| Abstract: | With the application to mould modification and repair machine (MODEL GM-3450(B)), various alloy powders are used in the repairing experiment on cold-work mould. You can get the spot welding layer for repair, which has excellent adhesion and extremely small HAZ at the welding area. It has been verified that mini-area pulse resistence depositing welding technique is a useful means of cold-work mould repairing. |
