With the development of society and economy, the improvement of people's living standards
and the changes in the structure of civil fuels,
liquefied petroleum gas as a highly efficient and clean fuel together with gas cylinders has entered millions of households.
Liquefied petroleum gas is also a kind of flammable and explosive compressed gas,
and the cylinder containing the gas is a mobile pressure vessel.
The safety issue is very important, and ensuring the manufacturing quality of the cylinder is important to ensure the safe use of the cylinder. premise.
The key quality characteristics of steel cylinder manufacturing quality are:
The quality of the main material of the cylinder
Cylinder volume quality
Cylinder heat treatment quality
Bottle valve quality
The quality of the main ring weld of the cylinder
Welding is an important process in the manufacture of gas cylinders and has an important impact on the quality of gas cylinders.
Therefore, the welding process must be strictly controlled.
VIDEO CASE
The current problems of gas cylinder manufacturers:
Big error
Taking LPG cylinders as an example, due to the cold forming of thin steel plates, errors in the blanking process are inevitable;
during the splicing welding process, the accuracy of the fixture and manual placement will also cause errors, which can lead to welds.
The location is not accurate.
Low production efficiency
At present, most of the steel cylinder welding uses a girth welder with a worker to watch and manually adjust the position of the welding torch.
Poor production quality and safety
Workers with high labor intensity, fatigue or distraction will lead to low consistency and stability.
At the same time, the welded steel cylinder is likely to cause the bottle to explode during the pressure test,
which will increase the production cost and seriously threaten the personal safety of the operator.
The welding of the main welds of gas cylinders is the main factor that affects the production and quality of gas cylinders.
The connection between the upper and lower heads of the cylinders is the girth weld.
Therefore, automatic welding should be used for welding.
The purpose of automatic welding is to ensure the stability of the weld quality, because the gas cylinder is a mass-produced product,
and only automatic welding can maintain the continuous stability of the weld quality.
The ATINY laser welding seam tracking system can be used in gas cylinder welding to realize high-precision tracking and rectifying weld seams,
improve the yield rate of gas cylinders, and improve the comprehensive competitiveness of gas cylinder manufacturers! Contrast effect before and after the use of laser automatic tracking technology during the circumferential seam welding of gas cylinders: Welding operation:
From "one person, one set of equipment" to "one person operating multiple sets of equipment at the same time". Welding process:
From "bottle loading, manual calibration to start welding, welding torch is not adjustable" to "bottle loading, one-key start, real-time tracking, real-time welding torch adjustment". Weld characteristics:
From "undercut, accumulation, pits, partial arc, welding leakage" to "full and uniform welds, no undercuts, offset welding, pits, accumulation". Welding process:
From "programmed welding, the welding speed cannot be controlled" to "control the welding speed according to the width of the weld seam, fill the gap, and accelerate the small weld seam". Requirements for artifacts:
From "high-precision perfect circle, no deviation, high drawing precision requirements" to "any roundness error workpiece, the existing drawing process can be used". Requirements for staff:
From "welding workers with mature work experience" to "workers only need to load and drop bottles, no requirements". Rate of qualified products:
From "unstable, about 80%" to "stable, about 95%" (solve series of welding defects caused by partial arc).
