一、激光手持焊是一種利用激光束進(jìn)行焊接的技術(shù)，其工作原理如下：

激光產(chǎn)生

激光手持焊設(shè)備中的激光發(fā)生器通過激勵源（如脈沖氙燈、半導(dǎo)體激光器等）向增益介質(zhì)（如釹玻璃、YAG晶體、光纖等）輸入能量，使增益介質(zhì)中的粒子實(shí)現(xiàn)能級躍遷，形成粒子數(shù)反轉(zhuǎn)分布，從而產(chǎn)生受激輻射，輸出高能量密度、高方向性、單色性好的激光束。

激光傳輸 

產(chǎn)生的激光束通過光纖等傳輸介質(zhì)傳導(dǎo)至手持焊接頭。光纖具有良好的柔韌性和低損耗特性，可將激光高效地傳輸?shù)胶附硬课?，同時方便操作人員靈活移動手持焊接頭進(jìn)行焊接作業(yè)。

激光聚焦與作用。

在手持焊接頭中，激光束通過聚焦透鏡等光學(xué)元件進(jìn)行聚焦，使激光束在焊件表面形成一個極小的光斑，從而提高激光的能量密度。當(dāng)聚焦后的激光束照射到焊件表面時，激光的能量被焊件材料吸收，使焊件表面迅速熔化甚至汽化，形成一個匙孔。隨著激光束沿著焊接方向移動，匙孔也隨之移動，周圍的液態(tài)金屬會不斷填充匙孔后方的空間，冷卻凝固后就形成了焊縫，從而實(shí)現(xiàn)焊接連接。

  I、Handheld laser welding is a welding technology that uses a laser beam, and its working principle is as follows:

 Laser Generation

 In the handheld laser welding equipment, the laser generator inputs energy to the gain medium (such as neodymium glass, YAG crystal, optical fiber, etc.) through an excitation source (such as a pulsed xenon lamp, semiconductor laser, etc.), causing the particles in the gain medium to undergo energy level transitions and form a population inversion distribution. As a result, stimulated radiation is generated, and a laser beam with high energy density, high directivity, and good monochromaticity is output.

Laser Transmission

The generated laser beam is conducted to the handheld welding torch through a transmission medium such as an optical fiber. The optical fiber has good flexibility and low loss characteristics, which can efficiently transmit the laser to the welding position. At the same time, it is convenient for the operator to flexibly move the handheld welding torch for welding operations. 

Laser Focusing and Action

In the handheld welding torch, the laser beam is focused through optical components such as a focusing lens, making the laser beam form a very small spot on the surface of the welded part, thereby increasing the energy density of the laser. When the focused laser beam irradiates the surface of the welded part, the energy of the laser is absorbed by the material of the welded part, causing the surface of the welded part to melt rapidly or even vaporize, forming a keyhole. As the laser beam moves along the welding direction, the keyhole also moves accordingly. The surrounding liquid metal will continuously fill the space behind the keyhole. After cooling and solidification, a weld seam is formed, thus achieving the welding connection.

二、HTHJ--系列手持激光手持焊機(jī)機(jī)器的用途

         手持激光焊機(jī)廣泛應(yīng)用于鈑金加工、軌道交通、汽車、工程機(jī)械、農(nóng)林機(jī)械、電氣制造、電梯制造、家用電器、糧食機(jī)械、紡織機(jī)械、工具加工、石油機(jī)械、食品機(jī)械、廚具衛(wèi)浴、裝飾廣告、激光對外加工服務(wù)。

       手持激光焊機(jī)操作簡單，無需專業(yè)焊接技術(shù)經(jīng)驗(yàn)，簡單培訓(xùn)2小時即可開始操作。焊接速度超快。一臺手持式激光焊機(jī)基本可以替代3-5臺普通焊機(jī)的輸出。手持激光焊機(jī)焊接基本上可以不用耗材，節(jié)約生產(chǎn)成本。焊接之后，焊縫光亮、白皙，基本無需打磨即可。具有能量集中、熱反射范圍小、產(chǎn)品不易變形等優(yōu)點(diǎn)。激光焊機(jī)能量集中，焊接強(qiáng)度很高。

II. Applications of the HTHJ-series Handheld Laser Welding Machine

Handheld laser welding machines are widely used in various fields, including sheet metal processing, rail transit, automotive manufacturing, construction machinery, agricultural and forestry machinery, electrical manufacturing, elevator manufacturing, household appliances, grain machinery, textile machinery, tool processing, petroleum machinery, food machinery, kitchenware and bathroom products, decoration and advertising industries, as well as laser outsourcing processing services.

The handheld laser welding machine is easy to operate. Without the need for professional welding technical experience, operators can start working after just 2 hours of simple training. It features an extremely fast welding speed. Basically, one handheld laser welding machine can replace the output of 3 to 5 ordinary welding machines. Handheld laser welding machines generally require almost no consumables, which helps to save production costs. After welding, the weld seam is bright and white, and basically does not need to be polished. It has the advantages of concentrated energy, a small heat reflection range, and the property that the products are not easily deformed. The energy of the laser welding machine is concentrated, resulting in a very high welding strength.
