[0002] After spot welding and arc welding the vehicle body rails, common issues include burrs, spatter, and poor arc welds. These defects can affect the overall appearance and quality of the vehicle body components, necessitating manual grinding and touch-up welding. Grinding primarily removes burrs and surface irregularities created during welding, ensuring a smooth weld, thereby improving appearance quality and painting accuracy. Touch-up welding addresses poor welds or leaks, repairing defects by re-welding to ensure weld strength and sealing.
