China is luggage manufacturing country, China has formed a large luggage manufacturer. International market demand to expand, driven by growth in exports of luggage, so luggage exports continued to show steady growth. As in recent years, the rise of the domestic industry, especially factor ISO industry requirements, the pursuit of product packaging, transportation The integrity of the aluminum box applications also increased. Widely used in public security, fire protection, anti-terrorism, a number of military aviation category, outdoor photography, field surveys, scientific exploration, etc., carefully maintain your valuable equipment. After the damaged military equipment boxes, aluminum welding wire welding usually use 301 and 311 of Al-Si wire to left welding method, welding torch and work into a 60 ° angle, aviation equipment boxes manufacturers, welding thickness 15mm or more to the right welding method , aluminum box Aluminum military equipment boxes, torch and workpiece at 90 ° angle in the air, aluminum oxide combined with simple to produce fine aluminum oxide film (thickness of about 0.1-0.2μm), m.p. high (about 2050 ℃), far beyond the melting point of aluminum and aluminum alloys (about 600 ℃ or so). alumina density 3.95-4,10g / cm3, aluminum is approximately 1.4 times the alumina film look easy absorption of moisture, welding, which prevents fusion of the base metal. It simply constitute pores. slag, equipment boxes, not fusion and other shortcomings, resulting in reduced weld function.
