In a cement kiln of dia 4.75 mtr and 75 mtr long. the kiln is supported at three Tyre . one of the Tyre ( middle Tyre ) has developed cracks hence we are planing to replace the Tyre with new one.
For removal of existing Tyre we need to cut shell near Tyre to remove old Tyre and insert new Tyre .and install new shell in place of old cut shell.
In order to reduce cutting, edge preparation and welding time we propose to use automatic process for cutting as well as welding.
our equipment
We were exploring welding process which can weld the joint while kiln is stationanary and the welding machine shall go round the kiln shell and carry out welding. Flux cord wire with CO2 shielding.

Kiln shell thickness is 35 mm and the kiln diameter is 4750 mm internal diameter and od is 4820 mm. Marerial Boiler quality carbon steel

Can FCAW be used?will shielding be effective in open air-Is any wind shields will be required?what are cautions while welding with co2 shielded flux cored wire.

Thanks
