(LPT), Radiography Testing (RT) &Visual Inspection Testing(VT). The Indian Railways require the manufactures to attain ISO 3834 Certification to become vendors for Indian Railways. Welded Components manufacturing,vendors can also upgrade to ISO 15085 certification to enter into Global and bigger market of welded railway components. In order to achieve ISO 3834  or ISO 15085 , we Advanced Quality centre assists you in right path by preparing you the welding procedure specification (wps) as per ISO 15614 and welder Qualification as per ISO 9606. We also consult & witness the mechanical testings of the welded Test specimens before approval of WPQR and WQR. What is Welder Qualification? Certifying we

Inspection of Automobile Components

Inspection of Automobile Components Automobile components manufacturing companies requires high quality standards and quality management   systems (QMS), to deliver high performance machines at low cost, they have to reduce cost of quality (COQ) by implementing various quality control tools such as Ishikawa, Six Sigma, %s and much more. How are NDT services used   in automobile components? In order to reduce the rejection of machined components due to raw material defects such as Shrinkage, blow holes, inclusions, cracks, etc., It is best to identify the defects at time of raw material purchase,   we offer our Non-destructive Testing   NDT services at supplier end or company storage yard, the various NDT method we offer are as follows ·          Ultrasonic Testing UT – for finding Internal defects ·          Magnetic Particle Testing MPT – for finding surface & near surface defects in Ferro magnetic material (the materials which has major content as Ferrou

Non Destructive Testing used to find defects in weld joints

How to find defects in Welded Joints and why Non Destructive Testing ? Welding is a process of joining two metals which are similar in metallurgical properties, welding utilizes heat to join metals, the heat can applied to the base metals by various processes , few of them are electric arc, friction , electric resistance & gas flame. The weld joints tend to have defects due to various reasons, few of them are as follows Welder skills,  Excess Current/   Low current, Moisture content in metal or filler wire Windy environment   Less inert gas flow Over speed or low speed welding   Excess heating or improper cooling rates and Much more….. There are various possible Weld defects, few are as follows                 Undercut, Under fill, Improper weld bead, Cracks, HAZ Cracks, Porosity, Cluster/Aligned Porosity,   Lack of Penetration, Lack of Fusion, Excess Penetration, Slag Inclusion. Craters, Crater Pipe, Star Cracks, Arc Strike, Spatters, Poor-Restart
