Door and Window Industry
Handheld laser welding has the advantages of firm welding, beautiful weld seams and low deformation. Meanwhile, welding does not require polishing or grinding, is easy to operate, and does not need a special operation certificate. It is simple and convenient for users to recruit workers during installation and welding. (Stainless steel doors and Windows, various small hardware parts)
Seamless welding of stainless steel/aluminum alloy door frames
| Comparison Items | Traditional Argon Arc Welding Solution | Laser Welding Solution |
|---|---|---|
| Thermal deformation | ＞2mm/m | Small deformation (straightening process eliminated) |
| Welding speed | – | 1.5m/min |
| Welding depth | – | 1.2mm |
| Welding wire type | – | ER4043 welding wire (for aluminum alloy) or ER308 welding wire (for stainless steel) |
| Post-processing needs | Requires straightening + polishing, low efficiency and high pollution | No polishing needed (welds are naturally formed in silvery white, saving 30% post-processing cost) |
| Efficiency performance | – | Welding time reduced by 60% (actual test by a anti-theft door factory) |
