Steel Structure Welding Taboos And Prevention Measures
During the welding process of steel structure, there are many matters to be paid attention to. Once neglected, it may lead to a big mistake. The following content is the items that are often ignored in the process of steel structure welding, don't be careless Welding construction does not pay attention to choose the best voltage phenomenon, danger When welding,
The Difference Between Ordinary & CNC Face Milling
Applications Of Face Milling Face milling machine The end face milling machine is used for milling the end face of welded or rolled h-beam steel or box beam, and can also be used for processing the side of h-beam steel or box beam and cylinder. The face milling machine system is mainly composed of the face milling machine host and hydraulic worktable. The Difference Between Ordinary Type &
How to control welding in sub-zero winter?
Entering winter, the environment temperature is low, if there is no protective measures to welding steel components, welding quality of steel components will have a significant impact. For example, welding at low temperature will make the steel embrittlement, but also accelerate the cooling rate of the weld and the heat affected zone of the base metal, which is easy to produce the hardened structure and increase the brittleness, which is very harmful to the welding of low-alloy steel commonly used in building ste
H - beam production machine, choose vertical or horizontal?
Horizontal production line H-section steel production line (horizontal) can assemble steel plates into H-section steel, and then welding after a special welding production line, and ordinary H-section steel vertical welding production line, it has higher production efficiency, and when welding, the deformation is relatively small.
How to control welding in sub-zero winter?
With winter coming, the environment temperature is low, if there is no protective measures to welding steel components, welding quality of steel components will have a significant impact. For example, welding at low temperature will make the steel embrittlement, but also accelerate the cooling rate of the weld and the heat affected zone of the base metal, which is easy to produce the hardened structure and increase the brittleness, which is very harmful to the welding of low-alloy steel commonly used in building steel structure (such as Q345). Therefore, winter welding cons
Welding rotator operation rules and precautions for use
As a welding auxiliary device, the welding rotator is often used for the rotating work of various cylindrical and conical welding parts. It can cooperate with the welding positioner to realize the inner and outer circumferential seam welding of the workpiece. The welding rotator is also constantly being improved, but no matter how it is improved, the operating procedures for the welding rotator are basically the same. I
Safety operation rules for H-beam assembling machine
Equipment introduction A single assembling machine is composed of main machine, trolley case, input roller table, output roller table, electric control box, operation box, hydraulic station and other departments. The wing plate, web plate, clamping centering, positioning, automatic spot welding and
Complete equipment for steel structure production line
1. CNC plasma flame cutting machine CNC plasma/flame cutting uses a digital motion control system to realize motion by writing a processing program in the system or transferring processing files or graphics, combined with a stepper or servo motor driver, and driving the stepper or servo motor to control the machining axis of the machine too
Basic structure and working principle of welding rotator
In the welding production process of the special vehicle, the welding of the tank body is inseparable from the use of the welding rotator. Before starting the operation, the staff are generally required to be familiar with the basic structure and performance of the welding rotator to ensure the production efficiency. I
What are the advantages of welding positioner?How to judge the quality of the positioner?
In modern industrial production, the application of robots is very common, especially in welding operations, many production lines use welding robots, but only welding robots cannot complete all welding work, so welding positioners are generally equipped to make It becomes the external motion axis of the welding robot, so what are the advantages of using the welding positioner? How to judge the quality of the positioner when choosing?
Summary and analysis of eight defects in welding
The quality defects existing in welding engineering mainly include the following aspects: all defects that can be seen by the naked eye or a low-power magnifying glass and located on the surface of the weld, such as undercut (bite), weld bead, arc crater, surface porosity, pinch Slag, surface cracks, unreasonable weld positions, etc. are called external defects, and internal pores, slag inclusions, internal cracks, incomplete penetration, and infusion, etc., which must be discovered by destructive testing or special non-destructive testing methods, are call
Ten common problems of shot blasting machine
According to Zhouxiang`s experience, we found below 10 common problems in shot blasting machine running: I. The dust of the dust collector contains too much projectiles If the air volume of the separator is too large, properly adjust the tuyere baffle until the dust removal effect can be ensured, but it is better not to suck out the projectiles.
High-efficiency horizontal H-beam automatic production line
The H-beam horizontal production line can be a set of special welding production lines that can be assembled into H-beams and then welded. Compared with ordinary H-beam vertical welding production lines, it has the characteristics of high production efficiency and small welding deformation, which is especially suitable for The production of light H-beam steel is widely used in steel structure, construction and other industries.
Solutions to problems in the air pipe of the CNC flame cutting machine
The gas pipeline of the CNC flame cutting machine provides a stable and continuous fuel supply for cutting. In order to ensure the verticality and flatness of the cutting surface in terms of cutting quality, the pressure, flow and purity of the gas supply have corresponding requirements. Some common gas circuit failures and solutions during daily use: First of all, the gas circuit failure we are talking about is the failure of the gas pipe and gas circuit except for the parameters of gas pressure, flow and purity
How to ensure the stability of fiber laser cutting machine performance
The laser cutting machine is a kind of advanced equipment, the price is generally very expensive, often tens of millions, but its ultra-fast processing speed is favored by many processing industries, then, if you want to give full play to the performance of the laser cutting machine, What should we pay attention to? The laser cutting machine also has a lot of precautions in daily maintenance. Pay attention to the following matters to ensure the stability of the laser cutting machine's performance!
Reasons for the decline of laser cutting machine cutting efficiency
In the current metal manufacturing industry, cutting has changed from traditional knife cutting to laser cutting. After a period of use, many customers have reported that the cutting effect and cutting ability of laser cutting machines are not as good as before, so the cutting efficiency of laser cutting machines What is the reason for the decline? Reasons for the decrease in cutting efficiency of laser cutting machine:
