Welding Camera Apply in TIG Plasma Welding and LCD Camera Monitor for Welding Line Dynamic Range Image + 140 dB, The Ds30 Can Acquire Images with a Great

High Dynamic Range (HDR)

With a dynamic range image + 140 dB, the DS30 can acquire images with a greater range of tonal detail than any standard camera.
This is particularly important for welding processes where there is a very bright light source in the image that needs to be seen in great detail as well as the darker surrounding background features.

Color When You Need It

With HDR color imaging, the DS30can acquire color images for various welding processes, such as GTAW, where color provides extra information such as: the boundary of the Heat Affected Zone, oxidation of the melt pool and tip, and shielding gas presence. The very bright weld arc can be seen in color without saturation as well as its darker surround- ing background features.

Welding cameras traditionally have been employed to aid automated or mechanized welding of inaccessible joints and ensure the integrity of critical welds.
      Cameras are practical tools for many other welding applications, too, now that recent advances in electronics have enhanced the image quality and reduced the price of such equipment.
Welding cameras are particularly useful for improving working conditions, weld quality, set-up speed, positioning accuracy, and facilitating quality assurance.
++ Welding Cameras Use In Automated Welding Procedures
From job-shop manual welding to push-button automated welding, fabricators employ a wide range of automation techniques to improve productivity and weld quality, as well as to ensure a welder's health and safety.  Relatively simple circumferential and linear joint-seams are often welded using positioners, rotators, column and booms, seamers, lathes, tractors, orbital welders, etc. Such equipment may use sensors to automatically control the process (automated welding), or the operator may manually control the movement and/or torch (mechanized welding). 
In either case, a clear view of the weld pool can significantly benefit the welding operation.
++ Applications and Benefits of Cameras in Automated Welding
The use of camera systems in automated welding arose from necessity.  Welding in hazardous environments subject to nuclear radiation, vacuums, lasers, argon, or water entails the use of welding cameras to control the torch head remotely and wire feed positions as well as to monitor the welding process. Welding cameras provide similar benefits in automated applications with restricted access (including bore cladding, orbital welding, and welding at height) or joints subject to preheating
++ Weld Quality Inspection In Real Time
In addition to positioning the torch before and during welding, cameras may be used as a real-time post-weld inspection tool by positioning the camera for views of the solidifying weld pool.In many cases, welding cameras are applied to monitor the welding of critical joints or expensive materials. For these applications, the cost of failure is significant, and the ability to take pre-emptive action is essential. 
++ Improving Welding Speed And Accuracy
However, welding cameras are no longer restricted to the most sensitive and expensive welding operations. Advances in camera electronics have improved image quality and reduced purchase costs, such that welding cameras now prove beneficial to many more automated welding applications. For example, a magnified view of the electrode and torch helps improve the set-up speed and accuracy of automated micro TIG and PAW, dabber TIG, and tube mill applications.  The performance of mechanical joint tracking systems is enhanced by camera supervision. Cameras applied to carriages facilitate welding upside down, at height, inside confined spaces, and around circumferential joints. 
Automated systems with multiple weld-torches, like those used to manufacture turbine shafts, welded I-beams, spiral tubes, and tanks, may be effectively monitored and controlled from a single console.

1. Preface of electrode electroslag surfacing:

The inner surfaces of reactors, reactors and thick-wall pressure vessels of nuclear power plants in the petrochemical industry require large area surfacing welding of stainless steel linings that are resistant to high temperature, oxygen and hydrogen sulfide corrosion. In the 1970s, in this field, a large number of domestic and foreign use of electrode submerged arc surfacing (SAW) technology. The width of the band pole is also developed from narrow band to 60mm, 90mom, 120mm, 150mm broadband direction. This technology has made great progress in dilution rate and deposition speed compared with submerged wire arc welding.

However, with the increasing size and high parameterization of pressure vessels, surfacing welding technology has been developed in a higher quality and more efficient direction. electrode electroslag surfacing ,Electroslag surfacing technology with electrode has been developed rapidly and widely in recent years because of its advantages of higher production efficiency, lower dilution rate and good weld formation than that of submerged arc with electrode.

Electrode electroslag surfacing is a highly efficient surfacing method, which is divided into two types: electrode submerged arc surfacing and electrode electroslag surfacing. Due to the use of thin plate type wide electrode and high welding current, so its melting speed is more than ten times to dozens of times of various monofilm welding melting speed.

2. One of the differences between Submerged Arc Strip Cladding (SASC) and common submerged arc welding SAW is that the welding wire is changed to a strip electrode. The arc is created between the strip pole and the workpiece. Flux flux is used to form a slag to protect the weld pool and help form a smooth weld surface.

3. Electrode electroslag welding

Electrode electroslag surfacing is the resistance heat caused by the liquid slag as a heat source. First, the arc is ignited between the electrode and the base material. The heat generated by the slag melts the surface of the substrate, and the edge of the electrode is immersed in the slag and flux. After the arc heat melts the flux to form the slag pool, the arc heat transitions to the resistance heat of the slag. The melted metal has a high density and sinks to form a liquid metal molten pool. The slag has a low density and floats above the molten pool. The slag pool is covered with the metal molten pool to protect the metal molten pool. Then the electrode continues to melt, the liquid metal and slag in the molten pool are rising continuously, and the lower liquid metal far away from the heat source is cooled and condensed into a surfacing layer.

Compared with submerged arc surfacing with pole, ESW or ESSC has the following characteristics:

ALSO IS electrode electroslag surfacing.

(1) The melting rate was increased by 60%-80%. (See picture below)

(2) Because the penetration is very shallow (about 10% to 15% dilution rate), only half of it is diluted to the base material.

(3) Welding low voltage (24-26 V).

(4) Large current and current density (60mm wide welding belt through the current is l000-1250A, the corresponding current density is 33-42 A/mm2), especially the high-speed flux allows the welding current to exceed 2000A, the corresponding current density is 70 A/ram2.

(5) The welding speed is increased (50%-200%), resulting in an increase in the coverage area.

(6) The heat input is roughly the same.

(7) Low flux burn loss (about 0.4-0.5kg /kg strip).

(8) The curing rate of ESW welding weld metal is very low, which is conducive to porosity escape and reduce porosity defects. Oxygen can escape from the molten electroslag pool to the surface; The metal surface of the surfacing layer is quite clean, which reduces the tendency of thermal cracking and intergranular corrosion from a metallurgical point of view.

In the practical application of industrial production, electrode electroslag surfacing is very important that the weld surface of the product has a higher melting rate and a lower dilution rate than the base metal. Submerged arc surfacing with electrode has been widely used in large surface surfacing, but electroslag surfacing technology is gradually taking the dominant position.

System working principle
   A laser is used as a light source to emit a certain wavelength of laser light onto the surface of the weld, forming a laser strip which is received and imaged by a HD camera at another location. After a series of algorithms, the 3D features of the weld are converted into images, generating structured information about the position and shape of the object being measured. This provides the robot with the path it needs to guide the welding process.
It is characterised by high accuracy, contactless and high speed.
