Abstract
The invention discloses the welding method of loading shovel, it is characterised in that comprise the following steps, 1, weld must be cleaned out before weldering, the weldering meat at original cracking position is taken away, with handing over phase polishing machine mill or carbon arc air gouging, clean ferrum oxide of must polishing after the plane of cracking position；2, to preheat before welding, preheat 98 100 degree in welding position, then weld with welding rod, weldering is the most just stopped, and taps weld seam and weld edge with hammer, taps with hammer after being soldered completely, until weld seam cools down；3, loader bucket body welds with bucket tooth and must assure that through welding, if position while welding gap adds greatly backboard inside bucket tooth.
Description
Technical field
The invention belongs to technical field of engineering machinery, particularly relate to the welding method of loading shovel.
Background technology
The bucket body material of loader is Q345, and its weldability is good.Bucket tooth material is ZGMn13(potassium steel), at high temperature
In single phase austenite tissue, there is good toughness, under impact loading, because of surface layer processing hardening, there is high abrasion
Property.But this steel weldability is poor: one is to cause material embrittlement at welding heat affected zone carbide precipitate；Two is that weld seam produces heat
Crackle, particularly produces liquation crack in Jin Feng district.
Summary of the invention
Technical problem solved by the invention is to provide the welding method of a kind of loading shovel, has reparation bucket tooth efficiency
Height, low cost, effective feature.
In order to solve the technical problem of above-mentioned existence, the technical solution used in the present invention is as follows:
The welding method of loading shovel, comprises the following steps, 1, weldering before weld must be cleaned out, original cracking unit
The weldering meat of position is taken away, with handing over phase polishing machine mill or carbon arc air gouging, and clean ferrum oxide of must polishing after the plane of cracking position；2, before welding
Preheating, preheat 98-100 degree in welding position, then weld with welding rod, weldering is the most just stopped, and taps weld seam with hammer
And weld edge, tap with hammer after being soldered completely, until weld seam cools down；3, loader bucket body welds with bucket tooth and must assure that
Through welding, if position while welding gap adds greatly backboard inside bucket tooth.
Further, second step, selecting model during welding is diameter 3.2J507 welding rod welding material.
Further, the 3rd step, often it is soldered one cracking position lens examination cracks, then uses carbon arc if any crackle
Gouge welds after eliminating again.
Compared with prior art, the invention has the beneficial effects as follows:
After loader bucket body and bucket tooth REPAIR WELDING, weld seam position is the best.The method repairs bucket tooth efficiency height, low cost, effect
The best, there is certain practical value.
Detailed description of the invention
The most peering the preferred embodiments of the present invention illustrate, it will be appreciated that preferred embodiment described herein is only
For instruction and explanation of the present invention, it is not intended to limit the present invention.
The welding method of loading shovel, comprises the following steps, 1, weldering before weld must be cleaned out, originally opening
The weldering meat splitting position is taken away, with handing over phase polishing machine mill or carbon arc air gouging, and clean ferrum oxide of must polishing after the plane of cracking position；2, weldering
To preheat before connecing, preheat 100 degree in welding position, then weld with welding rod, weldering is the most just stopped, and taps weld seam with hammer
And weld edge, tap with hammer after being soldered completely, until weld seam cools down；Cooling purpose is release welding stress, because weldering
After can not do heat treatment.In second step, selecting model during welding is diameter 3.2J507 welding rod welding material.3, loader bucket
Body welds with bucket tooth and must assure that through welding, if position while welding gap adds greatly backboard inside bucket tooth.3rd step, is often soldered together
Cracking position lens examination cracks, welds after then eliminating with carbon arc air gouging if any crackle again.
Claims (3)
1. the welding method of loading shovel, it is characterised in that comprise the following steps, 1, must be by dry for weld cleaning before weldering

Ferrum oxide；2, to preheat before welding, preheat 98-100 degree in welding position, then weld with welding rod, weldering is the most just stopped,
Tap weld seam and weld edge with hammer, tap with hammer after being soldered completely, until weld seam cools down；3, loader bucket body and bucket
Tooth welding must assure that through welding, if position while welding gap adds greatly backboard inside bucket tooth.
2. the welding method of loading shovel as claimed in claim 1, it is characterised in that: second step, select model during welding
For diameter 3.2J507 welding rod welding material.
3. the welding method of loading shovel as claimed in claim 1, it is characterised in that: the 3rd step, often it is soldered one cracking
Position lens examination cracks, welds after then eliminating with carbon arc air gouging if any crackle again.
