Looking at the Working Principle Behind Laser Welding
The modern use of laser welding is rooted in the scientific discovery of the first laser in the 1960s, when the effects of an amplified light beam forced by radiation emission were put into practice. The working principle behind laser welding actually lies in the emission generated at the meeting point between light and metal, with the latter emitting force radiation. Presently, laser welding is expanding in various domains of activity since it brings enormous advantages with it such as a very deep weld penetration and minimal levels of heat inputs which cannot be achieved with traditional welding technologies.
The energy transfer is the one that makes the difference between classical welding and laser welding in various domains of activity. We can talk about two elements that characterize the efficiency of laser welding; first of all the heat ratio required by a specific workpiece and then the melting power in the fusion area. Furthermore, laser welding does not depend on AC or DC outputs and it is not limited by the conductive property of a specific material. The contact and fusion are possible with almost any material without even creating x-rays or requiring the formation of a vacuum.
The working principle in laser welding is the energy of light, hence the results are almost impeccable with a welded joint that has highly superior resistant properties. The penetration of a metal piece is directly influenced by its physical properties like conductivity, thickness or density; when a concentrated beam of energy is applied to a workpiece, the melting is immediate before heat may affect the operational area as such. The force of the energy beam in a focal point is given by the careful choice of special lenses. Correct mirror and lens applications in laser welding may guarantee the concentration of the light beam on spots smaller that 0.005.
The main industries to profit from the use of laser welding are aerospace building, military and defense, medical research, instrumentation, electronics and so on. Laser welding actually improved the execution of many delicate works that were almost impossible to achieve before, and here we refer to the creation of very deep or narrow welds and the absence of any distortions in the process. Small or very thin items could not be joint very well before the development of laser welding, not to mention that the resistance of the welds is incredible as compared to those resulted from classical welding procedures.

What's the ugliest bike you've ever ridden?
I once had a '70 Honda CL 450 a guy ran without oil. The engine locked up which then sheared off the studs holding the rear sprocket on. It had set behind his barn for a number of years in the weather, the seat cover was rotten away, rust everywhere, chain locked up, plastic tach and speedo lens hazed over and at some time had a secondhand paint job applied with either a very coarse brush or corn cob. I bashed the pistons out of the block with a sledge hammer and got the engine running, welded up the rear sprocket and tied a car battery onto the luggage rack. It ran well, but in typical 450 fashion, vibrated like a jackhammer.
'81 Kawasaki KZ1300. Originally had a fairing, we took it off. It made the bike even more odd-looking. Those that know it also know it was a 6-cylinder bike that always ran rich. My dad was killed on this bike in '95. I have fond memories of it, but it was indeed ugly.
It always drew attention, though... I remember sitting at a Sonic by my dad, and a gentleman walked up to us, staring at the KZ1300. He asked, "wow, how big is that thing?". My dad, without missing a beat, answered with "oh, about 7 or 8 inches".
I fell off my bike. I was laughing so hard.
My Wisconsin Film Festival 2010 movie: Growing in Knowing
Erika and I became friends when we were 7 years old. We lived on the same highway in the same unincorporated town. We remained pals throughout school, attended the same college for a while, and even stood up in each other's wedding. Now she's known as the Butterfly Jester, and welding is her passion.
