FRONT CAR FRAME WELD-CONNECTING STRUCTURE WITHOUT CO2 WELDING

摘要

The present invention relates to a front vehicle body structure of a vehicle junction , in particular A-pillar of the vehicle front assembly Composition by improving the vehicle body so that the closed end side body structure is not generated in the main section of the weld line in the binder part , preclude the use of CO2 gas welding , and one to form the vehicle body only by spot welding , and the front vehicle body structure without a CO2 welding and bonding and an effect which can lead to collapse and modular part of the working process to reduce the number of parts required , yet the vehicle body welding process line through this structure to achieve a vehicle body rigidity increase and cost reduction and weight reduction of the vehicle body .
