1, D507 welding rod is selected for defect repair welding of carbon steel castings (WCA, WCB, WCC, LCB, etc.).

2, For defect repair welding of stainless steel castings, CF8 selects A102 electrode; CF8M adopts A202 welding rod; A202 is selected for cf3m and CF3, A132 electrode is selected for cf8c.

3, A102 electrode shall be selected for defect repair welding of high temperature steel castings (wc6, wc9, C5, etc.).

4, CA15 is the casting grade of alloy steel 13Cr.

5, No. 1 internals: 13Cr; 2 internals: 304; No. 5 internals: Double Stellite; 8 internals: single Stellite.
