CO2 laser is applied to medical equipment welding

2017-07-24 16:38:17
  The probe and lead used for medical devices must be made of different alloys, depending on the ultimate use of the equipment.The welding points must be smooth and without air holes, so that the equipment can be repeatedly sterilized in the high pressure sterilizer.In some cases, medical devices are small and require microscopic welding.OEM components must be connected to hardened stainless steel for biopsy or dental tools.In other cases, the electronic components are compressed in the tool and must be sealed in the equipment to require that the welding smoothing does not damage the component.
Laser welding is applicable to all these devices because laser welding can be smooth and sealed.Laser welding heat is small, welding position can be close to polymer seals, glass metal seals, welding elements, and electronic circuits.It can also be used for welding leads and connecting lines.
  Most of the non-implantable medical tools are 304L stainless steel.It is easy to weld, does not produce cracks, and is not as prone to corrosion in the weld area as high carbon stainless steel alloys.Sometimes with other alloy, such as high hardness like 440 c or 430 stainless steel, sometimes using titanium alloy Ti6-4, as long as the correct welding method and alloy combinations, all of these can be welded.
  Surgical tools, such as biopsy tools, use laser welding to connect the shaft pins to the component, welding the components to the lead.The range of laser welding for dental appliances is extensive, from grinding to the shell of the tool.At assembly time, small blood vessels are welded with laser, and this fine tool requires smooth and consistent welds.Scaffolds, cardiac catheters, and other arterial treatment tools will be assembled by laser welding.To facilitate X - ray inspection, add X - ray opacity on the components.The rigid endoscope is often used in stainless steel tubes and is sealed with a laser seal between the tubes.In most cases, the welds of laser welding are smooth, no stomata, and repeatable welding can be used to require less deformation and high pressure sterilization.
  Pulse YAG laser is the best choice for medical equipment welding.They have high peak power, low heat, and can solve the problems of different alloys. They can be processed with high melting depth.Optical fiber transmission is the most commonly used, because consistent focal spot size and energy distribution can help to fill various gaps with corner and butt, and get a good core diameter when a lot of welding is done.Also, small focal spots remain within 40-60um.Continuous laser and supermodel YAG lasers are the best choice for a large number of fast welding.
