  • Publication number: 20180169786
    Abstract: A method for manufacturing metal strip comprises abutting at least two metal strips to form a abutment interface between each other, then welding the metal strips along the abutment interface by a laser light to form a weld pass with a welding penetration depth between the metal strips, and a reflected light is reflected from the weld pass, and finally receiving the reflected light by a spectrometer which can determine the welding penetration depth according to the reflected light spectrum. A welding parameter can be selectively adjusted according to the welding penetration depth to correct the welding penetration depth in real time, and the follow-up weld pass can conform to the specification for decreasing weld defective ratio.

  • Publication number: 20170303746
    Abstract: A baby bathing net frame, applied with a bathing basin, includes a support frame, a carrying net and a buoyant element. The support frame includes an upper rod enclosing into a rectangle, two side rods and a lower rod. The upper rod is hung at an edge of the bathing basin, and the lower rod is in contact with a lower portion of the bathing basin. The carrying net is disposed on the support frame and is for carrying the baby. The buoyant element is disposed on the support frame and away from the upper rod. When bathing water is present in the bathing basin, buoyancy of the buoyant element causes the lower rod to float and depart the lower portion of the bathing basin. Thus, the baby is kept afloat on the bathing water surface through the buoyancy of the buoyant element when taking a bath.
