To make a cone, we change the shape and dimensions of each workpiece in accordance with the specified parameters. We heat a part of the pipe in an induction heater. Next, we send the workpiece to a rotary forging machine to give it a conical shape, after which the cone is additionally pressed in to make the tip lanceolate.
We begin the spiral winding stage with automated welding equipment. The specialists also check the important elements of the workpiece:
spiral winding steps;
the slope of the spiral.
The accuracy of winding and checking the seams affects the efficiency of the product: in case of poor-quality welding and inclinations, the ground will scroll, enter the ground with increased pressure and it will be impossible to reuse it. After checking the spiral, a specialist will clean out burrs and excess incandescence.
On the automated welding equipment, welding of the flange begins. The welding process takes place on a robot: with its help it is possible to apply the required amount of mixture and weld at the junction of the pipe and flange. Thus, it is possible to reduce the human factor to a minimum and improve the quality of work. At this stage, maximum accuracy is required: if you weld the flange poorly and do not check the seam, there is a high probability that the flange will come off the pipe and you will not be able to screw it into the ground.
