All other materials were domestic products of the highest available grade.
The carbon offset microelectrodes with good electrical conduction were obtained finally after implementing 3-step pyrolysis process in a temperature and time controllable quartz-tube furnace (GSL-1500, Kejing Materials, Hefei, China) under inert atmosphere (95% N2, 5% H2, 2000 sccm in total).

Introduction Welding was the one of the key technology of cold rolling strip steel, resistance welding was used generally, its disadvantages were the bigger broken strip rate (2％～3％) and a projecting welding line,when strip steel passed the planishing mill, the strain of strip steel should be released for the surface of rolling free of scrape by welding line,leading to the situation that strip steel can’t be planished and the finished product rate was reduced.Laser welding was a new welding method with many advantages[1～3],at first,the laser welding equipment has good stabilization and repetition,higher precision,reliability,a few maintaince and lighter weight;second,laser welding technology was mature, the better performance index of weld as good as that of base metal is available,the broken strip rate was under 0.5％,the producing efficiency increase 5％-8％;finally,the welding line had lower height and it's not necessary to be cut before cold rolling,the product output and the finished
