成功源于选择

The Power of Choice Shifting the Limits超越极限

Günter Fronius 于 1945 年在奥地利的 Pettenbach 开始将其演绎成一个持续至今的成功故事。截至 2011 年，737 项有效专利证明了我们的创造力。但我们并未停歇：我们在全球的 3,000 多名员工有着同样的目标：成为技术和质量领先企业。因为我们的目标和动机从未改变：我们超越极限。别人发展一小步，我们跨越一大步。

FRONIUS伏能士

通快集团现今是在技术制造方面领先的国际公司。通快创新技术在机床制造方面处于领先地位，如钣金加工和材料加工、激光技术、电子和医疗技术。通快的众多产品为用户带来令人兴奋的、提高生产率的新方法，成为行业新的技术标准。从 1923年以来客户始终信赖我们高品质的技术解决方案。1986 年第一台五轴机床的诞生，20 世纪 90 年代激光和机器人技术的融合皆成为激光加工行业的里程碑。

The TRUMPF group is among the leading international companies in manufacturing technology today. TRUMPF innovations are leading the way in the construction of machine tools for sheet metal and material processing, laser technology, electronics, and medical technology. TRUMPF products set new technical standards, while providing users with exciting new ways of increasing productivity. Since 1923,our customers have relied on us for superior-quality technical solutions. The first five-axis machine in 1986 and the combination of laser and robot technology in the 1990s were milestones in laser processing.

As a technological leader in the area of lasers and laser systems worldwide, TRUMPF Laser GmbH + Co.KG began developing solid-state lasers as early as 1971. In 1985, TRUMPF presented its first CO2 laser with a power of 1KW. Today lasers are developed into a sophisticated tool. The product port fo l io of the Laser Technology d iv i s ion encompasses laser cutting and welding systems for 2D and 3D parts, systems for lasers deposition welding, high-power CO2 lasers, pulsed and cw solid-state lasers, micro-processing lasers as well as marking lasers and systems.

What Günter Fronius started in 1945 on Pettenbach, Austria has now become a modern day success story. 737 Active patents are testimony to our inventiveness as of 2011. Not that we ‘re resting on our laurels. Today, the company has more than 3,000 employees worldwide. Since the very beginning, our goal has not changed: to be the technology and quality leader. We shift the limits of what ‘s possible. While others progress step by step, we innovate in leaps and bounds.

自1950年，我们一直致力于研发电弧焊和电阻点焊解决方案。例如冷金属过渡工艺CMT。这一革命性的焊接技术实现了焊接领域的突破：钢和铝可以焊接在一起。日复一日，我们坚定信念：“破译电弧的DNA”。毫无疑问，我们是全球焊接领域的技术领先者和全球市场的领跑者。

FRONIUS welding technology伏能士焊接技术

Ever s ince 1950, we’ ve been developing innovative comprehensive solutions for arc welding and resistance spot-welding. Like our Cold Metal Transfer technology CMT. This revolutionary welding process has swept away one old prejudice: that you can’ t weld aluminium and steel to one another. Day-in, day-out, we’ re working on our vision: to ‘decode the DNA of the arc’ . No wonder that we’ re the welding-sector’ s technological leader worldwide, as well as being the European market leader.

作为激光和系统制造领域的领导企业，通快早在1971年就开发了固体激光器，1985年通快推出第一台一千瓦的二氧化碳激光器。今天激光器已经发展成一种先进的精密工具。激光技术部门的产品组合涵盖二维和三维部件的激光切割和焊接系统、激光熔敷焊接系统、高功率二氧化碳激光器、脉冲和cw固体激光器、微加工激光器以及激光打标器和系统。

激光焊接 气体保护焊

GMAW

This means that when a new component is being developed, for instance, the relevant high-performance process can also be taken into consideration right from a very early stage. Working together right from the outset is an excellent way of pooling and synergising both partners’ knowledge, and makes for superlative results.

High-performance welding is possible for many very diverse applications. Each of these processes can be used just as effectively for light-gauge sheets as for plates, and for steel as for chrome-nickel or aluminium.

高性能焊接技术应用越来越广泛，这些工艺非常有效的应用在了碳钢、不锈钢、铝合金的薄板、厚板的焊接。

例如，这意味着当研发出一种新型部件时，从最初阶段就可采用相关的高性能焊接工艺。持续的技术合作也是汇集和协调各合作方经验的有效方法，并可到达极佳的焊接效果。

激光深熔焊 气体保护焊 – 高性能焊接

GMAW - High-performance weldingLaser deep penetration welding

当激光束的功率密度超过临界值时(≈ 106 W/cm2)，材料会急剧加热，不仅在表面熔化，而且会产生汽化。

If the power density of the laser beam exceeds the critical threshold (≈106 W/cm2), the material will heat up so intensely that it not only melts at the surface but also vaporizes.

When the laser welding head moves relative to the work piece, the keyhole moves with it under the focused laser beam. Behind the laser beam, the melted materials mix with one another. Once melted and mixed, the material begins to cool, and the weld solidifies into a narrow seam.

The formation of the keyhole is a phenomenon that is associated with deep welding. A much greater seam depth can be achieved using this method than with heat conduction welding . In addition, the high laser output produced during welding enables an absorption level of up to 90%.

The vaporization of the material and the pressure of the dissipating metal vapor causes a vapor channel, or “keyhole”, to be formed in the work piece. Depending on the laser power, the keyhole can extend several millimeters into the material.

材料的汽化和金属蒸汽扩散的压力会导致在工件形成气体通道即“深孔”。根据激光功率的不同，深孔可深入材料迅速延深数毫米。

当焊接头相对于工件移动时，深孔在聚焦光束下也随之移动。 在激光束的后面，熔化的材料互相熔合后，逐渐冷却，焊缝凝结成一条窄缝。

深孔的形成是实现深熔焊的原因。采用这种方法可获得比热传导焊接 更大的焊缝深度。此外，焊接过程中产生的高激光输出可以使材料吸收率高达 90%。
