Can american bureau of shipping's ABS welder qualification certificate be used nationwide? What happened when I went to the gas pipeline company to apply for a job with this certificate but was rejected? Can american bureau of shipping's ABS welder qualification certificate be used nationwide? The answer is no.

There are many kinds of welder certificates with different grades. For example, it varies according to the level of welding position. If you can pass the welding assessment of overhead welding position, you can carry out flat welding, but passing flat welding does not mean that overhead welding is qualified. That's the reason. Also, if american bureau of shipping sends you a welding certificate for the hull structure, it doesn't mean that you can weld pipes. The certificate of welding pipes may be different from the certificate you got, so it is normal to be rejected for a job in a gas pipeline company.
