When choosing welding positioner, there are three main principles: 1. Choosing suitable workpiece; 2. Welding should be convenient; 3. Simple operation.

Firstly, there are great differences in the shapes of the structural parts when selecting suitable workpieces and different construction machinery, so the demand of the dislocation is different when welding. So we should select the welding dislocation machine according to the characteristics of the welded structural parts, the main requirements of welding and so on.

Secondly,Welding should be convenient. According to the main performance of manual welding in the operation, when we choose the welding positioner, we should choose different welding positions that can turn any welding seam into flat welding, or ship welding, absolutely avoid the phenomenon of upright welding or upright welding, so as to effectively ensure the quality of the whole welding.

Finally,the operation should be simple. It is better to choose a welding positioner with low operation height, safety and reliability, compact structure and good openness, which will be more convenient for the operator to weld, or for the placement of the welding positioner. If the whole welding operation height of the welded structural parts is relatively high, the operator can carry out the pad height. Or the assembly of hydraulic lifting platform to adjust the height of welding.
