What is the reason for the sticky electrode during welding
Electrode sticking is the phenomenon of electrode and part sticking together when the welder spot welds and the electrode and parts form an abnormal weld. In severe cases, the electrode is pulled out and the cooling water flow causes the parts to rust. There are four main reasons for electrode st...Read more -
When welding aluminum tubes, the surface always turns black. What should I do
Porosity is very common in aluminum welding. There are a certain amount of pores in the base material and in the welding wire, so it is necessary to avoid large pores during welding to ensure that the pores do not exceed the standard. When the humidity exceeds 80℅, welding must be stopped. The pr...Read more -
Narrow gap welding process should not use a single concave weld, so what should be used
The narrow gap welding process belongs to the deep and narrow groove welding process of thick workpieces. Generally, the depth-to-width ratio of the groove can reach 10-15. When the submerged arc welding process is used, there is a problem of slag removal and removal of the slag shell of each we...Read more -
Welding of titanium
1. Metallic properties and welding parameters of titanium Titanium has a small specific gravity (specific gravity is 4.5), high strength, good resistance to high and low temperatures, and excellent crack resistance and corrosion resistance in wet chlorine. The mechanical...Read more -
Take you closer to plasma arc welding
Introduction Plasma arc welding refers to a fusion welding method that uses a high-energy-density plasma arc beam as a welding heat source. Plasma arc welding has the characteristics of concentrated energy, high productivity, fast welding speed...Read more -
Do you know the rolling welding process
1. Overview Roll welding is a type of resistance welding. It is a welding method in which the workpieces are assembled to form a lap joint or butt joint, and then placed between two roller electrodes. The roller electrodes press the weldment an...Read more -
Welding tips Precautions for galvanized pipe welding
Galvanized steel is generally a layer of zinc coated on the outside of low-carbon steel, and the zinc coating is generally 20μm thick. The melting point of zinc is 419°C and the boiling point is about 908°C. The weld must be polished before welding The galvanized layer a...Read more -
Tips How to distinguish welding slag and molten iron during welding
During the welding process, welders can see a layer of covering material floating on the surface of the molten pool, which is commonly known as welding slag. How to distinguish welding slag from molten iron is very important for beginners. I think it should be distinguis...Read more -
Note that not all post weld heat treatments are beneficial
Welding residual stress is caused by the uneven temperature distribution of welds caused by welding, thermal expansion and contraction of weld metal, etc., so residual stress will inevitably be generated during welding construction. The most common method to eliminate re...Read more -
Why does the machine tool collide with the tool
The matter of a machine tool collision is not a small matter, but it is also a big one. Once a machine tool collision occurs, a tool worth hundreds of thousands of yuan may become waste in an instant. Don't say I am exaggerating, this is a real thing. ...Read more -
The precision requirements of each process of CNC machining center are worth collecting
Precision is used to indicate the fineness of the workpiece product. It is a special term for evaluating the geometric parameters of the machining surface and an important indicator for measuring the performance of CNC machining centers. Generally speaking, machining acc...Read more -
The Difference Between Surface Finish and Surface Roughness
First of all, surface finish and surface roughness are the same concept, and surface finish is another name for surface roughness. Surface finish is proposed according to the visual point of view of people, while surface roughness is proposed according to the actual micr...Read more
