Laser welding technology
Technology NewsLaser welding can be divided into pulse welding and high-power continuous welding. Laser welding can make a single weld obtain high-density energy from the laser source. High-speed welding has little effect on the heating and deformation of the weld. The welded joint has high performance and quality, and the weld size of laser welding can…
History of explosive welding
Technology NewsExplosive welding was first put forward by Carl in 1944. He was the first to observe the solid-state welding of materials caused by explosive detonation under high-speed collision, so he put forward the idea of using explosion and ultrasonic technology to weld various metals together. Then philipchuk V of the United States introduced the explosive…
Difficulties in sheet metal stretch forming
Technology News1) In order to ensure the accuracy of the part surface, it is necessary to adopt deep drawing forming with many bulging components, so the thinning amount in the top area of the part arc is the largest, and the thickness thinning amount is easy to exceed the tolerance; 2) The springback after deep drawing…
