 Kohler brand of special cold welding repair: 
 Cold welding to make up the conventional methods can not achieve the purpose, or inconvenient to achieve the purpose of a repair method, mainly on the need to change, recovery equipment, the workpiece contour, size, or change to achieve the restoration of its original function of a job. 
 In the daily maintenance of equipment, some expensive, especially thin, the device under alternating stress on the surface by corrosion, scratches and other damage and be unable to perform routine maintenance. Because there will be varying degrees of deformation, cracks and other obvious damage and brittle, with internal stress and other hidden damage. There are some jobs because of environmental equipment, workpiece size is too large, too long time to repair, replacement of the cost of higher factors, it will use cold welding repair. 
 Cold welding of metal defect repair features: 
 1, construction safety, without any negative impact on workers 
 2, field repair, not dismantling or disassembly of the case is particularly suitable for long time 
 3, good mechanical properties after repair may be machined 
 4, the application of a wide range of conductive wire for all common wire, to choose according to different combinations of different materials 
 5, the real molten metal repair, high strength 
 6, can ensure that the repair parts to repair the 40 degrees Celsius to ensure that body parts from harm 
 7, the solder layer thickness can be precisely controlled in the 0.02-3 mm 
 8, for a variety of metal restoration 
 9, can be used to achieve different metal welding surface modification
