Boom-type welding for large molds
The HODA large mold laser welding machine uses a boom-type arrangement that brings the welding head to molds too large or heavy for a conventional worktable. The head and support are arranged around the mold in place, repairing edge wear, chipped areas and local defects on large tooling.
Boom Structure Around the Mold
- Head reach planned around the repair area, not the table
- Suits large, heavy or awkwardly placed molds
Local Defects Only
- Pulsed laser fuses filler at the worn edge, chip or defect
- The whole mold surface is not the working area
Micro Observation
- Microscope assists weld positioning and the fill process
- Small defects on a large mold stay a local operation
Motion Matched to Repair Direction
- Lifting, rotation and horizontal movement combined by configuration
- Structure selected by the defect plane and working angle
Fine Wire & Pulse Control
- Filler wire by power; pulse width, frequency and spot adjustable
- Edge repair and local filling each get their own settings
Links to Maintenance Workflow
- Support, observation, welding and finishing arranged together
- Finishing to target size planned after welding
Machine & repair site
Structure and on-site repair
The boom arrangement and a large-mold repair site — reach and support are confirmed against the actual mold.
Arm reach, travel and support depend on the machine structure and the actual mold layout.
Applications
Where the large mold machine fits
For repair work where mold size, weight or defect position rules out a conventional workstation.
If the mold fits a conventional station, the standard Mold Laser Welding Machine may be the simpler choice.

The boom-type structure positions the welding head around large molds. Access to the repair area depends on the defect location, welding direction and surrounding clearance.
Materials
Mold steels including S136, SKD-11, NAK80, 718, 738, P20 and W302, plus suitable carbon, alloy and stainless steels — assessed for plastic, die-casting, casting, forging and stamping molds.
Configuration & support
Planning the on-site layout
Defect positionWhere the damage sits decides the head approach and support.
Mold size & weightDimensions and lifting decide the boom and support arrangement.
Workshop surveySite photos and mold sizes reviewed before the layout is proposed.
Repair processFiller, welding parameters and finishing arranged with the repair plan.
Mold dimensions alone do not decide reach — the defect position, welding direction and nearby obstructions matter.
