Anti-penetration and avoidance of non-penetration in welding positioner

Welding specification for welding positioner

Correct selection criterion of welding positioner is an important guarantee to prevent welding penetration and to avoid non-penetration, and the inaccuracy of criterion can also cause blowhole.

The penetration of 3mm dial automatic welding is very close to the limit of non-penetration. When the penetration is less than 1.5mm, the phenomenon of non-penetration will appear. When the penetration is less than 2.0, it is easy to penetrate, and the range of penetration change is less than 1mm. Therefore, the welding specifications are strictly limited.

Several specifications for welding wire of 1.6 are represented by current: main weld current I1 = 160A, 180A, 200A; sealing bottom welding current I2 = 220A, 240A, 260A, 280A. For a specification, the normal penetration can not be guaranteed because the penetration of the main weld and the seam bottom weld does not intersect. The two specifications need to produce the phenomenon of welding piercing.

Because the 3mm thin plate zidognh adopts the small specification, the required stability must be very high, otherwise it will cause the phenomenon of penetration or non-penetration, the weld formation will deteriorate, and the defects such as porosity may occur. We require that the fluctuation range of current be controlled within (+10A) and the voltage be controlled within (+2V), so that satisfactory results can be obtained.

Welding positioner involves the user's concept of equipment and equipment, as well as considering the different uses for hand welding and automatic welding. When selecting and designing the welding positioner, besides the main positioning freedom, we should consider increasing the auxiliary positioning freedom. For large welding, it can increase the lifting motion freedom, such as the United States and Germany mentioned above.

In addition, due to the simple distribution of welds, ship welding requirements for most and important welds in some weldments can be solved by using one degree of freedom of rotation, while flat fillet welding can be carried out for a small number of non-important welds. In order to simplify the cost of equipment, single degree of freedom or functional degradation can be considered in the process. Welding positioner, that is, single rotary positioner. According to the requirements of use, it can also increase the degree of auxiliary freedom. For example, lifting and tailstock movable and so on.

In order to meet the technological requirements of the welding station, some degrees of freedom of the welding positioner have nothing to do with welding. In addition, considering the design and stability of the welding station, two or more welding positioners are designed in combination, which results in a variety of position transformations and combined multi-degree of freedom welding positioner products.
