For steel structure manufacturers, the material must be pre treated before cutting. It affects the normal operation of the next process. In this way, cutting speed and welding quality can be improved.
In the process of cutting, marking and welding, the surface protective layer and rust must be removed. In the process of plate cutting, there are a lot of welding contour lines and subsequent process marks that need to be marked and positioned. At the same time, it will also make the surface marking blurred
At present, the commonly used method is to install the sand blasting device on the cutting machine. This method is to spray fine sand at high speed on the cutting and marking surface, so as to clean the metal surface. In the later process, it can clean the welding surface more or less. In the welding process, it will also lead to excessive fillet weld, resulting in unpredictable deformation and subsequent surface position deviation, resulting in the adverse consequences of high production cost. This speed can only meet the requirements of cutting, but at present, the speed of powder jet scribing, plasma arc scribing and ink jet scribing has reached 20 m / min. Obviously, this method can not fully meet the technological requirements of high-speed cutting There are many ways to solve these problems. But now the sand blasting technology can only work at a speed of 4 m / min, and the surface cleaning rate is 75%.
