The welding phase is perhaps the most important part of the production line
. There are several welding techniques employed, with the most common being high-frequency electric resistance welding (ERW) and submerged arc welding (SAW).3. Automation and Sensors The latest advancements in flat straightening machinery feature automation technology. This includes sensors that monitor the surface and curvature of the metal in real time. By employing feedback loops, the machine can make immediate adjustments to ensure optimal straightening. This technology not only improves the quality of the output but also increases operational efficiency.
After extrusion, the freshly formed copper pipes undergo an annealing process to relieve internal stresses and enhance ductility. Annealing ovens use controlled heating and cooling cycles, ensuring that the pipes are soft enough for bending and installation. Once annealed, the pipes proceed to the tubing stage, where they are cut to length and undergo quality inspections. Sophisticated laser cutting machines are often utilized for their accuracy and speed, minimizing waste and maximizing efficiency.
