Drive shaft parts may show wear, that how to deal with? The traditional approach is still valid, feasible and simple, we can try to operate:

Domestic for drive shaft wear usually chooses is welding, insert sleeve, stamping and other measures, but when the material is 45 steel (hardened and tempered disposal), if only the selection of welding disposal, will then have the welding stress, in heavy load or high-speed work condition, may appear crack even cracking appearance in the shoulder, if choose to stress annealing, it is difficult to operate, and long processing cycle, high maintenance costs; when the raw material is HT200, cast iron welding is not ideal.
