Overall shot blasting after welding can, first, eliminate welding internal stress and avoid frame deformation and cracking caused by stress concentration after long-term use; second, improve paint adhesion, prevent the paint film from peeling off, and greatly enhance the anti-corrosion durability of vehicles in marine salt spray and high-humidity rainy environments.
Why does Jianxing perform overall shot blasting treatment on semi-trailers after welding? What specific performance improvements can it bring?
