Abstract
This paper introduces the characteristics and application difficulties of aluminum alloy spot welding process.In order to reduce the manufacturing cost of aluminum alloy spot welding,this paper designs a new method to improve the welding points after each grinding by using the compressed honeycomb mold to make the electrode surface form a specific shape,and using the compressed electrode to carry out aluminum alloy spot welding.The research results show that for the 2 mm+2 mm 6 series aluminum alloy plates,by using the electrode cap with an arc size of R100 mm on the front section,with appropriate process parameters(welding current 42.5 kA,welding pressure 6.8 kN,welding time 100 ms,and pressing pres-sure 7 kN),when the depth of the pressing die pit is 0.5 mm,the width between the dies is 0.4 mm,and the width of the bulge is 0.2 mm,at least 128 spot welding points can be obtained after grinding,And with the increase of the number of welding points,the strength of welding points shows an upward trend.This research provides a reference and optimization direction for the development of aluminum alloy spot welding technology in the manufacturing industry.关键词
