Great place to do Cswip 3.1.Recently i did my cswip 3.1 here .Whatever service you need regarding ndt and welding you can contact this institute. Their service was amazing. Cost wise also they are charging less than other institutes. Thanks especially to ganeshkumar sir for his kind and humble attitude.Practical sessions are more satisfying. Our instructor gopi sir and dhasarajan was an expert and was very clear in his method of teaching. All my questions were answered and the class interaction was very good. I would take another course with blastcorr
