Beschreibung
Zusammenfassung:	The utility model relates to a positioning device for welding, which comprises a positioning sleeve and a positioning rod connected into the positioning sleeve. An elastic part is arranged at one end of the positioning rod and inside the positioning sleeve. The positioning device adopting the elastic structure can be automatically positioned, and is simple and convenient to operate, and since a cylindrical pin and a body of the positioning device can be positioned accurately and reliably, separation between the positioning rod and a part caused by part thermal expansion can be avoided. Therefore, the positioning device can meet the design requirements of a drawing, also increases welding efficiency, and can also guarantee quality.
