Further improvement as a kind of deep hole tube sheet of the present invention exterior angle welding gun: described welding torch seat comprises the installing sleeve and porcelain mouth branch sleeve that connect side by side, the axis of porcelain mouth branch sleeve and the axis of installing sleeve are that angle is arranged, welding torch seat is fixed on connecting rod front end by installing sleeve, and porcelain mouth is fixed on welding torch seat by porcelain mouth branch sleeve.
Further improvement as a kind of deep hole tube sheet of the present invention exterior angle welding gun: it is inner that described eccentric mounting is fixed on rifle body by dog screw.
beneficial effect
Welding gun of the present invention is deep hole tube sheet exterior angle welding gun, and the structure of welding gun is simple, reasonable in design, easy to manufacture, easy to use, and welding gun, when passing in and out pipe plug opening, only need stir regulating block thus the bar that is rotatably connected utilizes eccentric center principle that soldering tip is taken in rifle body.Stretch into after bobbin carriage puts in place at rifle body and again rifle head Unscrew is regulated tungsten electrode and tube sheet, heat exchanger tube distance, then start welding, tested by reality, welding quality is better, is convenient to promote.
