Description

Technical Field

[0001] The utility model relates to the field of welding, and more specifically, to a stainless steel pipe welding device. Background Art

[0002] Stainless steel pipe is a hollow long strip of steel made of stainless steel material. It has excellent corrosion resistance, high strength, durability, beauty and easy cleaning. It is widely used in decoration, liquid or gaseous raw material transmission and other fields. Although the length of stainless steel pipe can be customized according to needs, for the convenience of logistics, storage and use, stainless steel pipe is usually a standard specification of 6 meters when it leaves the factory. When some stainless steel pipes with specifications exceeding the standard are needed, two stainless steel pipes are often welded together.

[0003] Most of the existing stainless steel pipe welding is manual welding, which has high work intensity. There are also some welding devices, but most of them also need workers to assist in fixing the stainless steel pipe. Moreover, most welding equipment is not convenient for adjusting the angle of the steel pipe after fixing the stainless steel pipe. It is necessary to adjust the angle of the stainless steel pipe after welding a certain range and weld the remaining position, which is inconvenient.

[0004] Therefore, a solution needs to be proposed to solve this problem. Utility Model Content

The rotating stainless steel pipes are convenient for the laser welder 2 to weld them. After welding is completed, the electric push rods 24 on both sides drive the push rods 9 on both sides to reset. At this time, the intermittently moving rotating frame 7 will send the welded stainless steel pipe to the discharge port 4, and the stainless steel pipe will be discharged through the discharge port 4.
