Description
Technical field
The present invention relates to a kind of building stones chain saw laser welding process, belong to welding technology field.
Background technology
In prior art, the inherently individual problem of welding of chain saw blade, due to chain saw blade and supporting body material not
Together, and weldability is poor, it is difficult to carry out fusion welding to it, soldering is typically all used.
Laser welding can be realized that the principle of laser welding can be divided into heat-conduction-type using continuous or pulse laser beam
Welding and Laser Deep Penetration Welding.Power density is less than 104~105 W/cm2For heat conduction welding, now fusion penetration is shallow, speed of welding is slow；
Power density is more than 105~107 W/cm2When, metal surface is recessed into " hole " by heat effect, forms deep penetration welding, with welding speed
The characteristics of degree is fast, depth-to-width ratio is big.
The principle of laser welding is made up of optics oscillator and the medium being placed between the end mirror of oscillator hole two.Medium
When being excited to higher-energy state, start to produce same-phase light wave and the roundtrip between two end mirrors, form the string knot of photoelectricity
Effect, light wave is amplified, and is obtained enough energy and started to launch laser.
The present invention carries out fusion welding using laser to building stones chain saw, not only meets the requirement of its Weld Performance, and significantly carry
High welding efficiency.

A kind of building stones chain saw laser welding process is provided.
According to the technical scheme that provides of the present invention, building stones chain saw laser welding process, step is：
（1）Welding preparation：Use angle grinder cleaning saw head, it is ensured that solder side is smooth, can closely be pasted with chain to be welded
Close；Check whether chain to be welded is qualified, confirm without anti-loaded, burr, the problem of the influence welding effect such as breach；
（2）Preweld cleaning：Solder side is cleared up using acetone or absolute alcohol, it is ensured that oil-free is anhydrous, free from admixture must
When wanting, welding is cleared up or cleaned using fixture；When using alcohol cleaning when, need etc. alcohol thoroughly volatilization after carry out again it is next
Walk work；
（3）Docking：Building stones chain saw to be welded is cleared up into interface, fixture opposite position is positioned over by design method,
Clamping device, is tightened with hand and is advisable, and is confirmed the gap of saw head and chain, if any deviation, is finely adjusted in time, it is ensured that welding result
Well；
（4）Welding：Building stones chain saw is welded, adjusting device state and technological parameter, welding condition is：Power
1300 ~ 1500W, defocusing amount+1.5 ~+2.5mm, 2090 ~ 3050mm/min of speed of welding, 13 ~ 17L/min of shield gas flow rate,
Gas drop point is away from 13 ~ 17mm of molten bath, and gas shield angle is with solder side into 27 ~ 33 °, and laser incident angle is vertical with solder side；
（5）Postwelding is checked：Confirm that weld appearance brilliant white is uniform, no splashing, stomata etc. are bad.
Beneficial effects of the present invention：The present invention improves production efficiency, passed through on the basis of properties of product requirement is met
Laser welding relevant parameter is adjusted, and combines corresponding pressing device and carries out welding processing, weldquality and performance is being ensured
In the case of greatly improve welding efficiency, simplify welding process.
