I welcome everyone. You are on the channel for self-taught beginners in welding and proper work with a grinder. A shaped pipe is the most common material for welding at your site or in the country.
Why is the professional pipe the most in demand? The construction of this material will be strong but lightweight. All this is due to the thin walls of the pipe itself.
The thickness of these profiles is 1.5-3 mm, but the most purchased for the house is still 1.5 or 2 millimeters. But these advantages of the material for the novice user with an inverter create one problem.
If you cook with a solid without separation, then the beginner will have frequent burns. And even experienced ones will not always be able to weld the joints of the professional pipe only with a solid, often it is necessary to combine welding with a separation and a solid. But only for a beginner, it is better to cook point by point, gradually depositing a weld on the pipe joint.
But even here, for a beginner without experience, another difficulty lies in wait. This is the right purchase of electrodes for this kind of welding with frequent breaks. Not all electrodes can weld point by point. Let's look at it now.
To weld a profile pipe with frequent separation in a hardware store, you need to buy electrodes with a rutile or rutile cellulose coating.
These electrodes can weld not only with frequent pull-off point by point. They are also unpretentious to the welded metal surface. If there is old paint, dirt, even rust on the surface, such electrodes will still burn and weld
Welders often refer to these electrodes as rutile or rutile electrodes. So, with this we figured out, and what brands of such electrodes should we buy in a hardware store?
Friends, pay attention to these stamps. They are time-tested and are quite suitable for household welding in terms of price and quality. This is ;
ANO-21
MP-3
MONOLITH
OK-46
This is the best choice. There are of course many other brands, but this can be said to be a classic!
So write down or memorize these 4 marks, it will be enough for a beginner to start.
