摘要
Abstract
In welding workshop,multi plate lapping is used to resistance welding usually,but so many uncertainty factors are there in welding process.In order to use less test times to meet production requirements and solve the welding nugget problem of multil-ayered panel lap,the optimizing welding parameter for 3 layer of low carbon steel plate with thickness of 0.8 mm+l.4 mn+l.8 mm was found in this paper.Experimental results show that:the welding current 9.6/8.8/11.1 kA,welding time 5/19/5 cycle,electrode pressure 3 kN is suitable for 3 layer of low carbon steel plate with thickness of 0.8 mm+ 1.4 mm+ 1.8 mm,multiple-pulse welding parameter is appropriate for multilayered panel lap,and diameter of nugget on each layer can achieve 6 mm.关键词
