the New heat-resistant steel welding performance
Familiar with the comparison of several welding consumables and welding process, select ALCromocord92 (AirLiquideWelding / of Oerlikon) ThermanitMTS616 (Bi3hlerThyssenWelding) Chromet92 (MetrodeProductsLimited) three kinds of mature P92 steel hand-welding the deposited metal test, initially on P92 manual arc welding rod of steel were evaluated.
Three kinds of welding materials appropriate technology can be satisfied with the weld metal, but because of subtle differences in the design concept and composition, making the process performance have their own characteristics. MTS616 to take the steel core of the alloying elements transition, while the remaining two kinds of alloying elements, the drug skin transition, due to the melting point of W particles in the drug skin up to 3410 ° C, the welding energy is too small, it is possible the phenomenon of mixed metal W . Therefore, two types of electrode process should be different for the latter type of Welding Electrode , not just one-sided emphasis on the small line energy to improve the weld impact energy. P91 steel weld metal inclusions appear similar reasons, less, because the melting point of Mo is nearly 800 ° C lower than w.

Quality inspection is divided into two, a check for the self-test, level check for the final inspection. Self-test includes: preparatory work; before the Welding Electrode baking; posts permit inspection of welding personnel, welding procedures execution; one by visual inspection of welded joints. The self-test member must be a welder served by a narrow gap through specialized training in technical excellence and strong sense of responsibility.
Final inspection by the professional quality inspection departments, carried out are: the welded joint on-site visual inspection one by one, randomly selected specimens in the field, mechanical performance test conducted by the laboratory, the specimen is generally extracted three for tensile test. The need may also be taken of three specimens for cold bending test.
Extracted from the installed steel mesh specimen difficult, you can create mock trial, the location of the specimen and welding procedure specifications must be consistent and on-site construction conditions. Inspection with reference to hydraulic concrete construction specifications (SDJ207-82).
In order to ensure the quality of the inspection sub-standard connectors, such as: undercut, incomplete penetration, not welded full welding or plus tie bar welded reinforcement processing.

A, laser engraving machine is the most common laser engraving equipment, laser engraving effect has a uniform color, a clear pattern, durability and other characteristics, is commonly used in wood carving, mobile phone shell carving. Different material has its own characteristics and these characteristics tend to use different laser engraving method.
Second, different materials for the sculpture, we must first study the properties of these materials, to select a different power of laser engraving machine. For wood, first, wood is the most commonly used materials are generally easy carving, so long as the good wood hard to debug can. Color plates is necessary with the sentence of its material to choose, the color plates there is a more than two color composite structure consisting of an engineering plastic, is usually used in processing instructions signs and badges, if the surface color is very thin , it is necessary to acquire a small piece of debugging. Plywood sculpture key depends on the kind made of wood. There will be a wood engraving after burning had the feeling, the depth of its color mainly depends on the laser power and engraving speed. Dongguan laser marking machine
, Laser engraving machine is often based on the needs of different users, in metal, wood, glass and other products for rugged carved scriptures, pictures, digital graphics, the reason of this is also a wide range of laser engraving equipment applications.

Laser cutting machine equipment more and more mature as a new tool applied to a variety of industries, including laser cutting machine, laser engraving machine, laser marking machine, laser welding machine. The laser cutting in the end is how the use of laser cutting is good or bad, how to distinguish it? First, the laser energy in the form of light is concentrated into a beam of high-density beam is passed to the work surface, generates enough heat, so that the material melting, combined with the high-pressure gas of the beam coaxial directly to remove the molten metal, so as to achieve the goal of cutting This shows that the laser cutting machine tools machining is essentially different. It is the use of the laser beam emitted from the laser generator, and focused into the optical system, high power density laser beam conditions, the laser heat is absorbed by the workpiece material, workpiece temperature rose sharply to reach the boiling point, the material begins to vaporize and form holes , accompanied by high-pressure air flow, with the beam and the workpiece relative position of the mobile, the final material to form the kerf. The kerf of the process parameters (cutting speed, laser power, gas pressure, etc.) and the trajectory by the CNC control slag slotted at a certain pressure of the auxiliary gas blowing.

Laser cutting machine laser beam parameters, the machine performance and accuracy of the numerical control system have a direct impact on the efficiency and quality of laser cutting. Especially for the cutting of high precision or the thickness of the larger parts, we must grasp and address the following key technologies: a focus position control technology: One of the advantages of laser cutting beam of high energy density, the general 10W/cm2. As the energy density is proportional to the 4/πd2 the focus spot diameter as small as possible in order to produce a narrow kerf; deep is proportional to the focus spot diameter and the lens focus. Focusing lens depth of focus of the smaller focus spot diameter is smaller. But cut a splash, the lens away from the workpiece too close to the lens easy to damage, so 〃 widely used in industrial applications of the general high-power CO2 laser cutting machine 5 \"to 7.5\" (127 ~ 190mm) focal length of the actual focus spot diameter of 0.1 to 0.4 mm. for high-quality cutting, the effective focal deep and the lens diameter and the material being cut. such as cutting carbon steel 5 the 〃\\ s lens, depth of focus is within +2% of the focal length, that is about 5mm, so control focus relative to the position of the cut surface is very important to take into consideration the cutting quality, cutting speed and other factors, in principle, 6mm of metal materials, the focus is on the surface; 6mm carbon steel, the focus is on the surface; 6mm stainless steel, the focus beneath the surface of specific size determined by experiment.
