general light pole after submerged arc welding, the whole joint with eyes passing through a discovery is not straight, even twist, this kind of phenomenon in the street lamp manufacturers in the production of street lights are often happened, and the longer the length of the street lamp light pole, its mouth is likely to twist up and down, the more obvious. The causes of this phenomenon is there are a lot of factors, light pole manufacturer is easy for you to introduce the following points: firstly, from the steel raw material, steel strip coil kaiping later need to use cutting machine to plate according to the size of the mouth up and down light pole requirement to shear, it is important to note that the shape of steel plate after cutting should be isosceles trapezoid, rather than right Angle trapezoid. Many lighting manufacturers for save trouble, ignored part of the link, the only side of steel plate cutting, this is one of the details happened cause problems. Good second, bending, cutting the steel plate after the next step is to roll bending, bending process is a steel plate width by bending die for extrusion, extrusion to half of the steel plate width, and the remaining portion of the width of the repeat the previous action, on the other side of the machine so that the light pole type cylinder came out. At the time of bending point often overlooked by the staff, it is will be send the plate to the mold, plate fluently and lower into the size of the error, that is to say, this link error, the greater the final effect is poorer, after welding. Three, the third part is submerged arc welding, which is through the equipment will be folded the rod tube welding die commissure, after welding the light pole after finishing basic finalize the design, that is, the joint light pole in a straight line or not cannot be corrected.
