A certified welder is someone who has gone through a formal training program for joining materials together. These materials are typically metallic, such as steel, aluminium or brass, but can also be plastic or polymer-based.
The greater the experience, the higher the salary. PayScale states that as of September 2010, the median pay for welders with one to four years of experience is £9 per hour and those with five to nine years earn £11.0. Mean wages drop slightly, at £10.70, in the range of 10 to 19 years before rising substantially at 20 or more years to £14.90.
The location of the job affects salary, with welders in Minnesota earning the most at a median of £13.80 an hour, followed by Illinois at £13. In California, welders average £10.90, while those in Texas get £11.10, according to PayScale.
Wages vary by employer, with welders under contract receiving the highest wages at a median of £11 per hour. Certified welders working for state and local governments make £10.70, while those in private companies earn £10.70, PayScale reports.
