introduction：The working principle of argon tungsten arc welding is adopted， It uses the arc burning between the non-melting electrode tungsten rod and the weldment as a heat source，The stainless steel plate is self-fused to form a weld。 The plate and arc zone and the molten stainless steel are protected by argon gas，Isolate it from the air。Because argon is an inert gas，It does not interact chemically with metals，It does not melt into metal，Therefore, oxidation of weld metal and burning of alloying elements can be avoided。The welding process is simple and easy to control。For this reason, we designed our own electronic control equipment，Make the weld surface smooth after welding、No secondary processing required，Just polish，Can achieve bright without trace，And no weld can be found。Welding in progress

introduction： bearing[bearing:bearing（“Bearing”，Japanese person“Axial receptor”）It is a part that holds and reduces the friction coefficient of load during mechanical transmission。Can also be said，When other parts move relative to each other on the shaft，A device used to reduce the coefficient of friction during power transmission and to keep the center of the shaft fixed。]After pressing into the angular contact ball bearing, it should rotate flexibly without blocking。If there is obvious rotation is not flexible，It means that the size of the shaft is too large，Tolerance to be reduced。If the bearing is pressed into the shaft, the hand rotation is obvious“Shasha”A sense of，It may be that the tolerance of the shaft is too large or the roundness of the shaft is not good。So in control well
