The preparation of diamond cutting tools in front of the welding include: preparation of the section preparation, preparation of the matrix, and the flux of the pad. A.
1 block preparation
The section has been over grinding arc processing, the welding surface has been the oxidation of the skin, the arc has been in line with the requirements of the process. Next two: first, segment height were grouped according to, to welding saw blade as far as possible round; the second, with acetone or gasoline cleaning section block and allowed to dry, to ensure that the welded.
2 matrix preparation
Matrix, there is a lot of oil (rust, grease), and even corrosion, need to be carefully cleaned, use emery cloth playing to the two planar parts of rust. In the grinding machine to the welding surface grinding, in order to remove the burr, rust, to ensure the welding firm.
3 solder pads, flux preparation
General welding sheet rolling strips, cut into approximately of 0.5 ~ 1.0 cm wide band, the disc into discoid, facilitate the use of the automatic welding machine, with many reported thickness. Such as manual welding, can be used to make the required size of the cut.
In order to make the smooth welding, welding on the contact surface (nodal, matrix and welding pieces) are evenly coated with a layer of silver brazing flux. The purpose is to make the welding jointers contact surface oxide reduction, promote the solder melting, improve welding pieces of the melt flow.
