China Spiral Welded Steel Pipe Piles Suppliers, Manufacturers, Factory

Product Details

spiral welded steel pipe piles The dry extension length of the welding wire, that is, the extension length of the welding wire between the conductive nozzle and the arc generated by the workpiece.The longer the dry extension, the lower the arc voltage;The shorter the dry extension.

The dry extension length of the welding wire, that is, the extension length of the welding wire between the conductive nozzle and the arc generated by the workpiece.The longer the dry extension, the lower the arc voltage;The shorter the dry extension, the higher the arc voltage.In general, the length of dry extension should be controlled in 19 ~ 25.Between 4 millimeter advisable.If the length of dry extension is less than 19 mm, the arc voltage increases, the resistance heat of the wire sheet increases, the wire feed is blocked in the conductive nozzle due to the increase in resistance heat, slowing down the wire feed speed, and the resistance heat increases, the wire core particles fine, also can cause the drop in self-protection pressure and condensation pool rapid generation of pores.If the dry extension is greater than 25.4 mm, arc voltage decreased, often accompanied by broken welding wire, wire top, wire phenomenon.Generally, the dry extension length of welding wire is less than 19 mm, which often occurs in the position of flat welding and vertical welding;Dry extension length greater than 25.4 mm, easy to occur in the position of overhead welding.The length control of the welding wire is very important to ensure the welding quality.
