The choice of shielding gas is important as well as the choice of adding materials, equipment and high qualification of welder. The right choice of shielding gas determines mechanical properties as well as a form of weld, spatters and slag at welding. We offer you certified shielding welding mixtures CORGON®. It is mixtures on the basis of argon, which are developed for obtaining significantly better results in comparison with welding in pure carbon dioxide.
Welding mixtures CORGON® have significant advantages comparing to carbon dioxide.
The best quality
Mechanical properties of weld depend on type of shielding gas. The application of shielding gas mixtures CORGON® reduces amount of oxide impurities and crushes grain thereby improving the microstructure of metal. High fatigue strength, less number of spatters and surface slag, better form are the weighty arguments in favour of CORGON® gas mixtures.
Better shape of weld and details form.
Weld strength and impact elasticity are higher.
Level of heat input is lower.
Amount of spatters is reduced as well as number of cleaning operations.
Amount of surface slag is reduced. It is easier to prepare surface for painting or zinc coating.
Absence of any sharp bends and stress raisers.
Level of risk of thin-walled details burn-through is lower.
With the help of CORGON® mixtures your company may increase the welding productivity more than twice because of higher welding speed in comparison with CO2. Insignificant amount of spatters and surface slag in many cases excludes the necessity of post-welding treatment.
The possibility of welding at high speed.
Shorter terms of complete product production.
Usage of expensive welding wire is more economical.
There is no need in regulator heating.
There is a high stability of arc.
Wide range of adjustments.
Less defects. Even less skilled welders demonstrate good results in welding.
Companies, changing from carbon dioxide to CORGON® mixtures, reduce their welding costs. This is the result of more efficient productivity and less volume of post-welding treatments. Gas cost contains only small part of general costs for welding. In all cases welding speed increase and weld quality improvement justify the additional expenditure.
Better labour conditions
Finished weld is not only one criterion for choice of any method of welding. Market conditions force companies to find any advantages over competitors such as higher speed of welding, cost reduction as well as labour conditions improvement. CORGON® welding mixtures not only shield a weld but also improve labour conditions, which has positive impact on welder’s health.
Decrease of welding aerosols gross extraction, smoke and noxious gases
Long-term exposure to smoke and welding aerosols can lead to silicoses of lungs, the professional disease of welders. Emissions measuring have indicated that certified CORGON® mixtures reduce mass extraction of smoke, vapor, metal oxide and soot in 2 or 3 times in comparison with inexpensive carbon dioxide. It means that there are in 2 or 3 times less harmful impurities in respiratory organs of welder. The main component in CORGON® mixture is the chemically neutral argon, which does not have any harmful effect on health.
Decrease of noise level and dustiness of working area
We used to the fact that welding and cleaning are closely connected. There is intolerable noise and extreme degree of dust level during cleaning, and any kinds of personal protective equipment don’t help. At the same time, correct mode adjustment and high quality CORGON® mixtures don’t allow spatters to be formed even during usage of old domestic welding semiautomatic devices. In some cases there is no need in cleaning after welding.
