The advantages of laser welding technology in jewelry processing
Laser welding technology is an efficient and precise welding method that uses a high-energy density laser beam as a heat source. This article takes you to understand the advantages of laser welding in hardware processing.
① It can reduce the required amount of heat input to a low level, with a small range of metallographic changes in the heat affected zone and low deformation caused by thermal conduction;
② The welding process parameters for single pass welding of 32mm thick plates have been verified and qualified, which can reduce the time required for thick plate welding and even save the use of filler metal;
③ No need to use electrodes, there is no concern of electrode contamination or damage. And because it does not belong to the contact welding process, the wear and deformation of the equipment can be reduced to a low level;
④ Laser beams are easy to focus, align, and be guided by optical instruments. They can be placed at an appropriate distance from the workpiece and can be guided between tools or obstacles around the workpiece. Other welding methods cannot be applied due to the aforementioned spatial limitations;
⑤ The workpiece can be placed in a closed space (under vacuum or controlled internal gas environment);
⑥ The laser beam can be focused on a very small area and can weld small and closely spaced components;
⑦ The range of weldable materials is wide, and various heterogeneous materials can also be joined together;
⑧ Easy to automate high-speed welding and can also be digitally or computer-controlled;
⑨ When welding thin materials or fine diameter wires, there will be no problem of melting back like in arc welding;
⑩ Not affected by magnetic fields (arc welding and electron beam welding are easier), able to accurately align the welded parts;
Can weld two metals with different physical properties (such as different resistances);
No vacuum or X-ray protection is required;
If using perforated welding, the depth to width ratio of the weld bead can reach 10:1;
Can switch devices to transmit laser beams to multiple workstations
