Aluminum welding standards
Aluminum welding method: almost all kinds of welding methods can be used for welding aluminum and aluminum, but aluminum and aluminum alloy welding method of the adaptability of various different kinds of welding method has its own applications. Gas welding and arc welding methods, equipment is simple, easy to operate. Welding can be used for less demanding on the welding quality of the welding of aluminum sheet and casting. SMAW welding for aluminum alloy castings. Inert gas welding (TIG or MIG) is the most widely used method for welding aluminum and aluminum alloys. Aluminum and aluminum alloy sheet can be tungsten or tungsten AC TIG pulse welding. Aluminum and aluminum alloy plate can be tungsten arc welding of helium, argon-helium mixed gas tungsten arc welding, MIG welding, pulsed MIG welding. MIG welding, pulsed MIG welding is widely applied (argon or argon / helium mixture) for 1 before welding, cleaning before welding: aluminum and aluminum welding, welding should be strictly removed before welding jobs port and wire surface oxide film and oil; 1) Chemical Cleaning Chemical cleaning, high efficiency, stable quality, and size for little clean-up wire, batch production of parts. Soak and scrub the law can be used both methods. Used acetone, gasoline, kerosene and other organic solvents to the oil surface, with 40 ℃ ~ 70 ℃ in 5% ~ 10% NaOH solution Caustic 3 min ~ 7 min (aluminum take longer but not more than 20 min), mobile water rinse and then at room temperature to 60 ℃, 30% HNO3 acid solution 1 min ~ 3 min, mobile wash, dry or cold dry. 2) Mechanical cleaning: large size in the piece, the production cycle is longer, multi-layer welding or chemical cleaning and then stained, usually with mechanical cleaning. First with acetone, gasoline, etc. Wipe the surface with degreasing solvent, and then directly with a diameter of 0.15 mm ~ 0.2 mm of copper wire brush or stainless steel wire brush, brush the exposed metallic luster so far. Generally should not use ordinary sanding wheel or so left on the metal surface sand, welding slag into the molten pool generated defects. There is also available scraper, file and other clean surface to be welded. If stored too long after the clean-up (if more than 24 h) should be reprocessed. 2, plate: aluminum alloy at high temperature, low strength, good flow properties of liquid aluminum in the weld metal welding prone to staying phenomenon. In order to ensure penetration but not collapse, welding often in and around the plate to lift up the metal bath. Plate can be graphite plate, stainless steel, carbon steel, copper or brass rod and so on. Plate to open a circular-shaped surface groove, in order to ensure the weld negative shape. May not add side welding plate forming, but requiring a skilled operator or take strict energy of arc welding automatic feedback control and other advanced technology measures. 3, preheat: thin, small pieces of aluminum generally do not warm up, the thickness of 10 mm ~ 15 mm preheating before welding can be carried out, according to the different types of alloy preheating temperature for 100 ℃ ~ 200 ℃, the oxygen available an acetylene flame, furnace or other heating blowtorch. Preheating can reduce the deformation of the weldment, reducing porosity and other defects. Treatment after welding (1) clean up after welding and after welding to stay in the vicinity of the weld and weld slag and other residual flux will destroy the passive film on aluminum surfaces, and sometimes corrosion of aluminum parts should be cleaned up. Simple shapes, requiring general or workpiece can be washed with hot water, steam blowing easy way to clean brushes, etc.. Demanding and complex shape of the aluminum parts, using a stiff brush in hot water after brushing, and then at about 60 ℃ ~ 80 ℃, the concentration of 2% to 3% of the chromic acid or potassium dichromate solution in the immersion solution 5 min ~ 10 min, and scrubbing with a stiff brush, then wash in hot water washing, drying oven, or hot air drying can also be dry. (2) post weld heat treatment of aluminum containers generally do not require post-weld heat treatment

To do cooking with aluminum pots hazardous it?

Cook with aluminum cooking pot you would hazardous to your health? / If so, what are it? … Some people are accustomed to cooking with aluminum pots that thin aluminum pan, heat transfer is good, not only save fuel and save time. However, according to research confirmed that the long-term use of aluminum cookware allows for excessive intake of aluminum, is not healthy, can also lead to age-related increase in the incidence of dementia …

Aluminum and stainless steel contrast, the stencil used in smoke good? ?
Fume purification rate (ie, degree of fat reduction) depends on the structure and the separation plate material. Soot on the market today generally use separate sheet of stainless steel, aluminum and other materials, stainless steel, the material texture, a grade, but the separation made of stainless steel plate can not compare to the fume purification of aluminum materials. There are two characteristics of aluminum alloy First, good heat dissipation. We all know that smoke is a gas, the fumes of oil separation process is the liquefaction process, the gas can be liquefied when cooled. Aluminum has a good cooling effect, a lot of cooling materials are aluminum, heat sink, such as computer motherboards, power amplifier heat sink; Second, the aluminum alloy surface tension strong separation plate to hit the oil molecules condense into water droplets flow away, the less attached to the wall plate to reduce the pollution of the separation plate. However, the hardness of aluminum alloy material is not stainless steel, single easy variations. As a result, the world Odyssey smoke hood will be a small whirlwind series of single-chip “thick” and use of aluminum materials, which would only increase the hardness and to enhance aesthetics. Will also profile designed as a “Double Eagle” structure, extended exposure to fumes from the heat and siding area, so that a higher degree of oil separation. Because this material is also relatively high construction cost, the use of this material hood not more. Help me
