How To Weld Aluminum?Almost all welding methods can be used to weld aluminum and aluminum alloys, but aluminum and aluminum alloys have different adaptability to various welding methods, and each welding method has its own application. Gas welding and electrode arc welding methods are simple in equipment and easy to operate. Gas welding can be used for repair welding of aluminum sheets and castings that do not require high welding quality. Electrode arc welding can be used for repair welding of aluminum alloy castings. The inert gas shielded welding (TIG or MIG) method is the most widely used method for welding aluminum and aluminum alloys. Aluminum and aluminum alloy sheets Read more

It is understood that aluminum profiles are very common in today’s building materials market. As raw materials for building materials, they can not only produce a large number of commodities, but also have a great demand for construction projects. So, what kind of products can this material be made into? Aluminum profile manufacturers gave us the following answers. Workers from related manufacturers said that aluminum profiles are a kind of material with strong appearance and excellent seismic performance. of. Therefore, aluminum profiles are the raw materials for many products in the market, and they will have a larger development market. The application range of industrial aluminum profiles is getting wider Read more

How important is the role of aluminum extrusion die for aluminum products? It can be said that it plays a vital role in the extrusion process of aluminum profiles and directly affects the quality of aluminum profiles!Then follow us to learn about some problems that we may cause during the die extrusion process in the production of aluminum. The First Is The Problem Of Seam Angle Or Poor Welding There are only two reasons for this problem, the first is that the orifice is small, the metal flow in the welding cavity is not enough to make the metal without sufficient hydrostatic pressure in the welding chamber, the product does Read more

Shortening At the tail end of some extruded products, after low magnification inspection, there is a horn-like phenomenon in the middle part of the cross section, which is called shrinking tail. Generally, the tail of the forward extrusion product is longer than that of the reverse extrusion, and the soft alloy is longer than the hard alloy. The shrinkage of the forward extruded product is mostly in the form of an annular disjoint layer, and the shrinkage of the reverse extruded product is mostly in the shape of a central funnel. The metal is extruded to the back end, and the ingot skin and foreign inclusions accumulated on the dead Read more

The quenched aluminum workpiece is reheated to an appropriate temperature lower than the lower critical temperature Ac1 (the starting temperature of pearlite to austenite transformation during heating), and the metal heat treatment is cooled in air or water, oil and other media after holding for a period of time craft. Or heat the quenched aluminum alloy workpiece to an appropriate temperature, hold it for a period of time, and then cool it slowly or rapidly. Generally used to reduce or eliminate internal stress in quenched steel, or reduce its hardness and strength to improve its ductility or toughness. The quenched aluminum workpiece should be tempered in time, and the required Read more
