Projection Welding Failure. Any or all can or will cause havoc with push off tests. The plating should have a lower melting point than the base alloy.
EPRI Palo Alto CA. ExpulsionBurn-Through Issues with high electrode follow-up high current and welds too close to the edge may cause the expulsion of molten metal during welds. Failure Modes and Effects Analysis FMEA of Welded Stainless Steel Canisters for Dry Cask Storage Systems.
Iii ACKNOWLEDGMENTS The following organization under contract to the Electric Power Research Institute EPRI prepared this report.
Weld failures can result from weld defects such as cracking or inclusions but there are a number of other issues in the welding operation that can also contribute to the problem. The goal of course is. Tin plating is squeezed out and allows base copper on both sides to come in contact and form a strong copper-copper solid-state bond see Figure 5. So this should be.
