Q:Aluminum seamless aluminium oxidation welding line how to do?
That is not possible without welding line, welding line itself is seamed with the largest seamless two kinds of pipe difference! I suggest you confirm, you see the line, if indeed the welding line, or whether the processing or other processes may be bad
Q:Eddy current demonstrator's working principle: why does the magnet fall at different speeds in different aluminum tubes, while the aluminum tubes are the same?
[principle] the experiment instrument used to demonstrate the law of electromagnetic induction, when the magnet falls from the aluminum tube, the aluminum tube in the induction current, this current will hinder the whereabouts of the magnetic flux generated, so the longer the whereabouts of the magnet.
Q:Is the tube of LED lamp all plastic tube well or half plastic half aluminium tube?
Of course, the power is placed inside the aluminum tube, so that the amount of LED heating plus the heating capacity of the power supply is considerable, because the power of this lamp is usually around 20W. If the power is bigger, half of the aluminum tube can not solve its heat dissipation problem. It also proposed another aluminum tube cooling fan: shaped tubes. The fan shaped aluminum frame with heat dissipation structure shape, greatly increasing the radiator area. It puts the power outside the tube so that the half of the aluminum shell is completely made into a radiator. Relative to the semicircular aluminum tube, its heat dissipation area has increased by more than 3 times. Coupled with the power does not put in the tube, but also to reduce heat, which greatly extended the life of LED.

Q:Water heater tube welding seam how
Three, if the defect site is relatively small, can use similar soldering like M51 with M51-F welding wire welding flux, welding the aluminum tube is only suitable for a small trachoma or very small crack, if the crack is much more difficult to weld.
Q:How to solve the aluminum tube cutting,
Aluminum tubes have professional aluminum cutting pieces, and the speed is also related
Q:How to weld aluminium pipe
3, WE53 low temperature aluminum strip for Aluminum Alloy 7 series of welding, welding temperature in 380-400 degrees, the advantage of welding does not need any auxiliary welding flux, thus preventing some residual flux in the process of welding, and the welding strength is very high, can solve the 3 line Aluminum Alloy and castings. Die casting or welding.
Q:Please enlighten master formula of tube weight?
Aluminium tube weight (kg) =0.00879 * wall thickness * (outside diameter wall thickness) * length (M), remaining mm
Q:How can the aluminum pipe burr be convenient?Burr left by drilling
The internal tube is burr! Not very long words can be a round drill clamp in the round head through a 1 mm wide and about 30 mm in the hole, and then put the paper cut up into 30 broad band card in the slot to rotate in the opposite direction wrapped up! Until Guan Zikong was slightly more than a little good! So you can clear burrs on the inner wall of the!
Q:Does the Haier freezer BC/BD-102HT use a brass tube or an aluminum tube or an iron tube?
BC/BD-102HT uses galvanized iron pipes. Of course, copper tube is the best, but the cost is too high, the freezer will be expensive, if there is a freezer that they use a copper tube, but very cheap, such a freezer is not a fake copper tube, it is very thin copper tube, refrigeration is very poor. The aluminium pipe and the iron pipe refrigeration effect are similar, but the aluminum tube quality is soft, the chemical property is lively, is easy to corrode, the service life is bad, galvanized iron pipe many. Galvanized iron pipe is the best choice for both cooling effect and service life, and the cost is not lower than that of aluminum tube.
