Laser welding machine has become a new industrial technology in the process of industrial welding because of its advantages of fast welding speed, high precision, high efficiency and smooth and beautiful weld. Laser welding machine has been widely used, but many people do not know what materials laser welding machine can weld.

1.模具鋼

1. Die steel

激光焊機可用于各種模具鋼的焊接，焊接效果良好。

Laser welding machine can be used for welding various die steels with good welding effect.

2.碳鋼

2. Carbon steel

鋼是用激光焊接機焊接的，焊接質(zhì)量取決于雜質(zhì)含量。為了獲得良好的焊接質(zhì)量，需要在碳含量超過0.25%時進行預(yù)熱。當不同含碳量的鋼焊接在一起時，焊槍可以稍微傾斜到低碳材料的一側(cè)，以保證接頭的質(zhì)量。由于激光焊機的加熱速度和冷卻速度都很快，所以在焊接碳素鋼時。隨著碳含量的增加，焊接裂紋和缺口的敏性也隨之增加。中、高碳鋼和普通合金鋼可以用激光焊接，但需要預(yù)熱和焊后處理，以解決應(yīng)力，避免裂紋。

Steel is welded by laser welding machine, and the welding quality depends on the impurity content. In order to obtain good welding quality, preheating is required when the carbon content exceeds 0.25%. When steels with different carbon contents are welded together, the welding gun can be slightly tilted to the side of low-carbon material to ensure the quality of the joint. Because the heating speed and cooling speed of laser welding machine are very fast, when welding carbon steel. With the increase of carbon content, the sensitivity of welding crack and notch also increases. Medium and high carbon steel and ordinary alloy steel can be welded by laser, but preheating and post weld treatment are required to solve the stress and avoid cracks.

3.合金鋼

3. Alloy steel

只要選擇合適的焊接參數(shù)，低合金鋼和高強度鋼的激光焊接就能獲得具有母材力學性能的接頭。

As long as appropriate welding parameters are selected, the joints with mechanical properties of base metal can be obtained by laser welding of low alloy steel and high strength steel.

4.不銹鋼

4. Stainless steel

一般來說，不銹鋼焊接比常規(guī)焊接更容易獲得高質(zhì)量的焊接接頭。由于激光焊接的高焊接速度和熱影響區(qū)很小，減輕了過熱和線膨脹系數(shù)對不銹鋼焊接的不利影響，不存在氣孔、夾雜物等缺陷，與碳鋼相比，不銹鋼具有低的導熱性、高的吸收和熔化效率，更容易獲得深熔深焊接。通過低功率激光焊接機廠家，可以獲得外觀良好、焊縫光滑、美觀的接頭。

Generally speaking, stainless steel welding is easier to obtain high-quality welded joints than conventional welding. Due to the high welding speed and small heat affected zone of laser welding, the adverse effects of overheating and linear expansion coefficient on stainless steel welding are reduced, and there are no defects such as pores and inclusions. Compared with carbon steel, stainless steel has low thermal conductivity, high absorption and melting efficiency, and it is easier to obtain deep penetration welding. Through the manufacturer of low-power laser welding machine, the joint with good appearance, smooth weld and beautiful appearance can be obtained.

5.銅和銅合金

5. Copper and copper alloys

銅和銅合金焊接容易引起熔透問題，應(yīng)采用集中大功率熱源和預(yù)熱措施；當工件厚度較薄或結(jié)構(gòu)剛度較小時，沒有防止變形的措施，焊接后容易產(chǎn)生較大變形，但焊接接頭受到較大的剛性約束時，容易產(chǎn)生焊接應(yīng)力；銅和銅合金焊接時也容易出現(xiàn)熱裂紋。氣孔是銅和銅合金焊接中常見的缺陷之一。

The welding of copper and copper alloy is easy to cause penetration problems, so centralized high-power heat source and preheating measures should be adopted; When the thickness of the workpiece is thin or the structural stiffness is small, and there are no measures to prevent deformation, it is easy to produce large deformation after welding, but when the welded joint is subject to large rigid constraints, it is easy to produce welding stress; Copper and copper alloys are also prone to thermal cracks during welding. Porosity is one of the common defects in copper and copper alloy welding.

6.鋁和鋁合金

6. Aluminum and aluminum alloys

鋁和鋁合金是一種高度反射材料。隨著溫度的升高，氫在鋁中的溶解度急劇增加，溶解氫成為焊縫的缺陷源，焊縫中有許多氣孔，但深熔焊根部可能會出現(xiàn)空洞，焊縫成形不良。

Aluminum and aluminum alloys are highly reflective materials. With the increase of temperature, the solubility of hydrogen in aluminum increases sharply. Dissolved hydrogen becomes the defect source of the weld. There are many pores in the weld, but there may be cavities at the root of deep penetration welding and poor weld formation.

激光焊接機材料遠遠超過這些材料。激光焊接廠家可以在各種不同的金屬之間進行。結(jié)果表明，在一定條件下，激光焊接廠家可以在銅-鎳、鎳-鈦、銅-鈦、鈦-鉬、黃銅、低碳鋼-銅和其他不同金屬之間進行。

Laser welding machine materials far exceed these materials. Laser welding can be carried out between different metals by manufacturers. The results show that under certain conditions, laser welding manufacturers can carry out between copper nickel, nickel titanium, copper titanium, titanium molybdenum, brass, low carbon steel copper and other different metals.
