The application of aluminum alloy is becoming more and more widespread with the development of the industry. Many factors are promoting the application of aluminum alloys, such as environmental protection, reduction of greenhouse gas emissions, development of light weight, etc. When we need to deal with aluminum alloy, it is necessary to know and […]

Find the problem-aluminum and alu alloy Aluminum and alu alloy have  characteristics of low melting point, good thermal conductivity, easy oxidation, low temperature strength, and substantially no discoloration of solid-liquid transition, which brings a certain degree of difficulty to welding. The biggest problem is that the surface of the aluminum alloy weldment has dense aluminum […]

  Filler metals As we our know that approximately 80 percent of the aluminum filler wire sold worldwide is either 4043 or 5356. So, most often one or the other will be appropriate for your application. Yes, you are correct in saying that 5356 is stronger. But your distributor is also correct in suggesting you […]

There are various methods for classifying flux-cored wire. Such as classification according to the manufacturing method of flux-cored wire. Classification of shielding gas when welding of flux-cored wire. Classification by the use of flux-cored wire.Classification of welding powder composition of flux-cored wire. Today, we will introduce you to the flux-cored wire under various classification methods: […]

The selection of welding wire diameter depends on the thickness of the welding piece, position of the welding seam, welding level and form of welding joint. In general, the diameter of the welding wire is selected according to the thickness of the welding part.Thick welding parts, should choose a larger diameter of the welding wire. […]

The welding wire is one of the indispensable tools for welding operations. How much do you know about the welding process? With the continuous advancement of the times, the welding process is constantly developing and updating. Of course, the welding wire is also progressing with the continuous improvement of the welding process. Since the welding […]

Instructions Make sure the consumbale has adapted the environment tempreture before unpacking the package. Remove dirts such as oil and dust from the groove before welding. The quality of the weld joint will be better if the humidity of the welding room is contrled. you’d better take the quantity everyday required before entering the construction […]

welding rod 1. Notes (1) Electrode storage Note that the warehouse should be ventilated and dry, and the relative humidity of the air should be controlled below 60%. Keep the distance between the ground and the wall at a distance of 30cm. (2) Separate the model and specifications and store them. (3) During the handling […]

A process known to join a workpiece by heating or pressurizing, or a combination of both, and with or without a filler material, is referred to as welding. The workpiece can be made of various metal materials of the same kind or different types, such as metal, non-metal materials (plastic, graphite, ceramic, glass, etc.), or […]

Base metal preparation: In order to weld aluminum, the welder must carefully clean the base metal, and use oil or solvent to remove any oxides and hydrocarbons from the aluminum surface. The surface of the aluminum has an oxide ablation temperature of 3,700 degrees Fahrenheit, while the underlying aluminum base material ablate at 1200 degrees […]
