The selection of welding rods must be based on the chemical composition, mechanical properties, plate thickness and joint form of the material to be welded, the characteristics of the welding structure, the stress state, the structural use conditions, the requirements for the performance of the weld

Whether you're a professional welder or not, you need to protect your eyes and skin from harmful UV rays, heat, sparks, and radiation while welding.The goggle and a helmet all have advantages and shortcomings.While goggles are lighter and less cumbersome, they only offer protection for the eyes. Helmets will protect your eyes and the rest of your face, but they are bulkier and more confining.

The welding of copper and stainless steel is often encountered, and the welding is difficult. The main performance is that it is very sensitive to the penetration crack of copper during welding. ; The second is to choose the appropriate filling material, control the elements that are prone to low-me

Flux is a granular welding material. It melts to form slag and gas during welding, and plays a protective and metallurgical role for the molten pool. When welding, it melts to form slag and gas, and acts as a protective and metallurgical treatment for the molten metal.CompositionFlux is composed of

Water jet cutting uses nozzles to produce a high pressure water jet carrying fine abrasive particles for cutting. This method is very effective in cutting both metallic and non-metallic materials. The process uses high capacity pumps with very high water and electricity requirements. This method can

Hot-rolled and normalized steel in low-alloy high-strength structural steel and alloy structural steel species with a low total content of alloying elements, and the mass fraction of carbon is generally less than 0.25%. Therefore, on the whole, the weldability is better. The general strength level i

Many methods of joining stainless steels are able to be applied well to ferritic stainless steels, mainly including.(1) Melt welding By melting the base material and the filler metal after recrystallization so that the two or more materials separated from each other to achieve a complete bond.(2) So

Heat exchanger, as the heat transfer equipment that transfers part of the heat from the hot fluid to the cold fluid between materials, has a wide range of applications in people's daily life and in petroleum, chemical, power, pharmaceutical, atomic energy and nuclear industries. It can be used as in

When welding with tungsten arc welding equipment, the following steps should be followed.① Turn on the main power source, cooling water source and gas source, and check if they are in normal condition.② Switch the switch in the welding power source to the "on" position and the welding changeover swi

Welding can choose AC welding machine, can also choose DC welding machine. When using a DC welder, there are positive and negative connections, taking into account factors such as the welding rod used, the condition of the construction equipment and the quality of the weld.Compared with the AC power
