Valve Investment Casting: Is The Process Economical?

1
How The Welding Repairing Is Done For Valve
Investment Castings In India?

• Welding is a process used by manufacturers of
  valve investment castings in India for repairing
  distinct range of casting components. It is done
  to surface casting defects using different
  welding material and procedures. Distinct types
  of welding are-
• Arc welding
• Carbon dioxide welding
• Plasma arc welding
• Submerged arc welding
• Metal arc welding

• To perform the welding process, manufacturers and
  repairing centers of valve castings require
  certain things, such as-
• Valve belonging to the pressure piping components
• Welding process
• Technical level of welders
• Equipments
• Specialized technology
• Materials
• Management
• The person performing welding should possess all
  basic skills and rules required for the process.
  When we actually required such person to perform
  welding? The need of welder arises where valve is
  extensively damaged. Welder is a person who
  repairs all such damages using welding technique.

Is The Process Economical?

• When you factor the time and repair costs to
  welding, you will determine that replacement of
  the part with the new one is more economical.
  This suits well in the case of internal parts,
  such as valve nozzle or disk, where machining is
  required once the welding process is done. The
  direct costing for welding and machining are
  rather insignificant as majority of people
  consider easy replacement methods over welding.
  Replacing equipment is a way easier and
  economical method unlike welding. You wont
  require skilled welder to repair the damage, but
  you will be needed professional assistance for
  replacement. Professional assistance is easily
  available however, reliable welders are hard to
  discover.

• Weld repairs are usually done when the valve
  investment casting body has a defect that needs
  to get fixed. Valve body is something which is
  not readily available in spare parts market. This
  is why sometimes people call the welders to fix
  the defect and make the equipment working like
  before. Though, there are manufacturers of valve
  investment castings in India who store some of
  the valve casting bodies to meet emergency
  requirements. You can get in touch with such
  manufacturers if you ever need valve castings for
  your application.
