範囲内にあるのがよい。[0008] In the above, the depth of the groove is 0.3 to 1.5.
The reason why it is limited to mm is that if it is less than 0.3 mm, the gas and flux residue generated during brazing will not be removed sufficiently.
This is because if it exceeds 1.5 mm, there will be a shortage of brazing material and the groove will not be filled with the brazing material after brazing, resulting in insufficient bonding strength. The depth of the groove is preferably in the range of 0.5 mm to 1.0 mm.

ある。[0009] The reason why the interval between grooves is limited to 5 to 30 mm is that if the interval is less than 5 mm, there will be a large number of grooves, and there will be a shortage of brazing material, and the grooves will not be filled with the brazing material after brazing, resulting in insufficient joint strength. However, if it exceeds 30 mm, gas and flux residues generated during brazing will not be able to escape sufficiently.
【００１０】溝の横断面形状は、半円形、台形等にする

Almost vertical means not only completely vertical, but also 4 degrees from vertical.
This also includes a state where the vehicle is tilted less than 5 degrees.
