Additional Notes

**When base metal temperature is below 32° F, the base metal shall be heated to a minimum of 70° F and shall be maintained as the

minimum interpass temperature during welding.

**Welding shall not be done when ambient temperature in the weld area is lower than 0° F

***When using Non-Steel Backing, backing shall be removed and backgouged to sound metal and back welded
