Where to start when learning electric welding machines for beginners?

Personally, I think you should learn how it works first, so that you can think about safety and how to maximize the benefits, and what you weld can meet your needs as much as possible.

It takes about three months for a novice to learn electric welding.

Electric welding generally takes about one to three months to learn before you can reach the entry level. Those with strong learning ability and high understanding can reach the entry level after one month of study, and those with poor learning ability will need three months. Generally, the welding apprentices are from the foundation to their own operation, the time is generally 3-5 years, because the apprentices are through the way of the master with the apprentice, at the beginning are mainly seen, rarely operated by themselves, that is to say, the opportunity to practice is very few, and often many apprentices are still confused after learning for many years, so the learning time is relatively long.

Areas of application for electric welding.

Welding technology is widely used in the industrial sectors such as aerospace, aeronautical cracking, nuclear industry, shipbuilding, construction and machinery fabrication and shedbuilding, and is an indispensable means of processing in China's economic development. After entering the 21st century, welding is an important part of the manufacturing industry, and the rapid development, so it has brought unprecedented development opportunities to the welding industry. <>

How do you learn to be a welder?

We need to know what electric welding is first? Electric welding is a welding operation that uses the welding rod to melt the metal parts at high temperature through the arc to the place where they need to be connected.

If you want to learn electric welding, you should first learn mechanical drawing, be able to understand drawings and welding symbols, understand how to weld, etc., and master the material structure, welding principle, operation process and actual operation methods and testing.

When welding, the welding rod and the iron plate are kept at an angle of 45 degrees, which is conducive to the uniform distribution of molten iron, and the weld is smooth.

When welding, the hand needs to be kept stable and welded, and the arms must be clamped to avoid shaking, so that the welding can be uniform and beautiful. When welding, it is generally used to weld zigzag and dot type, so that the welded seam texture is clearer.

When performing the upward welding operation, because the molten iron is easy to fall, it is necessary to take the form of spot welding, so that the sintering will be more firm. At the end of the circle, when the electrode is moved to the end of the weld, it should move in a circle at the arc pit until the arc pit is filled and then the arc is broken.

When the electrode is replaced or the arc is stopped temporarily, when the electrode is moved to the end of the weld, it stops at the arc pit for a short time, slowly raises the arc, and then leads to the base metal groove at the edge of the weld. At this time, the molten pool will gradually shrink, and there will generally be no defects after solidification.

The above are just the basic theoretical knowledge and skills of electric welding, but these need to be mastered slowly in theoretical and practical teaching, and skillfully complete a process of technical requirements.

In this process, first of all, we must learn with an open mind, remember the key points of the technology, the difficulties, and the techniques needed in welding, and the basic knowledge must be learned and practiced by heart in order to meet the basic requirements of welders.

Learn mechanical drawing first.

Able to read drawings.

Understand welding symbols.

Only then do you know the welding, how many welding angles, how the weld is and so on. Including: material structure, welding drawing, welding principle, structure and working principle of various welding equipment, manual arc welding, gas welding, gas cutting, argon arc welding, carbon dioxide gas shielded welding operation process and practical operation methods, as well as various welding quality testing.

Welder is a special type of work, arc light to human eyes and ** if not protected will be harmed, just welded weldments do not wear good gloves to move will burn hands, knock welding slag if not protected will also hurt people. At the same time, the operability of welders is very strong, and most people want to learn welders well, the reason why some people lose interest is because people feel that the effort is not proportional to the progress of the welding level, coupled with the damage of the arc to the eye or the damage of the weldment opponent pushes these people away from the door of learning.
