Direction welding be located at the group between the connector of perforated inner and perforation inner wall to gap, better than in the connector for being located at perforated outer
Direction, welding be located at perforated inner connector and perforation inner wall between group to gap, even identical welding parameter, weldering
It connects direction and also has a certain impact to welding result；The solder yield of embodiment 1,2 is higher than embodiment 5,6, and embodiment
1,2 face of weld is very smooth, and the welding surface of embodiment 5,6 then have it is a small amount of uneven, the aperture of perforation be 10mm,
When the diameter of connector is 9.8mm, select 6# nozzle that there can be better welding effect；The solder yield of embodiment 1,2 is better than
Embodiment 7,8, and the molding situation of the face of weld of embodiment 1,2 is better than embodiment 7,8, it can be seen that embodiment 1,2
Welding parameter setting is better than embodiment 7,8.
