Corresponding heating temperature, which is chosen, according to the type of solder and solder flux examines tamping pickaxe matrix in being brazed heating process
Between hard alloy weld tabs, when there is bubbling and cored solder precipitation, that is, stop heating, in brazing process, while observe each hard
Matter alloy weld tabs position need to carry out position in time and repair when having position movement in being brazed heating process under Surface Welding at High Temperature situation
Just；
S7：It keeps：
After being brazed heating, weldering tire fixture is not unclamped immediately, is kept further taking out within 15 seconds to 20 seconds or so workpiece, is ensured solder
It is fully cured, unclamping again fixture after so that hard alloy weld tabs position is consolidated fixes.
Using the present invention of above-mentioned technical proposal, compared with prior art, the feature protruded is：
1. multiple hard alloy weld tabs once can be fusion welded on six different angle acting surfaces on the matrix of tamping pickaxe head.
2. it needs to process technique groove on the matrix of tamping pickaxe head, it so not only need not be complete in tamping pickaxe head matrix surface
Portion covers hard alloy weld tabs, reduces the usage amount of hard alloy weld tabs, reduces cost, and due to the setting of technique groove,
Hard alloy weld tabs is set to be easier accurate positionin and uniform melting welding, the hard alloy weld tabs shape of strip reduces hard alloy
The incompletely formed rosin joint of intermediate position melting welding that weld tabs area is susceptible to when larger closes to form the larger hard of brittleness
Gold solder piece is in stand under load operation, embrittlement phenomenon that rosin joint position is likely to occur.
3. when hard alloy weld tabs is arranged, hard alloy weld tabs outer surface is higher than tamping pickaxe head outer surface of matrix, makes to smash
In operation process, the raised outer surface of hard alloy weld tabs is contacted with working medias such as ballasts pick first, ensures protruding part
Hardness is more than concave position hardness, becomes the wear-resisting working surface in tamping pickaxe head, enhances the wear-resisting property of tamping pickaxe, extend tamping pickaxe
Service life, reduce the use cost of tamping pickaxe.
