Orbital Welding Solves Critical Metallurgical Problems in Furnace Shutdown
Very little clearance was available for the operation of the GTA welding machine.

Arc Machines' offers a free published article describing the use of orbital welding in a furnace shutdown project. The scope of the shutdown was to replace the furnace tubes in four VCM (vinyl chloride monomer) furnaces, which had previously been manually welded resulting in the welds having to be redone. AMI's orbital welding equipment was chosen for several reasons; one reason was to assure that the stringent quality control requirements of ANSI/ASME B31.3 code for severe cyclic chemical piping as well as ASME Section IX of the Boiler and Pressure Vessel Code would be met. Another critical consideration was the tight space restrictions for welding the upper convection coils.

Find out how a substantial increase in productivity was realized while quality requirements were met by Dow Chemical on this planned shutdown.
