What are the welding equipment? Which one is better?

There are many kinds of pipeline automatic welding equipment, first of all, there are gas shielded welding, argon arc welding, submerged arc welding, and three welding methods of their own combinations. There are also many kinds of automatic welding machines, such as: flat welding flange automatic welding machine; Split pipeline automatic welding machine; Split backwall pipe automatic welding machine; Cantilever chuck type pipeline automatic welding machine; Cantilever chain type pipeline automatic welding machine; Gantry pipeline automatic welding machine (gantry mobile); Clamp type pipe automatic welding machine, etc., if you need anything, you can consult Shanghai Qianshan Pipeline.

You can go to Xin Fangsheng or Fangsheng Yuncai** to take a look, these categories of goods are very complete, you can compare them carefully.

The following brands are relatively good and can be selected according to personal needs:

1. Purnell ZX7200 household electric welding machine.

This small household welder from Punell is lightweight and compact, making it ideal for home use. With a 270-degree current adjustment knob and a lengthened copper core power cord, the speed of its intelligent "chip" seven-leaf fan can reach 4100 rpm, which is not possible for general brands. And its transformer technology is very good, with low loss characteristics, energy saving, high efficiency, and ** is also very affordable.

2. Songle ZX7-200 all-copper core small household welding machine.

The small household welding machine of this brand in Songle has a very high cost performance. The control board is a single-board integration process, which reduces the looseness of the electronic wires when connected, and greatly reduces the failure rate of the machine. Super soldering circuit environment, damage is easy to repair.

The transformer adopts an EI ferrite all-copper all-enclosed structure transformer, and no amount of iron filings can enter the transformer. Its radiator is very powerful, with good heat dissipation performance and a strong service life.

3. Pulijie household mini welding machine.

The highlight of this household welding machine is that it is smaller than ordinary household welding machines, and the body is very small, so it is not afraid to move at any time. The metal shell is strong, drop resistant, and wear-resistant. The blue design is easy to identify, and it has the function of safe use identification.

All copper quick interface, divided into left and right design, clear marking, easy to plug and more user-friendly design. Although it has a small body, it has a large function, is easy to carry, and has a strong welding force.

4. Weishi ZX7-250 all-copper core household electric welding machine.

This welding machine from Weishi is also a good choice for everyone. The original capacitor is used, the service life is longer, and the transformer uses amorphous veneer, which has ultra-low loss characteristics, saving energy and efficiency. The segmented radiator design fixes the IGBT tube directly on the surface of the radiator, which has higher heat dissipation efficiency and prolongs the service life.

Hello, to learn new energy vehicle major, it is recommended to go to the school that specializes in automobile training to study, the professional school is three points of theory + seven points of practice teaching mode, you can go to the school to visit and then determine.

Here are a few ways to distinguish a good technical school, you can take a look:

1. It is recommended to choose public schools in developed areas, which have a long school running time and a long school running time is more reliable. First of all, click on the school's official website to observe the school's campus situation, check the school time, and whether it is a group school.

3. Look at the management and teaching level of the school, which is the foundation that determines whether you can learn the technology, and the teaching level includes professional settings, teachers, teaching facilities, project training, etc.

4. Looking at the size of the school, a good school is generally about 1,000 to 3,000 people, and there are more vocational schools with more majors, but it is not necessarily good.

5. Employment security, whether the school arranges jobs, whether there is a career guidance center, how many family units have cooperated with them, etc.

Precautions: It is best to visit the school after choosing a school, don't choose in a hurry, after all, it is a turning point in life, don't easily believe how good those things are said, you have to see and hear it, it is true.
