1.Welding materials
In
Welding, substances called filler materials or consumables are used. As the
name implies, these substances provide filler or a body of molten materials
that provides a strong bond to be formed between the base metals used. Most
welding processes will also require some form of shielding to protect both the
main components and filler from being oxidized during the process.
The
type of welding materials used during welding depends on the nature of the job
intended. Electrodes draw the necessary energy in order to perform welding
applications. Luoyang Golden Egret Company has any kind of welding materials
include CTC Welding Rod /rope, SCTC welding rod/rope, TC electronic welding rod,
Ni-based welding rod, flux-cored Welding Wires, solid welding wires and etc.
Welding
can be applied in different kinds of industries such as building and
construction, oil and gas, marine, power generation, steel, mine tools,
automobile, transportation and etc.

GS110650N
(CTC, 6mm, HRC 47-55)
4. Welding Bar
The
rod is sintered by CTC and Ni-based powders. The CTC(Cast Tungsten Carbide) is
in irregular or spherical shape with better wear resistance and the nickel
alloy is in spherical or nearly spherical shape and has good wettability with cast
tungsten carbide. The cladding layer has a higher impact resistance and better
wear resistance.
Its
wear resistance and corrosion resistance is between tube rod and flexible rope.
Mainly
used on the Steel PDC bit, Concrete mixer blade, Mud pump, Miner chute, Miner
drill stem and Mechanical parts of Tunnel rock drill machine etc.
Welded
by Oxy-Acetylene with weak carburizing flame.
Product
recommendation:
GD4025253-3(CTC, SCTC, 4*600/6*600)
GD4030303-3(CTC,
SCTC, 4*600/6*600)
5. Welding wire
Intensified molybdenum titanium vanadium
composite chromium carbide welding wire can improve layer`s bonding strength
and tenacity. This wire can use for multilayer welding which has no peel off,
and it can maintain good wear resistance under certain impact working condition.
Product recommendation:GSQD671Mo-4(1.6mm)
Medium carbon and high chromium wear resistance welding wire has a higher
hardness, stronger wear resistance, and excellent toughness by adding a certain
amount of molybdenum alloys and boride. It has a better impact resistance and
strip resistance than high chromium cast iron type materials
Product recommendation: GSQD621Mo-4(1.6mm)
With
high sphericity & excellent alloy organization, cemented carbide pellet is
mainly used in welding, as an adding material of PTA Powder , tubular welding
rod, to improve the wear resistance of the workpieces greatly.
Product recommendation: GQ06
Cemented
carbide grit with different percent of cobalt has good abrasive resistance and
is widely used for making grinding, polishing and cutting tools.
Product
recommendation: GS08A

According to reports, the Beijing-Shijiazhuang-Shiwu passenger line started construction in October 2008. After completion, it will connect the Wuhan-Guangzhou high-speed rail and Guangzhou-Shenzhen high-speed rail to form the Beijing-Shenzhen Passenger Dedicated Line in the "four vertical and four horizontal" rapid passenger transport network of China's railways. The national railway network has an extremely important position and role. It is reported that at present the main project of the whole line is basically completed, the project quality and construction safety have been effectively controlled, and all the preparation work for the operation has been carried out in an orderly manner, which has laid a solid foundation for realizing on-time opening operations across the board.
It is worth noting that the recent news of railway construction is slowly warming.
On the 18th, the Ministry of Science and Technology formally issued the “12th Five-Year Plan†for the development of high-speed train technology. On the 17th, Wang Mengshu, a railway expert, said that with the gradual arrival of funds, 80% of all railways have already resumed work, and 500 billion yuan of funds will be put in place this year, all of which support the construction of the railway.
In fact, at the end of last year, Sheng Guangzu had stated at the national railway work conference that according to the “Twelfth Five-Year Plan†and funding conditions, fixed assets investment was RMB 500 billion in 2012, of which capital construction investment was RMB 400 billion, and the new line was put into operation 6366. Kilometers.
For the future financing of railway construction, Sheng Guangzu said that it will increase the financing and management of railway construction funds. Actively strive for the support of the relevant state departments, expand the scale of railway construction bonds, increase the intensity of loans, make full use of various market-based financing tools, and further broaden funding channels.
In fact, from the fourth quarter of last year, the "financing hunger" of railway construction funds has eased. The Ministry of Railways not only received financing support of more than 200 billion yuan to ensure the repayment of projects under construction and the promotion of key projects, but also issued the first-phase railway construction bonds worth 20 billion yuan this year. The fiscal and taxation departments also successively issued policies such as “half the collection of corporate income tax on interest income from railway construction bonds†and “clearing the construction of railway bonds as government-backed bondsâ€. The market’s confidence in and recognition of the Ministry of Railways bonds has gradually increased.
At the same time, Sheng Guangzu said that he must also actively seek local government investment, attract private capital, expand the sources of railway construction funds, and provide continuous financial support for railway construction.
Experts believe that despite the tense situation in China’s railway financing last year, the financial market supporting railway construction has been relatively open and relaxed since the fourth quarter of last year, and the financial sector’s support for railway construction will continue.
Minister of Railways: Ensure the fulfillment of the "Twelfth Five-Year Plan" railway construction goals
Minister of Railways Sheng Guangzu recently emphasized the construction of the Beijing-Shijiazhuang-Shiwu Passenger Dedicated Line. He emphasized that all participating companies and operating units should invigorate their spirit, strengthen their confidence, overcome difficulties, and work together to build a high-quality, high-efficiency and efficient construction task to ensure that Jingshi, The Shiwu Passenger Dedicated Line is scheduled to open and operate to ensure that the “Twelfth Five-Year Plan†railway construction goals are fully realized as planned. This is the clearest statement made by the Ministry of Railways on railway construction this year.
