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.

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

The main way for buildings to receive lightning strikes:
(1) Directly hit mine. Direct lightning strikes the lightning directly on the object. The thundercloud close to the ground induces an opposite charge on the protrusion. When the electric field strength between the thundercloud and the ground protrusion reaches the air breakdown strength, it will strike. Wear discharge, this type of thundercloud directly puncture discharge on the ground protrusion is called direct lightning. High buildings and their sides are subject to direct lightning strikes, and direct lightning strikes on the side of a building may be called side impact mines.
(2) Induction of thunder. Lightning strikes a conductor, such as a metal object next to the device, and indirectly strikes the object. Lightning induction is divided into electrostatic induction and electromagnetic induction.
The following measures should be taken to prevent the above buildings from being attacked by lightning:
The power box and circuit board should be grounded. The grounding wire should be solid and reliable. The grounding resistance should be ≤ 0.1Ω.
The wiring should be correct and reasonable. Power lines and signal lines should be placed indoors to avoid outdoor wiring as much as possible, and to avoid the same direction and cross wiring with metal pipes, gas pipes, etc., and to avoid the same wiring with metal pipes, gas pipes, etc. The distance between the two should be ≥ 5 meters. . The wiring should be laid in a straight line to minimize bending wiring.
The power box installation location should be properly selected:
(1) Avoid installing on the side wall of the house, especially on the side wall of the projected house, so as to prevent direct lightning strikes.
(2) Avoid installation on the side of a pipe where there is a metal pipe or a gas pipe. In particular, it must not be installed on a side wall that is less than 5 meters away from the metal pipe and the air pipe.
In the lightning protection project in Henan, the buildings and building intercom doors are outdoors, and the possibility of being struck by lightning is relatively high, causing great inconvenience to the users and causing great economic losses. Through the investigation and analysis of the causes of these lightning strikes, the main components of the crash are the power box, circuit board, and talker.
