Abstract
The invention discloses a laser welding method for a titanium alloy blade. The laser welding method for the titanium alloy blade comprises the following steps: processing a groove in a joint, wherein the groove is a Y-shaped groove; and respectively processing T-shaped interlocking components on inclined surfaces of two sides of the groove. Each T-shaped component comprises a first end and a second end, a position where each first end is connected with the corresponding second end is in fillet transition, the T-shaped components are alternately distributed on the surfaces of two sides of the groove, the distance between each two T-shaped components is 4-8 mm, an interlocking structure is formed during welding, a mechanical interlocking structure can be formed between a blind hole filled with welding flux and a base material during welding, therefore, the strength of a welding position is improved remarkably, repeated design experiments of the groove are avoided, and the time is saved.
Description
Technical field
The invention belongs to materials processing technology field, more particularly, to a kind of method for laser welding of titanium alloy blade.
Background technology
Titanium is a kind of important structural metal for growing up the 1950's, and titanium alloy is because high, anti-corrosion with intensity
The features such as property is good, thermostability is high and be widely used in every field.Many countries all recognize the weight of titanium alloy material in the world
The property wanted, is researched and developed to which in succession, and is applied.50～sixties of 20th century, mainly develop aviation and send out
The structural titanium alloy of the high-temperature titanium alloy and body of motivation, develops a collection of corrosion resistant Ti alloy the seventies, since the eighties,
Corrosion resistant Ti alloy and high-strength titanium alloy are further developed.Titanium alloy is mainly used in making aircraft engine compressor part,
Secondly it is the structural member of rocket, guided missile and high-speed aircraft, at present in blade of aviation engine, TiAl alloy is little due to proportion,
Intensity is big, and high temperature resistant has been obtained for application, during the blade of current TiAl alloy is produced, is integrally formed using hot investment casting more
Method, but as the position that blade piece body and base connect is thermal center region, during hot investment casting, easily produce contracting
, during follow-up isostatic pressed easily there is surface and subsides, reduce yield rate in hole shrinkage defect.Laser Welding is to focus on
Laser beam bombards a kind of welding method that the heat produced by weldment is welded as the energy, is added by laser emission during welding
Hot weld junction, by controlling the parameters such as width, energy, peak power and the repetition rate of laser pulse, melts solder side.Swash
Flush weld has the characteristics of energy density is high, fusion penetration is big, speed of welding is fast, deformation is little and fit-up gap adapts to strong, especially in application
There is with, in the welding of slab bigger advantage in precise part welding.
The content of the invention
To solve above-mentioned technical problem, the present invention proposes a kind of laser means for being particularly suited for titanium alloy blade, adopts
Used in titanium alloy blade page body and base junction using Laser Welding and by the way of arranging interlocking member, improve blade connection
Intensity, improves welding quality.
The complete technical scheme of the present invention includes：
A kind of laser-arc composite heat power supply cold metal transfer welding method of titanium alloy blade, it is characterised in that include as
Lower step：
