What welders need to know2

1. Welding Environment Factors

These factors include environmental factors, environmental protection, and labor protection awareness, as well as their impact on the welding process. For example, pay attention to the effects of rainy and humid weather on welding techniques and weld defects.

There are also the impacts of pollution and safety in the welding environment on people. Thirdly, there are the harmful effects of smoke, dust, and spatter, as well as the impact of bad habits on the body.

2. Cultivate Strong Operator Skills

Many welders focus solely on completing their work quickly, neglecting to develop sound operator skills. This leads to fatigue after work and slows down their technical progress. How can one achieve strong operator skills?

First, in addition to mastering basic welding theory, one must also understand relevant knowledge about metal materials and weld pool characteristics. During welding, pay close attention to the shape of the weld pool and select the correct welding rod feeding method and angle to achieve a good weld.

Of course, a good welder also fully understands the role of each body part, skillfully selecting the appropriate welding posture and utilizing the functions of each body part.

For example, using the wrist to control the rod's swing to ensure weld width, and using the elbow to control the rod feed speed, etc. Coordinating all body parts will create a comfortable welding posture and naturally reduce physical exertion.

3. Fully understand the role of each body part in welding.

During welding, the welder's eyes, elbows, waist, wrists, and other parts of the body all play a role and should be used appropriately.

For example, the eyes primarily serve as an observer during welding. It's difficult to observe changes in the weld pool from both near and far distances, which can easily lead to visual errors, resulting in a chaotic weld pool and unsightly welds and defects.

Similarly, the elbows play a feeding role in welding; the body or waist should not be used to replace this feeding action. The wrists play a role in oscillating the welding rod. The width, frequency, and pattern of the weld are determined by the wrists; oscillation of the welding rod should not be achieved with the elbows.

Therefore, welders should fully understand the role of each body part. On construction sites, it's common to see welders using their bodies to feed the welding rod, requiring the welder's entire body to be pressed against the welding rod. This is not only unsightly and prone to burns, but can also damage the lumbar and cervical vertebrae.

Many welders suffer from lumbar and cervical spine diseases at a young age because they do not develop a good welding position and posture.
