Orbital welding

Written by Mahesh Ugale

Continued from page 1

• Orbital welding may be used in applications where a tube or pipe to be welded cannot be rotated or where rotation ofrepparttar part is not practical.

• Orbital welding may be used in applications where access space restrictions limitrepparttar 102798 physical size ofrepparttar 102799 welding device. Weld heads may be used in rows of boiler tubing where it would be difficult for a manual welder to use a welding torch or viewrepparttar 102800 weld joint.

• Many other reasons exist forrepparttar 102801 use of orbital equipment over manual welding. Examples are applications where inspection ofrepparttar 102802 internal weld is not practical for each weld created. By making a sample weld coupon that passes certification,repparttar 102803 logic holds that ifrepparttar 102804 sample weld is acceptable, that successive welds created by an automatic machine withrepparttar 102805 same input parameters should also be sound.

Industries and Applications for Orbital Welding

Aerospace: As noted earlier,repparttar 102806 aerospace industry wasrepparttar 102807 first industry to recognizerepparttar 102808 requirement for orbital welding. The high-pressure systems of a single plane can have over 1,500 welded joints, all automatically created with orbital equipment.

Boiler Tube: Boiler tube installation and repairs offer a perfect application for orbital welding. Compact orbital weld heads can be clamped in place between rows of heat exchanger tubing where a manual welder would experience severe difficulty making repeatable welds.

Food, Dairy and Beverage Industries: The food, dairy and beverage industries require consistent full penetration welds on all weld joints. Most of these tubing / piping systems have schedules for cleaning and sterilization in place. For maximum piping system efficiencyrepparttar 102809 tubing must be as smooth as possible. Any pit, crevice, crack or incomplete weld joint can form a place forrepparttar 102810 fluid insiderepparttar 102811 tubing to be trapped and form a bacteria harbor.

Nuclear Piping: The nuclear industry with its severe operating environment and associated specifications for a high quality weld has long been an advocate of orbital welding.

Offshore Applications: Sub-sea hydraulic lines use materials whose properties can be altered duringrepparttar 102812 thermal changes that are normal with a weld cycle. Hydraulic joints welded with orbital equipment offer superior corrosion resistance and mechanical properties.

Pharmaceutical Industry: Pharmaceutical process lines and piping systems deliver high quality water to their processes. This requires high quality welds to ensure a source of water fromrepparttar 102813 tubes that is uncontaminated by bacteria, rust or other contaminant. Orbital welding ensures full penetration welds with no overheating occurring that could underminerepparttar 102814 corrosion resistance ofrepparttar 102815 final weld zone.

Semiconductor Industry: The semiconductor industry requires piping systems with extremely smooth internal surface finish in order to prevent contaminant buildup onrepparttar 102816 tubing walls or weld joints. Once large enough, a build up of particulate, moisture or contaminant could release and ruinrepparttar 102817 batch process.

Tube/Pipe Fittings, Valves and Regulators: Hydraulic lines and liquid and gas delivery systems all require tubing with connector fittings. Orbital systems provide a means to ensure high productivity of welding and improved weld quality. Sometimesrepparttar 102818 tubing may be welded in place to a valve or regulator body. Hererepparttar 102819 orbital weld head providesrepparttar 102820 ability to produce high quality welds in applications with restricted access torepparttar 102821 weld joint.

Web Awards- And how to choose

Written by Dan Anderson

Continued from page 1

Past Winners- Review sites that have previously wonrepparttar award you are interested in applying for. If these sites are all of a high standard and quality, pick one and contactrepparttar 102797 webmaster. Inquire onrepparttar 102798 response from his users,repparttar 102799 award service, and anything else you would like to know. Usually you’ll get an informative reply.

Amount of Awards- No one appreciates going to a website an as soon as it loads they are bombarded with about twenty awards in a row. This is just plain bragging and obtrusive torepparttar 102800 users experience. I suggest choosing one or two reputable awards and having them on a separate page or onrepparttar 102801 bottom ofrepparttar 102802 site where all your other information is.

Free Applications Versus Paid- This is affected by your budget, preference, and needs. If you haverepparttar 102803 cash to apply for a paid award site do it. When your paying forrepparttar 102804 service your site will be reviewed more diligently, scored harder, andrepparttar 102805 rating will be more honest and accurate. With a paid application your site will be inrepparttar 102806 running with other quality sites because no ones going to dish out anywhere from ten to a few hundred dollars to have their poorly made site rejected.

In conclusion, there are many award sites to choose from. Choosingrepparttar 102807 right one can boost credibility, traffic, and page rank. Choosing a low quality, hand out, award could loose you customers for life and make your site look unprofessional. Do not rely on awards to make you an instant expert or “the guys to go to”, butrepparttar 102808 right one will show users that your work is appreciated and recognized as a quality site and that will reflect on your products, staff, and content.

I, Dan Anderson, am the owner and operator of the internet store http://www.shopwithdan.com. We sell mesh hats: blank, custom, predesigned. After looking at a few awards sites I came to the above conclusions and I wanted to share them with others.
