【STL-150】
Laser welding of pulse YAG laser covering/welding equipment
Cases
Use coating to prevent protection
The use of WC, TiC, Cr3 C2 and other wear-resistant, heat-resistant, burning sticky, corrosion-resistant, resistant to oxidation of the material coating, can protect the mold, mechanical parts, tooling, etc., to extend its life.
Before and after coating comparison
Experimental conditions Specimen: SKD-61 Melt metal: ADC-12 (680 ° C) Immersion in molten metal at 30 RPM
Compared with the untreated specimen, the amount of melt loss after coating is only 1/10
1Application
Aluminum die-casting mold
Extend service life by coating
2Application
Use a coating manipulator to coat the casting mold
Prevent mold melting, burning sticky
Repair with surfacing
Through the surfacing to repair molds, mechanical parts such as scratches, bite mold, wear, corrosion, pinholes and processing errors and other defects.
Workpiece : Injection mold ( mold cavity as a whole ).
Problem : Product glitches ( TIG welding has an effect on etch ).
Processing methods : Surfacing ( no heat, corrosion will not be destroyed ).
1Application
Mold without demolition, in the injection molding machine can be on the burrs of the parting surface for surfacing repair, and then use a small grinding machine, rasp, Whetstone and other parts of the welding on the finishing.
To prevent the emergence of burrs, the mold parting surface repair
2Application
Surfacing Repair of Automobile Aluminum Ring Pinhole
