Hello,I have read a lot of opinionsThe standard seems to be brushing with a stainless steel brush in the same direction a bit (or stainless steel wheel?), cover it in acetone, then spraying it down with water followed by drying it.Is this accurate? Are their superior methods or changes at all?Thank you!
Although there is the chance of it being beach weather in February or March, it's not likely going to happenDoesn't matter when spring break is, it almost always rainsEven in the past several years of droughtIt can be in the 40-50s at night and peaks to the mid to high 60s in the day timeIf you want to come, relax, with gorgeous views comeBut if you are planning on coming to sunny SoCal in the winter and come back with a tan, not very likelyA better option may be Florida (although, think it might be the rainy season there too)Off the top of my head, I can't think of a great hotel that is walking distance to everything and sceneryThe beaches with scenery are typically more remoteLaguna Beach might be a good optionThe Pacific inn in Seal Beach Seal Beach is very charming but not especially scenicShorebreak Hotel in Huntington (Hyatt Hilton too)Also, remember Uber Lyft are cheapYou can get anywhere with them.
If you want to go to the popular Hollywood then you require to produce a visit to Los Angeles and that hotelbye is the area to startIn Hollywood you will see landmarks like the Walk of Fame (stars on the sidewalk), the Hollywood Sign, the Hollywood Bowl and moreLos Angeles can also be a place for all the family because this place is the home to several world-famous amusement parks like Universal Studios, Disneyland and much moreIn Los Angeles you may also got to savor the hot climate and beaches so regardless of one's passions, Los Angeles makes an ideal getaway.
All of these are good practicesCleaning with acetone or other solvents should take place BEFORE any grinding or brushingThe point of this step is to simply to remove dirt and greaseThe point of using a stainless wire brush or wire wheel is to strip off the thin film of aluminum oxide, as well as removing any kind of remaining inorganic contaminantsIf you grind or use sandpaper, a wire brush is still recommended as those methods can leave grit and other contaminants behind The oxide film causes problems with fusion and penetration, as well as contaminating the weld, causing inclusions and making it more brittleSometimes if you try to weld aluminum that hasn't been scrupulously cleaned, the filler will just float on top of the oxide layer and not fuse at allMIG welding aluminum is particularly susceptible to this problemIf you degrease the metal AFTER this step, the bare aluminum will react with the water and/or acetone causing the oxide film to reform immediatelyJoints should be ground and/or brushed Immediately prior to weldingAlso be sure to use a brush or grinder that has only been used on aluminum, to avoid cross-contamination.
