What are the main advantages of the butt welder

11 Jan 2021

Butt welding machine 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 passed instantaneously to heat the contact surfaces of the two interface metals and instantly melt and fuse. Butt welding machine can be divided into flash butt welding machine, steel butt welding machine and copper rod butt welding machine according to different welding methods. Flash butt welding mainly uses the contact resistance of the workpiece to generate heat to heat the workpiece. The metal surface melts, the temperature gradient is large, and the heat affected zone is relatively small. The welded joint is formed under plastic deformation of the solid metal opposite to the workpiece. The structure and composition of the weld are close to the base metal (or after heat treatment), so it is easier to obtain equal strength plastic welded joints. The flash evaporation process has the eff...

Learn How To Weld

04 Jan 2021

Welding is a complex subject, and this article is far from being comprehensive on any aspect of it. However, one thing that it attempts to cover is a few absolutely necessary requirements and a number of basic beginner mistakes that one can easily avoid. As a quick introduction, the most frequently used and easiest-accessible welding processes are arc welding/gas welding (including tig welding and mig welding). Arc welding describes welding processes that use a welding power supply to create an electric arc between an electrode and the base material to melt the metals at the welding point. They can use either direct (DC) or alternating (AC) current, and consumable or non-consumable electrodes. The welding region is sometimes protected by a kind of inert or semi-inert gas, known as a shielding gas, and/or filler material. Arc welding is widely used because of its low capital and running costs. MIG (Metal Inert Gas) and TIG (gas tungsten arc) welding are kinds of gas metal arc welding. D...

Do you know the history of welding and manufacturing

28 Dec 2020

Today, when we use different complex welding tools, we need to understand the history of welding. We need to look back and see when to start welding. To know this, we need to go back to the Iron Age. At that time, the Egyptians and the Eastern Mediterranean began the welding process. They like to use this process to perfect the process of welding iron sheets into iron boxes. The hammer had not yet been invented. Hammers appeared in the late Middle Ages and were used to make other kinds of small iron products. They used to heat up until they got hot. When Edmund Davy discovered acetylene in the 1830s, the process became older, and welding with acetylene became much easier. It helps to identify the arc between two electrodes. The invention of arc lighting has made new improvements to the traditional welding process. In the traditional welding process, cutting and gas welding have become much easier than the previous welding. At that time, welding had become a popular joining process. Alm...

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 ...
