Previously, the main type of welding of metals was gas welding. But today, other types of welding, which are largely more technologically advanced,. Nevertheless, gas welding of metals is still an relevant solution in different industries. Why and what are the advantages of gas welding over arc and contact welding?
Gas welding process.
With the help of a special welding burner, the edges of metal products are heated to a half -melted state, and then as if merged with the help of tools. Cooling, two details become a single whole. This is a rather short way to describe this technology.
To heat the metal so that it melts, burning of combustible gas is required in a mixture with pure oxygen. The gas supply is regulated by the gearbox, and for each gas, its own type of gearbox is used and in no other way – they differ even by the appearance. For example, the oxygen gearbox is always blue.
Advantages that make gas welding competitive.
Why today they still use gas welding, despite the presence of more modern options? Everything is quite simple here – gas welding is the easiest way to welding. In addition, unlike other options, gas welding does not require the purchase of complex expensive equipment. By the way, electricity in gas welding is also not required and this is the third plus and advantage. Although, it is also worth noting that combustible gas and oxygen for gas welding will be released at a cost higher than the bill for electricity. But gas welding allows you to cook some types of metal better than arc welding.
It is also worth highlighting the fact that gas welding gives more options to the welder, which can adjust the rate of heating of the metal and its cooling. But, on the other hand, this very speed of heating is largely less than with any other type of welding. Heat is concentrated to a lesser extent, but the warning of the welding elements is higher. However, as many welders say, it is not a way, but in the skill of the one who does this work.
As a result, it turns out that, despite the shortcomings in comparison with arc welding or contact welding, gas welding still has advantages that help it keep a competitive struggle for a place in industry.
Equipment for gas welding is sold by the Doca Trade house. You will need oxygen and combustible gas, a filler wire, cylinders and gearboxes, burners, gas supply sleeves, generators. Do not forget to provide employees with welder glasses, special clothes and a number of tools.
