MICRO 2X16 III控制器.pdf The resistance welding process made tremendous progress in the early 90’s with the introduction of current regulation. Now is the turn for the welding force to be mastered perfectly. Problems associated with unstable force values, such as: 􀀩 sticked spots 􀀩 expulsions (splatters) 􀀩 sticked electrodes 􀀩 irregular nugget diameters 􀀩 marked sheet can be reduced significantly. Excellent force repeatability can be achieved and documented, both for welding and tip dressing. Fast and accurate force management opens up new possibilities, such as: 􀁘 Force profiles 􀂪 Reduction of porosities and cracks in aluminum welding 􀂪 Better sheet contact 􀂪 Increased weld quality on carbon steel 􀂪 Better weld quality on high thicknesses 􀁙 Force ramps 􀂪 Increased weld nugget density 􀂪 Better metallurgical structure of weld nugget 􀂪 Better electrode contact through elimination of glue, filler paste, joints,etc... 􀂪 Control of sheet contact 􀁚 Perfect synchronization of force and current profiles 􀂪 Cycle time reduction 􀂪 Increased weld quality FORCE REGULATION FORCE PROFILES Force regulation also allows cycle times reduction: |
