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.

GT3302 (carbide pellets, 20-40mesh)
GT3302-1(carbide pellets, 14-40um)
4)The hard phase of the rod is monocrystal WC,
the welding layer has a higher wear resistance and better impact resistance.
The wear resistance is 6-7 times better than
others, tested by ASTM G65 method.
Mainly used for the repair and strength for oil
drills bits, such as PDC bit diameter holding by Oxy-Acetylene with weak
carburizing flame.
Product recommendation:
GT4104 (Monocrystal WC, 80-200mesh)
3. Welding Rope
Made
form mixture of CTC and self-fluxing nickel alloy covering on nickel wire. The
CTC is in spherical or irregular with good wear resistance; the nickel alloy is
in spherical or nearly spherical shape with good wettability and erosion
resistance and better corrosion resistance than tubular rod.
Recommend
to use Petroleum drilling tools, Concrete mixing blade, Mud pump, Coal sluice,
Coal drill pipe, Tunnel drilling machinery etc.
By
Oxy-Acetylene Welding with weak carburizing flame.
Product
recommendation:
GS110450N
(CTC, 4mm, HRC 47-55)
GS110550N
(CTC, 5mm, HRC 47-55)
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

[China Instrument Network Instrument R&D] Recently, the newly established electro-acoustic standard device of the Institute of Metrology, Jining City, Shandong Province, passed the on-site assessment of the experts of the evaluation team of the Shandong Provincial Bureau of Quality and Technical Supervision, which filled the Jining City’s capabilities in electro-acoustic measurement and inspection. blank.
With the development of economy and the improvement of material and cultural living standards, environmental protection work has become increasingly important. Noise has become an important indicator to measure the economic development and ecological harmony of a country. Sound level meter (noise meter), noise statistic analyzer, and sound calibrator are instruments used to measure the sound pressure level or sound level of a sound. The “Measurement Method†lists it in the mandatory test list, which is the most The basic and most commonly used instruments are not only used in acoustic and electroacoustic measurements, but have also been widely used in various fields such as machine manufacturing, architectural design, transportation, environmental protection, medical and health, and national defense engineering. Noise and noise surveys are carried out in an all-round way in life and production. The machine manufacturing industry places noise as one of the important quality indicators of products. Auditoriums, theaters, stadiums, and other buildings require not only beautiful shapes but also sound effects. These all make electric sound The use of measuring instruments has become more and more extensive and has become an essential electroacoustic measuring instrument.
Jining City, the new electro-acoustic standard device for measurement testing, can carry out the scope of detection include: one, two sound level meter; one, two noise analyzer; one, two sound calibrator. The establishment of this standard device has filled the gaps in the compulsory verification of electroacoustic fields in Jining City, and provided accurate acoustic equipment for use in the fields of machine manufacturing, architectural design, transportation, environmental protection, medical and health, and national defense engineering. Reliable technical support and support.
