Dear Mr Saini,  major difference between weld with buttering and weld overlay are given below: 1. weld over lay       a. weld over lay have two types, one is hardface over lay another one is corosion resistance over lay      b. when we required harder surface with higher hardness than base materail - hardface over lay is being used     c. when we required corrosion resistant surface in order avoid correcion- corrosion resistance over lay being used  2. weld with butter      a. During dissimilar welding applaiction, buttering being used      b, when joining carbon steel to stainless steel, the carbon steel side buttering can be done before joining to SS materail      c. purpose of buttering to avoid the dilution effect & lossing of alloying  elements from weld metal  you can refer AWS welding hand book for your further refernce.         Regards, Sankaran.S...

Hi elavarasan, Can you elaborate whether you have to machine 14mm plate to 8 mm for welding, or you have to make 8mm plate instead of 14mm.  Select the weld plate thickness based on your casting weld depth . Incase your casting weld depth requirement is more than 2 inch better you can for 40mm plate so that you can weld as much as the depth as standard requirement, make sure you have to get approval incase you are doing major weld on the part based on customer requirement.

Yes this would make  cost of welding quite high. As you know these piping are exposed for extremely harsh service environments, proven welding consumables are required to meet the design and construction and service requirements. Typical offshore pipeline design specifications such as DNV-OS-F-101 indicates one "type" of welding consumable for single sides welding of clad pipes.   I would think there are  some alternatives practiced in the industry,  in ...
