Q:What is welding wire? How to translate welding wire?

Welding wire and welding rod are welding materials, but the applicable welding method is different, SMAW welding method should use electrode, GTAW, SAW needs welding wire...In foreign welding standards, the standard English name for welding wire is "(Welding) Wire". The following paragraph is copied from the standards of the ASME. There is "welding wire" in it":

Q:Two how many kinds of wire welding equipment are needed? How much do you charge for a set? Thank you.

Two wire equipment needs pretreatment equipment, Mary eighth boron coated tank drawing machine, CNC precision pull straight wiredrawing machine, expansion of copper production line, winding machine can be produced; a set of 10 hours of production of 1.2 wire 3 tons of equipment prices in 550 thousand.

Q:72173090 is the HS encoding of the welding wire?

NoThe welding wire should fall under the 8311 item

Q:The role of silicon in stainless steel welding wire

Silicon (Si) in the main role in the stainless steel wire have: the solid solution strengthening effect, improve the resistivity (good for welding deposition efficiency of hot wire welding), reduce hysteresis loss, improve permeability, improve hardenability, anti tempering brittleness, to improve the comprehensive mechanical properties, high elastic limit, corrosion resistance increased the favorable natural conditions, content is higher, lower solderability, and easily lead to cold brittle.At the same time, a certain amount of silicon can also increase the fluidity of the deposited metal and the corrosion resistance of the wire.Everything is on the current US There are both advantages and disadvantages., a three generation nuclear power construction, the main pipe of the nuclear level equipment reactor uses the original welding wire is 316LSi, the wires have been bought, but in the process of evaluation, were told to not be used, and replaced with 316L or 316LN, while a variety of reasons, different experts there are different opinions. After all, nuclear power is no small matter, the use of wire containing Si is very common at present, but in the nuclear level of important items, we have no right to decide on it.

Q:Two welding machine, 1 of the welding wire into 1.2 of the need to change where?

The welding torch changes the electric nozzle, the wire feeder changes the wire feed wheel.Welding torch, electric nozzle, 0.81.0 dual-use, need to replace wire feed wheel.The conductive nozzle is 1.01.2, which is used directly in the feed rotation surface.A 1.2 mm tip (tip diameter than the wire diameter 0.02 mm, the actual tip diameter of 1.22 mm diameter) conductive nozzle wear too much need to replace the nozzle.

Q:What kind of gas shielded welding wire for Q345 steel plate?

Carbon steel welding wire for Q345 steel using ER50-6 gas shielded welding.ER50-6 is a kind of carbon steel welding wire for gas shielded welding. It has excellent plasticity, toughness and crack resistance, especially low temperature impact toughness.Application: it can be used in various positions of pipes such as manual tungsten inert gas arc welding, grounding and arc welding, and satisfactory welding joints can be obtained. Weldable carbon steels and certain low alloy steels.

Q:What is the relation between Jing Lei welding wire and Beijing group welding wire?

One family. Beijing group is the name of the company, Jing Lei Shijing group company product trademarks.

Q:What's the recycling of the wire tray for?

Recycling, if there is no damage, then do a I frame, G force clean, like new

Q:What does "GHS-70" wire mean?

GHS-70 is a 700Mpa grade high strength steel welding wire, which has excellent comprehensive mechanical properties. GHS-70 adopts mixed gas, it can weld the low strength alloy steel structure of corresponding strength level, and is widely used in the welding of hydraulic support and scraper chain wheel of coal mine machinery.The welding wire is made of H08Mn2SiA wire rod steel, drawn and treated by surface copper plating. It is used as CO2 gas shielded welding wire, with less spatter and good anti porosity performance.Application: Welded low carbon steel and some low alloy steel structure.The chemical composition of welding wire (%) C = 0.11 Si:0.65~0.95 Mn:1.80~2.10 = 0.20 Cr Ni = 0.30, S = 0.030, P = 0.030, Cu = 0.50Electrode diameter: 0.8, 1, 1.2, 1.6, 2, 2.5, 3.2 (mm)Attentions: clean the oil and rust on the surface of the workpiece before welding, and select the suitable welding specification.

Q:Why is welding wire plated copper?

The main purpose of copper wire welding is corrosion protection, because the main component of the wire is steel, and the bare leakage is easy to rust and corrosion in the atmosphere. The surface coating of copper can effectively prolong the shelf life. Furthermore, electrical conductivity can be enhanced.Welding wire is used as filler metal or metal wire welding material at the same time as conductive. In gas welding and gas tungsten arc welding, welding wire used as filler metal; in submerged arc welding, electroslag welding and MIG arc welding, welding wire as filler metal, and conductive electrode. The surface of the wire is not coated with anti oxidizing flux.
