Aluminum seamless aluminium oxidation welding line how to do?
Tubes are generally divided into seamed tubes and seamless tubes, general is seamed, there is also the welding line, the surface treatment of high demand, there may appear welding line, this is a decision process of aluminum tube itself, can not be 100% to avoid; the other is seamless aluminum, if it is truly seamless
If you decide to buy is seamless aluminium oxide, it is certainly not possible after the welding line, if there is a welding line, that is the hot extrusion of aluminum, aluminum is seamed we usually say, if it is oxidized welding line, there is no way to solve, can't use it can only be scrapped in fact, the hot extruded aluminum tube also can avoid the welding line, this time you have to order and that of the factory, this can be solved above the mold! At least your eye is very ugly after oxidation of a welding line. In fact, seamed pipe and seamless pipe mainly is the surface quality, but the mechanical properties!
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
