Multiple panel sheet like three

four even five sheets spot welding process is usually exist in white car body frame

when we use regular parameter to weld

it is hard to achieve the good spot welded joints and defects such as splash

spur and through holes comes out during welding

thus lead to wasting cost and time in production.While the hot forming sheets is widely used by the motor factory

non-splash

well forming joint is hardly achieved by the single pulse parameter process.For such spot welded joints of multilayer plates containing thermoformed plates

spot welding controllers based on BOS6000 software are used for multi-pulse spot welding process parameter tests.By metallographical

BOS6000 UIR Curve

production line feedback

the welding joints with reliable welding spots and low splash rate can be obtained by using the multi-pulse spot welding process.
