SAW uses electrodes of continuous wire, solid or flux- or metal-cored. Selection depends on base-metal composition and thickness, flux, joint design, and cleanliness. AWS specifications A5. 17 and A5.23 detail filler materials for SAW of carbon and low-alloy steels; A5.9 and A5.1, filler metals weld corrosion-resisting stainless steels and nickel alloys, respectively.Hardfacing ElectrodesHardfacing welds a wear-resistant material to a substrate-base material that is commonly mild, alloy, or stainless steel. Hardfacings can be deposited manually using SMAW electrodes; semiautomaticaly using solid wire and self shielded flux cored electrodes; or automatically by submerged-arc welding. The method chosen depends on the size and accessibility of the area to be surfaced. "Fuel filters on the tractors are removing 90% of these particles, but in Texas there are nearly 3 million in the 2- to 5-micron size compared to about 100,000 in Iowa. Even with only 10% of the particles getting by, there are still plenty of contaminants to cause problems," he says.Clampitt''s study shows that drier conditions in Texas contribute to more dust in storage tanks. However, he says he''s found more problems with the portable tanks used to transfer fuel to the field."Most farmers with injector problems use pickup tanks or tanks mounted on trailers to take fuel to the field. The fuel in these tanks is usually agitated, so contaminants are in suspension. The tanks often don''t have a filter because the operator doesn''t want to slow fueling capacity. They often don''t have a proper vent cap and the fuel nozzle isn''t shielded from road dust," he says. Petroleum storage is the greatest environmental risk on most farms Leave it to my friend Butch, a 2-handicapper who looks at the hole while he putts but is otherwise not annoying at all, to make sense out of it all. "It really comes down to expectations," he says. "Everyone wants the trip to be exactly as they imagined it, as they remember last year''s trip. Of course, that memory is warped--so they''ve got no chance. They set themselves up."Butch''s words reminded me of that old Greek saying, "You can''t step into the same river twice." Add something about allowing generous drops from the bank and that pretty much sums it up. ©2003 www.circular-saws.net All rights reserved. |
