How to learn welding technology well?

1. First, know what you need for your job; Before learning welding technology, I have to have an idea. If you want to enter any enterprise, you need to learn welding, carbon dioxide gas shielded welding or argon arc welding. I need to know which positions to learn, whether it is flat welding, flat welding or horizontal welding, vertical welding or overhead welding. After learning, it can be applied to work, and it is highly targeted. If you don't use it, you will still forget it.

2. Practical training is preferred: welders should learn well, mainly six words "study hard and practice hard", and practice hard is the most important thing. Through hard practice, they can master the skills taught by the coach and standardize the basic movements.

After 2-4 months of preparation, you can really learn skills and really benefit for life.

It is important to find the right teacher. A good teacher can lay a good foundation for you and make you inexhaustible.

5. Before welding, we should seriously study the knowledge of welding theory, practice thinking while welding, and constantly sum up experience, so that the technology will progress.

Welded joint A welded joint is formed by welding two or more parts. The welding structure usually consists of several welded joints. According to the structural shape of joints, welded joints can be divided into five categories, namely butt joints, T-joints, lap joints, angle joints and end joints.

Arc welding technology In order to ensure the stable combustion of welding arc and the formation of weld surface, after the arc is ignited, the covered electrode will move in three directions.

(1) The coated covered electrode continuously feeds the welding pool.

(2) covered electrode moves forward along the welding direction.

(3) When covered electrode swings horizontally and covered electrode moves, it should form an included angle of 70-80 degrees with the forward direction, and push the molten metal and slag to the rear, otherwise the slag will flow to the front of the arc, resulting in slag inclusion defects. In order to obtain a wider weld, covered electrode must swing in the process of feeding and moving. Common strip conveying modes are: (1) linear strip conveying mode (2) linear reciprocating strip conveying mode.

(4) Sawtooth transportation method.
