as shown in fig. 1 to 4, the positioning tool for welding and forming the steel sofa leg is shown, and before the positioning tool is specifically explained, for convenience of understanding, the basic structure of the sofa leg is first specifically explained as follows:

the positioning tool is mainly applied to welding of splayed sofa feet, specifically, as shown in fig. 4, each sofa foot comprises a main beam 11 and two side beams 12 which are respectively arranged on two sides of the main beam 11, wherein an included angle is formed between each side beam 12 and the main beam 11, in order that the main beam 11 and the side beams 12 can be smoothly butted when being butted, the butting surfaces of the main beam 11 and the side beams 12 are oblique surfaces, and during welding, the two oblique surfaces are welded to be jointed.

It should be noted that the back side of the main beam 11 has a mounting hole 111 for fixing and mounting the main beam 11 and other components such as a sofa.

Meanwhile, in some sofa legs, a pin 13 is further arranged at one end of the side beam 12 opposite to the main beam 11, and one end of the side beam 12 opposite to the main beam 11 is of an arc-shaped notch structure so as to be attached and welded with the pin 13.
