Welding method

Various types of welding methods For each type of welding method, aluminum and aluminum alloys, but for each type of welding method, there is no difference in the suitability, and each type of welding method is available. Gas-fired Japanese-style electric arc-fired method, equipment and operation method. Welding is possible, and the amount of contact quality is not high. Fired-striped electric arc-fired applicable aluminum alloy. Noble gas welding (TIG or MIG) method The most suitable method for welding aluminum and aluminum alloys.alloy thin plate sizing for TIG polar AC arc welding or TIG polar welding. lloy thick plate slabs for argon welding, helium mixed stakes, helium welding, helium welding, helium welding, helium welding, helium welding. Fused polar body helium, Fused polar gas body helium for application Koshirai Yue

Pre-burning equipment

1. Kiyori Mae: At the time of welding of aluminum alloys,  Mae application 

1) Chemical cleansing Chemical cleansing efficiency is high, quality is determined, suitable for Qing dynasty, and the size is not large. Possible soaking method Japanese rubbing method Two types. Available kerosene, steam oil, soot oil, etc. Acetone solvent surface degreased, for 40 ℃ -70 ℃ 5% -10% NaOH solution washing 3 min-7 min ， For adhesion Room temperature up to 60 ℃ 30% HNO3 solution Pickling 1 min ~ 3 min ， Flowing fresh water wash ， Soluble or low temperature drying.

2) Machine clarification: In-process size comparison, production cycle comparison, multi-layered flame or chemical cleaning, and then eradication. Preliminary use of gasoline, steam oil, etc., oil removal from the surface of the solvent, and subsequent direct use of 0.15 mm to 0.2 mm diameter. General sandpaper or ordinary sandpaper, sandpaper-free metal surface, welded metal surface at the time of welding, welding residue, etc. The surface of the file, such as a file, a spatula, etc.

After the Qing dynasty, the time has passed for a long time.

2. Aluminum alloy: Low temperature at high temperature, good fluid flow performance, easy production of aluminum metal at the time of contact with aluminum.a cave-in plate for welding at the time of welding. Graphite board for shaving board, non-stainless steel board, copper board, copper board or sword stick, etc. The surface of the sword plate is open, and the arc-shaped tank is molded on the other side. It is possible to use a single-sided, double-sided molding, but the required welding operation is mature or the energy is applied to the electric arc, and the ability to control the automatic feedback, etc.

3, Flame front heat: Thin, small aluminum general useless heat, thickness 10 mm to 15 mm, advancing flame front heat, rooting non-type type aluminum alloy heat temperature possible 100 ° C to 200 ° C, available oxide Ichioto Flame, heating of electric furnace or blow torch, etc.Heat usable  Small transformation, Small gas hole, etc.
