Welding Procedure

Cut appropriate number of windows on sweep inside radius to expose inside of outer radius.

Clean dirt, grease and debris from all surfaces to be welded. Grind if necessary. Choose appropriate wire type and diameter compatible with the job requirements and available equipment. Select Argon/Oxygen mixture at 35CFH. Preheat and Interpass Temperature: 200 to 250F.

Deposit single layer with weave pattern working in a vertical up position.

Some check cracking may occur, which is usually not detrimental to weld integrity or to the performance of the deposit.

Complete all repairs.

Slow cool to room temperature.

Finish machine or grind if required.

Replace windows and place in service.
