According to the Bureau of Labor Statistics, factory workers involved in assembly and fabrication make an average of $28,580 per year. This breaks down to approximately $13.74 per hour.
Earnings may vary based on factors such as previous experience, industry, location and the complexity of machinery to be used. In 2012, fabrication was projected to experience a slow growth rate of 4 percent over the coming decade. A high school education is generally sufficient for employment in the field, but some industries may require additional training. While many factory workers are involved directly in fabrication and assembly, additional positions to consider include management, machinery maintenance and logistics.
