Determine the assembly gap spacing and positioning welding welding process, the thermal expansion of aluminum alloy, resulting in reduction of the weld groove gap Shandong aluminum rods, welded before assembly if left too little space, the welding process will cause two plates groove overlapping, after increasing the weld plate surface roughness and the deformation; on the contrary, the assembly gap is too large manufacturer specializing in the production of aluminum rods, welding is difficult, and there is the possibility of burn right tacking spacing required to ensure tacking. gap, therefore, choose the right tack welding assembly space and distance, is an effective measure to reduce the deformation based on experience, different thickness of the seams reasonable assembly process parameters a, spraying: Color paint aluminum alloy surface coating After drying spray aluminum alloy made good color distribution, the film is firmly applied on a large decorative plant two, roll:... aluminum alloy surface degreasing and chemical treatment, roll quality paint, dry cured from aluminum alloy surface flatness roll film of aluminum rod factory in Jinan, the color sub-pearl and matte, high degree of color simulation;. roll aluminum alloy surface uniform, smooth, seamless coating, shrink Obviously defect holes, scratches, shedding but the surface bubbles, pits, inclusions and other trace defects, which is normal three, Film: Symphony selection of high film or films, after the board is coated specialty adhesives composite coating made of aluminum alloy shiny bright, waterproof, fireproof, with excellent durability and dirt capacity, superior UV performance four: brushed metal: This is a new surface treatment process, which is based alloys aluminum as the base material, the use of imported cloth round diamond surface pull profiling, through a variety of chemical-pressure, roller and other treatment from surface color and bright, uniform, strong fashion sense, gives a strong visual impact. aluminum rods _ Jinan Alcoa aluminum rod manufacturers _ cis (certified merchants) provided by the Aluminum Co., Ltd.
