Equipment features
Laser welding for metal channel letters
The HODA channel letter laser welding machine serves the making of metal channel letters, letter shells and sign components. A letter is built from a face, returns and connectors, and the welds sit on edges, corners and curves. Adjustable pulse and spot settings put the energy exactly on the joint, and the process links to the later grinding and polishing steps.
Built Around Letter Joints
- Face, return and connector joints organized as the work
- Handles the varied shapes and scattered seams of letter making
Pulse Control, Low Heat Input
- Pulse width, frequency and spot set the weld point
- Process built around sheet thickness and joint location
Straight, Curved & Narrow Areas
- Workpiece repositioned letter by letter
- Narrow corners and deep letter shells checked on a sample first
Adjustable Spot for Detail
- 0.2–2 mm spot range for different joint sizes
- Settings combined with material, thickness and weld layout
Positioning & Visible Face
- Fixturing keeps face and return in assembly relationship
- Visible-face finish and polishing included in the process plan
Mixed Sign Production
- Different fonts, outlines and letter sizes on one machine
- Fits into existing cutting, bending and surface-treatment flow
Applications
Where the letter welder fits
For sign workshops producing metal channel letters and custom signage in small batches.

Materials
Metal letter materials suitable for laser welding. The process is set by the actual grade, thickness, coating and finish state; painted, plated or composite letters should be tested with a real sample.
Configuration & support
Choosing power and worktable
Sample letterTake one letter with straight, corner and curved sections as the process reference.
Access checkHead reach, fixturing and viewing checked against the real geometry.
Finish planGrinding or polishing after welding included in the confirmation.
Power & tableSelected by material, thickness, maximum letter size and station layout.
Large letters need support and moving space; small letters and narrow corners need reach and observation. Both are confirmed on the actual letter shape.
