  Application of flux cored arc welding (fcaw) without pre-heating for heavy structures in ship building fabrication & construction of heavy offshore structural steels

  By Jagan Rao K.S, Dr. Bh. Nagesh, I.N. Niranjan Kumar

  Abstract: In fusion welding processes, the reason often given to explain the need for preheating, controlling the inter pass temperature (in multi-pass welds), and post-weld heat treatment (PWHT) is to reduce the risk of residual stresses and it can be removed by heating weldment in the heat affected zone (HAZ). Cold cracking is a hydrogen embrittlement phenomenon, often referred to as hydrogen induced cracking or HAZ cracking. During the construction and …

  STUDY ON THE FAILURES OF WELD JOINTS OF ROOF HOOPS & BIAS MEMBERS IN THE PROJECT JEWEL ROOF CONSTRUCTION AND APPLICATION OF FLUX-CORED ARC WELDING TO AVOID FAILURES

  By Dr. Bh. Nagesh, Mr. Jagan Rao K.S, I.N. NiranjanKumar

  Abstract: During the construction of the roof structure of the commercial interconnection between the three airport terminals of the Changi Airport in Singapore, several failures have been noticed during the welding of roof hoops and bias members. In this context, experimental studies have been performed on transient heat transfer in welding distortion control by using flux-cored arc welding process (Self Shielded-SS) by using three(3)-dimensional welding in High Strength Low Alloy (HSLA) …
