Do you know the type of welding
21 Dec 2020
Stick welding is a slang term for "Shielded Metal Arc Welding" and is commonly abbreviated, or referred to, as "SMAW". The slang term comes from the rod that is used because it is looks like a stick. This is a process that uses a power source that produces constant amperage to create an arc. This type of welder uses a rod, or electrode, made of metal with a flux coating on the outside that protects the weld area from the air while the rod is burning. SMAW is mostly used in the field because it is a practical welding process that is cheap, works great on most metals, and allows for welding thick materials. This makes it an excellent joining process for most industrial construction needs. SMAW is also the most basic form of welding that is taught in the majority of schools as foundation to learning other types of metal joining processes. TIG welding, or TIG, is an abbreviation for "Tungsten Inert Gas" but its proper name is "Gas Tungsten Arc Welding" commonly abbreviated and referred to ...
What are the main uses of the pipeline welding machine
14 Dec 2020
What are the main uses of the pipeline welding machine? The so-called pipeline welding machine is used when installing pipelines for it. Nowadays, there are more pipeline products on the market. Each kind of pipeline has its own characteristics. The role played in the market is not small, and the same is also a product that is demanded in life. When the pipeline welding machine is developed in the market, it is generally more promising. Only in this way is the pipeline welding The machine can be better based on the market, and at the same time it can be more stable. 1. Pipeline installation It is necessary to scrape the welding machine when installing the pipeline. At this time, the pipeline welding machine is a tool for use. When people install the pipeline, they need to use the pipeline welding machine. , Because this type of product is already a relatively mature product in the market, it is more risky for people to choose a new product for installation, so you still need the help o...
What are the steps for hot melt butt
09 Dec 2020
Large-diameter PE water supply piping systems are mainly connected by hot-melt butt joints; small-diameters are connected by hot-melt sockets; when connecting with metal pipes and other pipes, flange connections must be used; small-diameter pipes can also be connected with steel-plastic transition joints; Where the location is special and the construction is more difficult, electric melting can be used for construction. Hot melt butt installation Hot melt butt welding is to use a hot melt butt welding machine to heat the pipe ends (hot melt butt joint temperature is 210+10°C). After the pipe ends are melted, they are quickly laminated, maintaining a certain pressure, and cooling to achieve the purpose of welding. Applicable pipe diameter range: dn≥90mm Steps: 1. Put the two PE pipes to be installed and connected on the fuser clamp at the same time (the clamp can be replaced according to the pipe diameter to be installed), and the other end of each pipe is lifted to the same level with ...
What are the precautions for the operation of the welding machine
30 Nov 2020
Butt welding machine(https://www.chbuttfusionweldingmachine.com) is also called current welding machine or resistance welding machine. Using the resistance between the contact surfaces of the two workpieces, a low voltage and large current is instantly passed through, so that the contact surfaces of the two butting metals instantly heat to melt and fuse. Key points of operation of butt welding machine: 1. The operator of the butt welding machine has been trained to be familiar with the structure, performance, and operating procedures of the butt welding machine, and master the knowledge of process parameter selection and quality inspection specifications. 2. Before operation, check whether the various mechanisms of the welder are sensitive and reliable, whether the electrical system is correct, whether the cooling water pump system is leaking, and whether the lubricating parts are well filled with oil, etc. 3. It is strictly forbidden to butt-weld steel bars with a diameter exceeding t...
Introduction to the components of the seam welder
23 Nov 2020
Seam welding is a type of metal welding that forms a bond. During welding, the weldment is pressed between the two welding wheels, and the welding wheel is rotated to drive the weldment and energized. The welding current locally generates heat through the weldment, forming successively overlapping welding spots to form a continuous weld, realizing sexual welding. Light reaction is used for seam welding of tanks, such as automobile and motorcycle fuel tanks; barrels, such as oil drums, and formed sheet workpieces, such as wheels, mufflers, radiators, etc. The seam welding machine control box is controlled by two single-chip microcomputer systems respectively to control the welding procedure and the electric heating process, so it can quickly transform various special resistance welding machines, and can also be transformed into a special controller for various high-power three-phase low-frequency heating power supplies. So the three-phase low-frequency spot and seam welder control box c...
What is the structure of the butt welding machine
16 Nov 2020
The structure of the butt welding machine is mainly composed of welding transformer, fixed electrode, moving electrode, feeding mechanism (pressurizing mechanism), water cooling system and control system. The left and right electrodes are respectively connected with the conductor of the welding transformer's secondary coil through a multilayer copper skin, and the welding transformer's secondary coil is cooled by circulating water. There are protective plates on both sides and under the welding place to prevent molten metal from splashing into the transformer and switch. The welder must frequently clean the metal splash on the protective plate to avoid short-circuit and other faults. 1. Feeding mechanism: The feeding mechanism can complete the melting and extrusion process required in welding. It mainly includes a joystick, a movable cross frame, an adjusting screw, etc. When the joystick is moved between the two poles, the electrode can be work plan. 2. Switch control: Press the butto...
