Why does a home technician use welding technology?
In fact, the welding technology is to create permanent joints of metal parts with the help of a welded seam. When welding at home, most often you may need the following types of joints: angled, butt, overlap, T-shaped, slotted;there are many others.
self-welding work is performed most often with the help of gas, electric arc welding or inverter welding. But before starting work, you need to learn the basic safety rules. Do not work with faulty or poorly insulated equipment.
And also it is not necessary to weld or cut designs that have just been painted. Do not weld containers that are pressurized or contain combustible flammable substances. Work should be carried out in a protective mask and overalls.
Welding work with your own hands - preparation and safety of
Before you start this kind of work at home, you need to get a welding machine and the necessary tool, as well as to conduct some preparatory welding work. Any type of welding at home will require a welding machine, electrodes, a protective mask with a spherical filter, dense protective clothing, a hammer, a metal brush.
It is better to have a welding machine with a smooth current regulation, which will allow smooth adjustment of the current depending on the diameter of the electrodes used and the density of the parts to be welded. Since welding technologies assume the use of different diameter electrodes to perform certain tasks, it is better to stockpile all kinds of electrodes in sufficient quantity.
After this, it is necessary to wear protective clothing that protects against sparks on the skin and to prepare a mask that will protect the eyes during operation. According to safety regulations, all flammable substances must be removed from the workplace and a bucket filled with sand.
Welding at home - how to get the right seam?
To begin with, you should acquire welding skills, training on unnecessary details. It is best to use the most common type of electrodes with a diameter of 3 mm. It must be strengthened in the electrode holder. After this, you need to adjust the current strength of your machine in accordance with the type of welding seam, the air temperature, and the diameter of the electrode used.
The electrode is exposed to the workpiece at an angle of approximately 70 °.Then you need to touch the electrode parts, carving a spark. After lifting the electrode over the workpiece, an arc should be formed about half a centimeter in height, which melts the metal of the electrode. The electrode, melting under the action of the arc, will fill the gap between the parts to be welded, creating an all-in-one connection, so it is necessary to carefully guide the electrode in the direction of the welded seam.
Sometimes the electrode can stick to the metal - this is the first sign of insufficient current. To do this, the electrode must be torn off and adjusted the welding current. If this is not done, the welding machine may fail. Then you need to light the arc again. The main thing that should be learned is to maintain the active arc stably.
After the seam has cooled, it should be knocked on it with a hammer, discouraging scale and brushing it with a metal brush.
For conducting serious welding work, you should master the reading of welding drawings. Independent welding works, the video-guidance of which is attached at the end of the article, is a simple process, but requires certain knowledge and skills.
