High-frequency welding H-beam quality problems

High-frequency welding H-beam quality problems According to data, the high-frequency welding H-beam defects occur far less than the hot-rolled H-beam, but this does not mean that it will not produce defects. Therefore, after the finished product comes out, a series of tests are required to check whether the quality of the high-frequency welding H-beam has reached the required standard.
Before testing, we should understand what the standard of high-frequency welded H-beam steel should be: the distance between the splicing seam of the flange plate and the splicing seam of the web should be greater than 200mm. The splicing length of the flange plate should not be less than 2 times the board width; the splicing width of the web should be greater than 300mm and the length should be greater than 600mm. Although high-frequency welded H-beams allow small deviations, they must be calibrated if they are too large.
After the quality is finished, the high-frequency welding H-beams shall be recorded according to the inspection batch. The main record is the size, surface, and weld of the profiled steel. After recording the appearance data, the interior of the high-frequency welded H-beam should also be inspected using ultrasonics and the results recorded.
The quality of high-frequency welded H-beam steel can be improved by some measures, such as: selecting excellent quality raw materials, not using crude products, and paying attention to the small links in the welding process; conducting regular inspections and maintenance of welding facilities; and training operators in skills , improve its working technology, appoint the correct production rules and guide employee compliance; introduce advanced production facilities and production technologies, etc. These methods are practical and commonly used.
No matter what kind of product, quality has always been valued by consumers, so if you want to sell well, quality is the last word.
