Welding positioner is mainly used in the manufacturing industry, mainly in some construction machinery, which is used more frequently. It is mainly used for circumferential welding and can be used with other machines. It can be applied in a wide range of fields and has good welding performance. With the increasing demand for welding, there are many different types of welding, and there are more and more models. So how to choose the model? Let's have a look.

1、工件適用原則由于建筑機械不同結(jié)構(gòu)間的外形差異大，焊接時的變位需求也不同，因此根據(jù)焊接結(jié)構(gòu)的結(jié)構(gòu)特點和焊接要求，選擇適用的焊接變位機。

1. Due to the great difference in shape between different structures of construction machinery and the different displacement requirements during welding, the applicable welding positioner is selected according to the structural characteristics and welding requirements of the welding structure.

2、方便的焊接原則根據(jù)手動焊接作業(yè)情況，選擇的變位機應(yīng)將被焊工件的任一焊接移動到平焊或船焊位置，避免立焊和背焊，保證焊接質(zhì)量。

2. Convenient welding principle: according to the manual welding operation, the selected positioner shall move any welding of the welded parts to the flat welding or ship welding position, so as to avoid vertical welding and back welding and ensure the welding quality.

3、可選變位機進(jìn)行環(huán)焊時，應(yīng)根據(jù)焊接物的坡口考慮轉(zhuǎn)速，該速度應(yīng)在變位機轉(zhuǎn)速調(diào)節(jié)的范圍內(nèi)，并對工作臺運行上的穩(wěn)定要求，是否能滿足整個工藝的加工要求。

3. When the positioner is selected for ring welding, the rotation speed should be considered according to the groove of the weldment. The speed should be within the range of the rotation speed of the positioner, and the stability requirements on the operation of the worktable, whether it can meet the processing requirements of the whole process.

4、如果變位機的焊接物整體的外廓上的尺寸比較大，則考慮到工作臺的傾斜，或傾斜的角度能夠滿足焊接物的焊接位置等，或者在傾斜的角度與焊接物發(fā)生接觸的情況下，在選擇工作臺時，距地面的間隙變得更大，保證焊接整體的加工要求。

4. If the overall size of the positioner's weldment is large, then considering the tilt of the worktable, or the tilt angle can meet the welding position of the weldment, or in the case of the tilt angle contacting with the weldment, when selecting the worktable, the gap from the ground becomes larger, so as to ensure the processing requirements of the whole welding.

5、易操作原則可靠，開放性好，操作高度低，選擇緊湊的焊接變位機，便于工人操作和變位機的配置。如果焊接構(gòu)造物的變位機的焊接作業(yè)高度高，作業(yè)者可以用墊子焊接，也可以通過安裝液壓升降臺進(jìn)行高度位置調(diào)節(jié)。

5. Easy to operate principle, safe and reliable, good openness, low operating height, select compact welding positioner, easy for workers to operate and positioner configuration. If the welding height of the positioner of the welding structure is high, the operator can weld with a cushion, or adjust the height and position by installing a hydraulic lifting platform.

以上就是焊接變位機在選擇機型時應(yīng)該考慮的因素，根據(jù)不同的需求進(jìn)行選擇，就能較大化的發(fā)揮好機器的性能，手動焊接時要考慮到現(xiàn)場的施工情況，結(jié)合自己的情況進(jìn)行選擇，才能保證施工過程的順利進(jìn)行。

The above are the factors that should be considered when selecting the welding positioner. According to different needs, the performance of the machine can be brought into full play. When manual welding, the construction situation on site should be taken into account, and the selection should be made in combination with one's own situation, so as to ensure the smooth progress of the construction process.
