How to use laser welding machine for repairing automotive stamping dies?

1, Basic principles and advantages of laser welding machine
Laser welding machines use the great energy density of laser beams to quickly melt and solidify the welding material, thereby serving the welding function. Laser welding equipment mostly benefit maintenance of automotive stamping moulds in the following ways:
The laser beam's narrow focal diameter, concentrated energy, and exact welding of small areas enable meeting of the very high precision criteria for mould repair.
Low heat input: Laser welding produces a tiny heat input that has minimal thermal effect on the mould substrate and lowers the danger of workpiece distortion.
Good effect of repairs: High weld strength, deep melt pool, strong welding, flawless and attractive weld without any repair marks from laser welding
Great adaptability: Often used for repairing automobile moulds, laser welding equipment can be used for welding various materials, including stainless steel, alloy steel, etc.
2, Application scenarios of laser welding machine in automotive stamping die repair
Common damage in automobile stamping moulds is wear, chipping, cracking, etc. Repairing these damages depends much on laser welding equipment.
Wear and tear repair: The surface of the mould may wear and tear over extended stamping operations, therefore compromising its accuracy and service lifetime. By melting wear-resistant materials, laser welding machines may fix the surface of moulds so restoring their original accuracy and performance.
Uneven tension or material flaws could cause the mould to suffer with corner breakage during stamping. By accurately adjusting the energy and focal point of the laser beam, a laser welding machine may repair the fractured corners and restore the mold's integrity.
Long-term use can cause tiredness or stress concentration to cause mould cracks to show. Through exact welding of small regions, laser welding devices may fix cracks, stop their spread, and increase moulds' service lifetime.
3, Operation Process of Laser Welding Machine in Automotive Stamping Mold Repair
In automotive stamping die repair, laser welding machines operate mostly in three steps:
Damage analysis: First, a base for later repair work depends on an analysis of the mold's damage condition, identification of the type, location, and degree of damage.
Before restoration, the mould surface must be cleaned and treated to eliminate contaminants including rust and oil stains, thereby guaranteeing welding quality.
Plan of design for repairs: Create a repair plan based on the damage scenario including choosing appropriate welding materials, figuring welding parameters, etc.
The repair plan calls for you to fix the mould with a laser welding machine. To guarantee welding quality, exact control of the energy, focal position, and laser beam welding speed is required during the welding process.
Grinding and polishing on the weld seam will help to make the weld seam flat with the surface of the mould and satisfy usage criteria once welding is finished.
