Abstract

The invention discloses a surfacing welding process of a loader bucket. The surfacing welding process of the loader bucket comprises the following steps: flux-cored wire consumable electrode gas protection surfacing welding is utilized; the surfacing welding process standard is as follows: the diameter of the flux-cored wire is 1.58 mm, the welding current is 220-240 A, the arc voltage is 24-26 V, and the CO2 gas flow is 14-18 L / min; consumable electrode CO2 gas protection arc surfacing welding utilizes a semiautomatic or full automatic process, and the surfacing welding speed and the cladding rate are high. The surfacing welding process of the loader bucket can overcome such defects as high failure rate, large maintenance difficulty and low reliability in the prior art so at o realize the advantages of low failure rate, small maintenance difficulty and high reliability.

Description

technical field [0001] The invention relates to the technical field of machinery, in particular to a surfacing welding process for a loader bucket. Background technique [0002] When the loader bucket is used in continuous high-strength conditions, failures such as open welding, tearing, excessive wear, and boring scattering during lifting will occur. This is caused by the use of super-strength material density. The strength safety factor of the bucket Insufficiency is one of the main reasons. In general, the welding of the bucket support will inevitably produce welding residual deformation that cannot be ignored. However, post-welding deformation correction is not economical but also seriously damages its working reliability. [0003] Cracks often occur at the welds between the bucket teeth on both sides of the loader bucket and the guard plate, and these cracks even extend to all the weld structures of the entire bucket lip (flat plate with bucket teeth), causing serious...
