Procedure

• Initially the damaged curved surface area profile is gouged out using Lotherme 802.
• After gouging the area is grinded using grinding machine in order to take out all the carbon present inside the CSA..
• Preheating is done to 200 degrees and checked using thermal chalk.
• The initial welding is taken care using Lotherme 701. Since it seals all the impurities.
• The final welding is completed using Lotherme 703. Pure nickel electrode arrests all the cracks and give perfect finish.
