Detailed Description
The present invention will be described in detail with reference to the accompanying drawings.
The structure of the inner shielding gas rod for laser welding provided by the embodiment is shown in fig. 1-3, and comprises an inner shielding gas rod body 1, a deslagging mechanism and an air inlet rod 9.
The inner protection gas rod body 1 is made of copper. One end of the inner protection gas rod body 1 is provided with an air inlet 3, the air inlet 3 is provided with an internal thread, and the other end of the inner protection gas rod body 1 is provided with a threaded hole. Be equipped with gas passage 2 in one side that interior protection gas pole body 1 is close to the air inlet, be equipped with gas outlet 4 on the interior protection gas pole body 1 lateral wall, gas outlet 4 and air inlet 3 communicate with gas passage 2 respectively.
The inner protection gas rod body 1 is provided with a through groove 5, the through groove 5 is a waist-shaped groove, and the through groove 5 axially extends along the inner protection gas rod body 1. The gas channel 2 and the through groove 5 are sequentially distributed along the axial direction of the inner protective gas rod body 1, and the gas channel 2 is not communicated with the through groove 5. The gas outlet 4 and the through groove 5 are in the same direction, and when the inner protective gas rod is used, the gas outlet 4 and the through groove 5 face the welding line of the welding pipe.
