Does that know how a welder learns, is the process of learning steps?

If you want to teach yourself, you have to learn metal material heat treatment and drawing and junior fitters, welding textbooks, and finally practical operation, to learn to first weld groove plates, welding pipes, vertical welding, back welding, gas cutting, proficiency can do this line.

Rely on you to learn too, I advise you not to come, there are too many people like this now I am also 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.

I've been a welder for 10 years now, and I didn't know anything when I first learned it. Fortunately, the welding rod and materials in my factory can be used casually, I will take the welding handle to find the feeling, now it is an intermediate worker, in fact, this thing is nothing, as long as you can pick up the welding handle, don't be afraid of arc light and welding slag hot, bold welding, you can find the feeling in less than two days, and then you can step by step, first thick plate flat welding, then thin plate, vertical welding and vertical welding and finally learn. Don't rigidly learn other people's movements, how to do what you are comfortable with.

Also pay attention to safety, to prevent electric shock, the no-load voltage of the welding machine is only about 70 volts, but the current is very large, we must pay attention to the damage of the wire and the welding handle do not touch the body. I hope it can help you, and I wish you a speedy recovery. You are very welcome to come to me, we are all together.

The point is to be safe!

If you want to learn to be a welder, you need to go to a formal institution to do a professional training and obtain a welder certificate before you can take up your post.

An electric welder is a person who operates welding and gas cutting equipment to weld and cut metal workpieces.

It is mainly done in schools or factories.

The method of learning must be combined with theory and practice in order to learn this technology.

Disclosure is a job related to a project related to electric welding.

Welder refers to the use of electric welding to operate workers can go to technical schools to learn welders when studying.

What exactly does a welder mean? Basically, if you have those rigid iron welds, those welds are done by these welders, and if you want to learn, you have to go to school.

Welder is a kind of machinery manufacturing and machining operations, in the processing and manufacturing industry is a very important job, at present, China's processing and manufacturing industry is very lacking in this area of talents, although the welder work is hard, but the salary is better, so many older people will choose welder training, so as to enter the welder industry.

Now people who choose to learn welder technology are more able to endure hardship, because this industry cannot endure hardship. Now there are fewer and fewer people who can endure hardship, which further improves the remuneration of the welder industry. In addition, the technical requirements of the industry are also relatively strong, so the salary package is generally better.

What kind of welder training school is better in Chengdu?

Learning technology, in fact, everyone's criteria for judging good or bad are different. In Chengdu, it is advisable to conduct a field trip when looking for a welder training school, and it is recommended to conduct an inspection from the following points:

1.Faculty. First of all, it depends on whether the school's teachers are strong, what are the qualifications of the teachers hired, and how many years of experience they have.

2.Industry experience. Look at the experience of the training school, whether you have just done this training, or have accumulated a certain amount of training experience, and whether the project construction is mature.

3.Curriculum. Understand whether the school's curriculum is scientific and reasonable, and whether the content taught meets the market demand.

4.Hands-on training. Look at the school practice training, learning technology, especially welder technology, must be more operations and more practice in order to master it solidly.

In short, we can look at welder training schools from many aspects, and it is very important to choose a welder training school that suits you and can really learn the technology.

The quality of welding plays a decisive role in the quality of the product, so what is the future development of welding technology?

First, the industry prospects.

With the development of production, welding is widely used in aerospace, aviation, nuclear industry, shipbuilding, construction and machinery manufacturing and other industrial sectors, in China's economic development, welding technology is an indispensable means of processing. 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.

At present, China consumes 300 million tons of steel every year (about tons of welded structure), and needs about 750,000 welding machines, and the welding industry will continue to grow in the next 8 10 years.

Second, advantages. 1. This major does not have a high status in the society, but this major still has good development prospects in the future.

2. This major is very suitable for boys, and it is very unsuitable for girls, because the strength of girls cannot meet the requirements.

3. Professional prospects.

The prospect of welding is very good, and welding is widely used in industrial sectors such as aerospace, aviation, nuclear industry, shipbuilding, construction and machinery manufacturing. In China's manufacturing industry, welding is an indispensable means of processing, but the current number of welding talents is far from meeting the employment needs of the society, especially the extreme lack of talents in arc welding, carbon dioxide protection welding, argon arc welding, etc., which has created a large demand for welding skills, urgent demand and high salary.

Fourth, expansion, basic knowledge.

The basic form of deformation is common.

The basic forms of common welding deformation are as follows: the deformation of the length shortening (longitudinal shrinkage) and width narrowing (transverse shrinkage) caused by the butt welding of the plate groove; angular deformation after butt welding of the plate groove;

The angular deformation of the component after welding is different along the longitudinal axis of the component and the distortion deformation caused by the inconsistent longitudinal contraction of the flange and the web of the component;

After the thin plate is welded, the compressive stress area of the base metal causes the wave deformation caused by warping due to instability; Due to the asymmetry of the longitudinal and transverse contraction of the weld relative to the neutral axis of the component, the overall bending of the component is called bending deformation.

An electric welder is a special metal welding job in the machinery manufacturing and machining industry, and is a person who operates welding and gas cutting equipment for welding and cutting forming metal workpieces.

Learning electric welding is mainly in the school system, about the knowledge of electric welding and the specific operation methods.

Learning electric welding is a good craft, because there are certain technical and skill requirements, and the effect and quality of the products welded by welders of different levels are quite different. Really high-level welders (national level) salaries are high. It's this that is harmful to the body.

In fact, welders are also a special type of work, and they can go to some qualified training centers to obtain certificates.

If you want to learn, you have to go to some schools to sign up.

If he is a welder, you can go to a place that specializes in doing this kind of work, and you have to go and learn to be an apprentice.

1: First of all, learn what you need to work; Before learning electric welding technology, I should have an idea, what company I want to enter, I need to learn electric welding or carbon dioxide gas shielded welding or argon arc welding, which positions to learn, whether it is flat welding, flat fillet welding or horizontal welding, vertical welding, vertical welding, and vertical welding. If you learn it, you can apply it in your work, and you should be targeted.

2: Practical training: welders should learn well, mainly six words "diligent study, more thinking, hard practice", with hard training as the most important, through hard training to master the skills taught by the coach, standardize the basic movements.

3: Practice should be concentrated continuously: three days of fishing and two days of drying nets is not good to learn welders, only let go of the mentality of eagerness, step by step, in order to really learn the skills, really use a lifetime.

4: To learn from a high-level teacher: what is a high level, you can go to a school with better equipment, teachers and other conditions, this kind of school is relatively strong.

5: Before welding, we should carefully study the theoretical knowledge of welding, think while welding, and constantly summarize experience, so that the technology will progress.

Theory is one thing, but the key is to practice more and focus on practice.

1. Vertical welding should use a welding rod with a finer diameter than flat welding and a smaller welding current or flame to reduce the volume of the molten pool and make the molten pool temperature not too high, so as to reduce the flow of metal in the molten pool.

2. Short-arc welding is used to shorten the transition distance from the molten droplet to the molten pool.

3. When welding, try to shorten the arc or flame heating the workpiece, and do not stay at a certain point for too long. When the arc or flame forms a molten pool on the weldment, the electrode is moved up or to both sides, so that the arc or flame is temporarily removed from the molten pool (non-extinguishing arc), which is conducive to the cooling and solidification of the deposited metal, and then the electrode is moved back.

4. Correctly select the angle of the welding rod (the left and right directions are 90°, and the vertical plane below is 60°-80°, and the blowing force of the arc or flame is used to push the molten pool upward, which is conducive to the transition of molten droplets and supports the molten metal.

5. Generally, it is welded from the bottom to the top, and when welding thin parts (less than 3mm), it can also be welded from the top to the bottom. Gas welding is generally from the bottom to the top, but when underwater electric welding, it should be welded from the top down.

Learn how to weld well:

If you start from scratch, first through the Internet, books to understand the basic theory of welding technology, after a certain foundation began to seek practice, you can go to the relevant private stores, factory workshops to do free or low-return apprentice help, during the period to know the relevant technicians, and finally choose a technical type as a mentor and friend, find a mentor and friend after insisting on operation practice, began to use the way of consulting to solve problems, and slowly evolved into a first-class progress, and finally stick to you can also be a teacher.

Learn the basic concepts of electric welding:

According to the basic requirements of welders, it is simple and clear, easy to understand, and describes the composition, classification and use of welding equipment and commonly used tools and measuring tools, welding rods, arc welding of welding rods, welding safety and protection, etc. Welding rods, welding machines, and welding appliances need to be paid attention to, and safety is the first for electrical grounding before welding. The welding tongs should be held steadily, the solder joints should be accurate, the success or failure of the arc is in an instant, flat welding, vertical welding, diagonal welding, submerged arc, argon arc are fully displayed, and the electric welding work is not difficult to understand the drawings and practice.

Really high-level welders (national level) salaries are high. It's this that is harmful to the body. 2. The welder welds on site for safety.

Protective equipment must be worn in accordance with national regulations. There are many protective equipment for welders, mainly including protective masks, helmets, protective glasses, noise-proof earplugs, safety helmets, overalls, earmuffs, gloves, insulated shoes, dust masks, safety belts, gas masks and shawls. 3. There are more than 100 welding methods, mainly manual welding (that is, the kind of welding rod); There is resistance butt welding; Gas shielded welding (carbon dioxide and argon arc welding, etc.); flame welding; Ultrasonic welding, friction welding, etc.

The more commonly used welding techniques are: argon arc welding, carbon dioxide welding and manual welding. All need to go through formal welding training and obtain a welder certificate before they can be operated.

Learn electric welding to come to Wantong Hunan Wantong welcomes you!

You have to find a professional school to learn from the basic system and do more hands-on practice.

Learn by heart and practice more. You can learn well, and you must become a master if you combine theory and practice.

Combining theory and practice; Theoretically, it is necessary to familiarize yourself with the equipment used: the type of welding machine, the characteristics of welding materials [electrode, solder]; What are the basic techniques? What are the welding processes?

Wait a minute. In practice: to practice squatting, arm strength, wrist strength and so on.

Welders belong to special work, and the first thing to do is to understand the relevant regulations on safe operation.
