At present, the supercharger has been the industry to achieve friction welding production, turbocharger disc and shaft welding as early as 60s has begun. Friction welding has become a bright spot in the automotive industry, and even affect the locomotive, ships and other industries have to follow the promotion.
The friction welding is solved when casting superalloy K13 turbine disk structure and steel shaft friction welding quality problems, finished behind the complex and cumbersome turbocharger mechanical connection structure of history, greatly improve the product quality and mechanical efficiency, to keep up with the development trend of the world.
Due to the characteristics of the structure, the axle as an important part of the car. Long rod and cross section changes, bring convenience to the manufacturing process, the radical bar in the horizontal forging machine is more expensive on the multi station local upsetting forging manufacturing overall, many supporting horizontal forging machine factory does not have the conditions, the use of free forging, bar drawing, and then head into die forging the shape, complex process of low efficiency, easy to fold and forging defects, even unable to repair waste.
This product adopts the forge welding structure is the most reasonable and should be the first choice of friction welding. Harbin Welding Institute use their strong technical reserves, to solve the phi 30mm45 steel axle friction welding technology and welding inspection and a series of practical problems, to achieve the performance index of the product design, the micro Hafei truck axle realizes the friction welding production of all, has achieved great economic benefits.
