I welcome everyone to the channel for beginners in the garage and dacha self-taught welding. Here we share welding work tips to shorten your path to normal results.
The fillet seam for beginners is one of the most insidious. When welding, it begins to fill the weld pool with slag and it often turns out that the metal sticks to one of the walls. To avoid this and the seam turned out as in the photo above, follow these tips.
Let's weld this corner joint. Here, 2 strips 5 mm thick are tied. We take electrodes with a diameter of 3 mm with a rutile coating, OK-46 00. Reverse-plus polarity of the inverter on the holder with an electrode. We will select the correct welding current.
The devices are all different and give out different welding currents, so we select it quite simply, despite the recommendations for amperes in the welding tables.
Take an unnecessary piece of metal with the same thickness. We set approximately the required current, light the electrode on this piece of iron and very slowly we conduct it without oscillatory movements.
We look for the seam to spread as much as possible on the metal in width. Then we take 2 electrodes and compare the end with the coating with the width of the adjustment seam. We add or decrease the current on the apparatus until the width of the seam is equal to about 2.5 coated electrodes.
This will be the correct current for welding the fillet. Such an arc energy will be enough to drive off the oncoming slag well and well boil both shelves in the corner joint. Now the movements of the electrode themselves.
We light the electrode at the beginning of the corner, make the arc a little longer and warm up both shelves. Here we are in no hurry to move on immediately. It is necessary to wait for the formation of a weld pool - a spot of molten metal, which will connect both shelves. Now let's start moving the tip of the electrode, see how it is correct.
Now, from the heated weld pool, we move the electrode along the lower shelf to a distance of about 2/3 of the electrode diameter, let part of the electrode remain in the weld pool.
Now, with a movement in a semicircle, we will go back a little and go to the upper shelf, pull the electrode to the border where we stopped on the lower shelf.
And thus, over and over again, the removal of the electrode from the weld pool along the lower shelf and rounding back with movement along the upper one to the border of the pool on the lower one.
This way we form a weld with the same advance speed. There will not be slag or metal sticking to one of the shelves. The result with this fillet weld method is always excellent. Let's see what happened.
The slag rose with a rocker over the seam, gently pry it with the end of the electrode and it easily separated from the seam in one layer. So the seam is okay, it's good. Let's see.
Let's enlarge the photo for clarity. The fillet weld is nice, flake to flake. No slagging, both shelves are evenly welded. The method works!
