Advertising Signs Welding

Stainless steel letters, metal logos, outdoor billboards - laser spot + continuous welding, strong and smooth.

Background

The advertising sign industry needs to weld 0.8–1.5mm stainless steel letters, galvanized sheet brackets, and aluminum composite panels. Traditional spot welding produces large, rough welds; TIG welding causes deformation and requires polishing. Laser welding does both spot fixing and continuous sealing with a clean surface.
