  A Review on Shielded Metal ARC Welding

  By M. Prasanth Kumar, J. Kalpana Devi, Deepa Kodali

  Abstract: Shielded metal arc welding (SMAW) is the world's most popular welding process. In this process consumable electrode is used for generating arc. The electrode is coated with a shielding flux. The flux melts with the electrode metallic core, forming gas and slag, shielding the arc and the weld pool. The flux cleans the metal surface and protects the molten metal from oxidation and stabilizes the arc. The molten electrode metal …

  Micro Crack Formation in High Frequency-Electric Resistance Welding

  By Raghu Shant, Gokul Thummuluru, Anil Mahajan, Rajesh K. Goyal, T. S. Kathayat

  Abstract: The present paper discusses about the formation of micro cracks in base metal adjacent to the weld area during High Frequency-Electric Resistance Welding (HF-ERW) of 10'' outside diameter pipe. The micro crack formation has been analyzed with respect to chemical composition, microstructure, inclusion level, welding parameters and angle of weld flow lines.
