Flash welding. As with butt welding, flash welding is a method in which the ends of the workpiece are pressed together and welded. It is used for welding thicker workpieces such as heavy anchor chain, rails and pipes. The process is most often used for welding of steel but also for nickel, aluminium and titanium alloys.

grinding. After edge trimming, the remnant part is removed during a low-speed process of the rough grinding (Fig. 5). Based on the assumption that the depth of the damage created during this process may relate to edge chipping, the extent of the damage after rough grinding was examined.

Warmth is inevitable with grinding -- it's a friction process, after all, and friction creates heat. As we mentioned in the blog, though, the problem comes with very high temperatures maintained for long periods. You could stick an instant-read thermometer in your finished flour and compare it to the temperatures we cited for commercial stone ...

In the method and the device, a gas stream is divided into three partial gas streams. The first partial gas flow conveys the ground material into the grinding and friction space of a mill (26), while the second partial gas flow circulates around the friction space in the mill. The third partial gas stream is connected to the outlet side of the mill and receives the ground and dried ground ...

Deflashing: The flash line, a ridge left by the forming dies, is removed as balls roll between heavy, cast iron plates. Soft Grinding: Similar to deflashing, except that a grinding stone is used to improve precision. Heat-treating: Carbon steel balls are next carburized and hardened. Heat treatment imparts the desired hardness and case depth.

Most of the times, flash-butt welding is used for this purpose. In comparison to the alumino-thermic welding process, this welding technology has the advantage that no foreign material is introduced into the welded joint. In particular when a high grade rail steel is used, the discontinuity in the rail steel can be reduced to a minimum.
