Deposition welding in the tool and mold making industry
Damage, wear, design changes – there are plenty of reasons why a tool must be modified or remanufactured.
The use of lasers can often prevent the need for refabrication, helping you meet deadlines and keep costs down.
Whenever material must be deposited, this can be done by a laser with extremely high precision. The welder guides the added material by hand in the form of thin wires, observing the weld point under a microscope. Protective gas and laser pulses are triggered with a foot pedal. This concentrated activity requires the best in ergonomic equipment, and a well-trained welder.
All metals commonly used in tooling can be processed with a laser; whether you are using electrode copper, beryllium copper, aluminum or tool steel. The additional material is selected independently of the base material in order to achieve perfect welding results, even in crack-prone alloys.
The very low heat introduction of the laser beam provides numerous advantages:
- Welding can often be done without preheating
- Precision material deposition requires only minor refinishing
- All processes for refinishing are possible
- There is almost no loss of hardness
- Scorching indentations are avoided
- Welding is possible in cavities
