To become an international pipefitter, you need to complete a training program and an apprenticeship, during which you learn the skills you need to fulfill your responsibilities. Pipefitters have experience with the tools of their trade, such as threading machines, welding torches, and grinders. Your qualifications should also include the ability to read and understand diagrams and blueprints, and strong troubleshooting and problem-solving skills are an asset. Many states require pipefitters to be licensed; licensing requirements vary, so make sure to check the criteria in your state. For these international positions, you must also be flexible and willing to spend weeks or months overseas. After working at least four years, you can become a certified pipefitter, which may make you more competitive in the job market.
