| Abstract: | The failure of spot welding electrode made of TiB 2 /Cu with TiB 2 content of 1.5wt% has been studied during spot welding of zinc coated steels . Results show that the service life of the composite electrode is 4 times that of the conventional CuCrZr electrode. The failure of the composite electrode during spot welding of zinc coated steels is alloying on the surface of electrode tip, together with little final turnover, sticking and pitting, while the mushrooming dose not appear, therefore it is a better material used as spot welding electrode. |
| Keywords: | electrode spot welding TiB 2/Cu composite zinc coated steels |
