The welder is used when the current bottom can not spark is anything to cause
- 1, the use of welding machine, the current does not hit the end of the spark because of loose joints, there is poor contact place.2, welding machine is also called current welder or resistance touch welding machine. By using the resistance between the two workpieces' contact surfaces, the contact surfaces of two mutually butted metal can be instantly heated, melted and fused instantaneously through a low voltage and high current.3. Welding is suitable for wide range. The metal material which can be forged in principle can be welded by flash butt welding. For example, low carbon steel, high carbon steel, alloy steel, stainless steel and other non-ferrous metals and alloys can be welded by flash butt welding. Welding section area is large, generally from tens to tens of thousands of mm2 cross sectional area can be welded. Flash butt welding is widely used in welding various kinds of plate, pipe fittings, profile, solid parts, cutting tools and so on. It is widely used and is an economical and efficient welding method.s
What's the butt welding machine? What's the difference between it and welding?
- Butt welding machine belongs to series of resistance welding machine. Broadly speaking, it also belongs to the category of electric welding machine.The upper and lower two water cooling electrodes are used for pressurizing, and a large current is used for a short time to cause the electrode to touch the parts to produce a nugget, and the no-load voltage is lower, so that the melting of the electrode and the bonding of the base metal are avoided. A welding process to the effect of welding.Narrow sense electric welding machine refers to the welding rod hand arc welding machine. Of or belonging to a fusion electrode (a welding electrode used as an electrode and fused and filled to form a weld). The no-load voltage and the working voltage are relatively high. The no-load voltage is high, easy to arc; the work voltage is high, easy to electrode (welding rod) melting. And ensure the weld penetration.s
380V 150KVA flash butt welder, what kind of cable do you need?
- The wire diameter is usually calculated according to the following formula:Copper wire: S= IL / 54.4UAluminum wire: S= IL / 34UIn style:I - the maximum current (A) passed through a wireL - the length of the wire (M)U - permissible power drop (V)S - cross sectional area of the conductor (MM2)So, you know what material and how long wires can be used to determine how much cable you want.s
For welding with steel wire, what method do not let it break
- Why reply immediately?s
Construction site, welding machine, welding machine, tower crane, people, goods, ladders and so on, add up to about 4500W of power, how many thick cables?. It should be about 350 meters
- Is it 380V or 220V? How many KW are there for an electric welder?s
What kind of power supply is common for welding machines used on site?
- 1. If you already have a welder, you can calculate the data according to the welding machine nameplate data. The power supply of the welder is usually single-phase 380V, multiplied by the nameplate, and the I1max is the maximum power of the welder;2. If you do not have a welder, please refer to the answer on the first floor.s
How many KW generators will be needed for the steel bar welding machine used in the railway engineering construction?
- At least 300s
Can the coil in the welder be connected to the joint? Does this affect the power of the welding machine?
- Yes, it doesn't work. The thread is not around the magnets
