In some settings, however, working conditions are much better and there are few hazards or discomforts. Overtime is sometimes necessary to complete special projects. They should be able to concentrate on detailed work for long periods and be able to bend, stoop, and work in awkward positions. In addition, welders need to be adaptable, as it is becoming increasingly common for welders and cutters to receive cross-training for other production jobs. The Armed Forces operate welding schools as well.
Some employers provide training to help welders improve their skills.
Courses in blueprint reading, shop mathematics, mechanical drawing , physics, chemistry and metallurgy are helpful. A knowledge of computers is gaining importance, especially for welding machine operators, as some welders are becoming responsible for the programming of computer-controlled welding machines, including robots. Some welders become certified, a process whereby the employer sends a worker to an institution, such as an independent testing lab or technical school, to weld a test specimen to specific codes and standards required by the employer. The testing procedures are based on the standards and codes set by one of several industry associations with which the employer may be affiliated. If the welding inspector at the examining institution determines that the worker has performed according to the employer's guidelines, he or she then certifies that the welder being tested is able to work with a particular welding procedure.
