Area of Science:

• Materials Science
• Manufacturing Engineering
• Laser Technology

Background:

• Laser shaping technology is increasingly applied across various fields.
• Laser repair technology offers benefits such as extended product lifespan, reduced production costs, and resource recycling for micro-explosive products.
• Research on laser shaping for micro-explosive product repair remains limited, with a focus primarily on aspheric surface shaping and testing.

Purpose of the Study:

• To investigate the application of laser shaping technology in repairing explosive bridge films.
• To enhance the ignition performance and prevent damage to micro-explosive components through laser repair.
• To compare laser shaping and non-shaping repair processes for metal films.

Main Methods:

• Repairing metal films using both laser shaping and non-shaping processes.
• Analyzing laser-damaged film surfaces before and after shaping.
• Investigating the influence of laser energy parameters on the microstructure and ignition properties of repaired regions.
• Simulating temperature field variations to determine an optimal repair scheme.

Main Results:

• Damage to the explosive bridge film can be repaired using heat flow (non-shaping) and vaporization (shaping) methods.
• Laser shaping repair is effective in improving the microstructure and ignition properties of the repaired region.
• Controlling process parameters enhances repair quality and reduces production costs for bridge films.

Conclusions:

• Laser shaping technology provides an effective method for repairing damaged explosive bridge films.
• Optimized laser shaping processes can significantly improve ignition performance and component reliability.
• This technology contributes to cost reduction and resource sustainability in micro-explosive component manufacturing.
