2.IWE certificate. As a welding major, if you want to engage in welding work in the future, you'd better get an IWE certificate at school, because students can take the exam, but you need to have four years of welding-related work experience after graduation, which means you can take the exam after graduation instead of taking the exam at school. This card may not be needed, but I think it is best to have it. You can pay attention to the website of Harbin Welding Training Center /en/. They cooperate with some universities to hold training courses every year, but you can also go to Harbin, Beijing or Shanghai to take the exam, if you have time.
3, CAD certificate is actually dispensable, this certificate is actually useless, of course, it is better than nothing, as long as you master one or two of the three drawing software CAD, Pro-e and UG, which are basically the same, and you can learn from each other quickly. You should also master one or two professional 3D drawing software, such as CATIA.
Welding major. After graduation, my major is welding technology or welding design. The most important thing is to engage in craftsmanship, because designing requires certain experience and level. Generally speaking, you won't ask undergraduates to do this. Welding technology includes welding procedure qualification, compiling welding documents, training welders and providing welding technical support for other departments. Different companies do different things. Welding requires you to have rich experience, and what the school teaches you is too theoretical, so generally speaking, you will not find a well-paid job just after graduation. It takes you at least four or five years to accumulate. Welding develops rapidly, such as laser welding and friction stir welding. And the things in the school books are just. Although you may not find a well-paid job at first, in fact, other majors are the same, but as long as you work hard, the future is beautiful, believe me.
