Sheet Metal in the Automotive Industry

Historically, sheet metal has been used extensively to produce automotive body panels. Although sheet metal use has decreased with the advent of fiberglass body panels, sheet metal is still the most popular material for manufacturing automobiles today. The addition of lasers and robotics to the automobile manufacturing process has further expanded the way that sheet metal is processed.

Lasers

Lasers have been used in production facilities since the 1960's. Today, they are used to cut, form holes, engrave, weld or heat treat sheet metal for use in automotive production.

Lasers are used in applications that rely on precise measurements and exact alignments.

The adjustment of lasers is measured in micrometers, or millionths of a meter.

There are many different types of lasers used to alter sheet metal and plastics in the automotive industry.

Carbon dioxide laser- uses a mixture of carbon dioxide, nitrogen and helium to produce a continuous laser output

Continuous-wave laser- this type of laser produces light beams continuously rather than in controlled pulses

Excimer laser-emits light in a UV spectrum that is used for producing high quality edges on parts that are prone to cracking or thermal damage; it falls into the category of pulsed-gas lasers

Gas laser-any laser that uses a gas mixture as the lasing medium; common gases are argon and carbon dioxide

Pulsed laser-emits light in controlled pulses and is preferred for thin materials ; it can be used to create intricate details and work in tight corners without burning

Ruby laser-a solid state laser that uses a synthetic ruby crystal with a chromium impurity as the lasing medium

Solid-state laser-a type of laser that uses a crystal or glass as the host for an impurity to produce the lasing action; especially useful for precise measuring and spot welding

Yttrium aluminum garnet (YAG) laser-ranges in power from a few milliwatts to more than 400 watts; used for cutting, drilling, heat treating and welding operations

Robotics

Robotics are often used for repetitive tasks, monotonous jobs or those parts of the manufacturing process that are physically difficult or take place in environmentally unpleasant conditions. They are directed by computer programs and perform precise operations without human intervention.

Lasers and robotics have significantly increased the speed at which sheet metal can be processed in the automotive manufacturing process. Continued technological advancements in these two areas will further increase the cost effectiveness and productivity of automotive manufacturing facilities.

A Few Easy Ways To Take The Headache Out Of Moving

Moving from one house to another is always a challenge, but it doesn't have to be a nightmare. Here are some simple tips on how to get it done with minimal stress and strain.

• Look at all the alternatives: hiring a moving company, for example, versus renting a truck and doing it yourself. Whichever alternative makes most sense for you, get bids from more than one vendor.
• A few days before the moving company is scheduled to arrive or you're supposed to pick up your rental truck, call to confirm that everything is on track to happen when it's supposed to.
• Prepare your change of address cards in advance and send them out as soon as it's appropriate to do so. The post office, utilities, companies and people you do business with, city hall, friends, relatives – all should be notified of your move.
• Get an early start on packing by concentrating on seldom-used items first. Each box should have its contents and the room those contents belong in written on it clearly.
• Take a hard look at things you seldom or never use and throw away as many of them as you can. The more you throw away, the less you'll have to move. Every item you throw away is one less item to clutter up you new home.
• Use your extra towels and linens to protect breakables. When your supply of these things is exhausted, crumpled newspaper makes an excellent substitute. Write "Fragile" on all appropriate boxes.
• Put your valuables (such as jewelry) and important documents (birth certificates, car titles, etc.) aside in some safe place where they won't be misplaced.
• When the house is empty, go back for a thorough final inspection. Check closets, crawl spaces, basement, attic, out-of-the-way nooks and crannies of all kinds. Have a second person make the same inspection separately.
• Clean your new home thoroughly before moving in. It's infinitely easier that way.
• Decide in advance where you want the heavy furniture. Changing your mind after the movers have departed is no fun – especially for your back!
• Locate all fuses, circuit breakers, and water/gas and electrical valves. Record the meter readings and check the smoke detectors.
• List the phone numbers of the local police and fire stations, doctors, nearby hospitals, etc. Put a copy of your list near each phone.

Above all, plan, plan, plan and plan some more. Make a schedule you can live with, and then stick to it. Preparation and forethought will help you to keep everything under control and finish the move with your sanity and your nervous system intact.
