A '''boilermaker''' is a [[Tradesman|tradesperson]] who [[Metal fabrication|fabricates]] steels, iron, or copper into boilers and other large containers intended to hold hot gas or liquid, as well as maintains and repairs boilers and boiler systems.<ref name=":0">Bureau of Labor Statistics, US Department of Labor, Occupational Outlook Handbook, 2014-15 Edition, Boilermakers, on the Internet at http://www.bls.gov/ooh/construction-and-extraction/boilermakers.htm (visited January 23, 2014)</ref>

Although the name originated from craftsmen who made [[boiler]]s, boilermakers assemble, maintain, and repair other large vessels and closed vats, in addition to boilers.

The boilermaker trade evolved from industrial [[Blacksmith|blacksmithing]]; in the early nineteenth century, a boilermaker was called a ''[[boilersmith]]''. The involvement of boilermakers in the [[shipbuilding]] and engineering industries came about because of the changeover from wood to iron as a construction material. It was often easier, and less expensive, to hire a boilermaker who was already in the shipyard{{mdash}}fabricating iron boilers for wooden steamships{{mdash}}to build a ship. This overlap of skills could extend to anything large and made of iron{{mdash}}or later, steel. In the UK, this effective monopoly over an important skill of the industrial revolution led to boilermakers being labeled "the labour aristocracy" by historians.<ref>{{Cite book|title = The Tide of Democracy: Shipyard Workers and Social Relations in Britain, 1870-1950|url = https://books.google.com/books?id=n4zLCgAAQBAJ|publisher = Oxford University Press|date = 2010-05-25|isbn = 9781847793386|language = en|first = Alastair J.|last = Reid}}</ref>

==Application==
Boilermaking, [[welding]], and fitting tubes can be a full-time requirement at [[Power station|power plants]]. Stress fractures, leaks, and corrosion demand continual repair or replacement resulting from operation at very high steam pressures. Other boilermakers might work seasonally or on an individual project such as re-fitting a boiler in a seagoing vessel or remodeling a steam plant.

Boiler repair can be a high-value, high-cost service since even the smallest steam boilers for [[Dry cleaning|dry cleaners]] and [[Tailor|tailors]] can cost upwards of $20,000 to replace.{{Citation needed|date=August 2019}}

===Domestic boilers in the United States of America===
In the United States, many boilermakers are employed in repairing, [[repiping]], and re-tubing commercial steam and [[Boiler (power generation)|hot water boilers]] used for heating and domestic hot water in commercial buildings and multi-family dwellings.<ref name=":0" /> Sometimes these boilers are referred to as [[pressure vessel]]s. Generally, a pressure vessel is a storage tank or vessel that has been designed to operate at pressures above {{convert|15|psi|bar kPa|sigfig=3|abbr=on}}.

The two main responsibilities of boilermakers are the use of [[oxy-acetylene]] gas torch sets to cut or gouge steel plate and tubes, followed by [[gas tungsten arc welding]] (GTAW), [[shielded metal arc welding]] (SMAW), or [[gas metal arc welding]] (GMAW) to attach and mend the cut sections of tubes and steel plates.<ref name=":0" />

==Training and certification in the United States==
Boilermakers usually go through a formal [[apprenticeship]] which includes about four years of paid on-the-job training combined with classroom instruction. Unions and many employers offer these apprenticeships. To become an apprentice, one must be at least 18 years old and have a high school diploma or GED. Attending a trade or technical school combined with employer-provided training can accelerate the learning curve.<ref>Employment and Training Administration, US Department of Labor, O*NET Online, Boilermakers, on the Internet at http://online.onetcenter.org/link/details/47-2011.00 (visited January 23, 2014)</ref>

According to U. S. Census Bureau data of 2012, boilermakers are the most male "saturated" job in the USA, having a share of 99.8 % males and 0.2 % females.<ref>[https://imgur.com/gallery/YwDuP7P Work Gender Distribution - UNITED STATES]</ref>

===R Stamp Welding===
Boiler repair in the United States is governed by the [[National Board of Boiler and Pressure Vessel Inspectors]] and the [[ASME|American Society of Mechanical Engineers (ASME)]] under a classification called R Stamp Welding. In order to perform R Stamp welds and repairs, boilermakers are tested and certified in the quality of their weld joints through a rigorous testing procedure. R stamps are issued to companies that have existing ASME code stamps issued for construction and whose quality control system covers repairs or follow the guidelines set up by ASME to obtain an R stamp. Welders identify their welds by stamping their identifying welder number adjacent to their completed weld with a set of steel stencils.<ref>{{Cite web|url=https://www.nationalboard.org/index.aspx?pageID=115&ID=160|title=R Stamp|website=The National Board of Boiler and Pressure Vessel Inspectors|access-date=2019-08-11}}</ref>

===Power Piping===
Welding, fitting, and installing the tubes and accessories that attach to the boiler can also be performed by boilermakers, and is governed by the same organizations as R Stamp Welding. This certification is called Power Piping and is governed by ASME Code section B31.1.<ref>{{cite web|url=https://www.asme.org/codes-standards/find-codes-standards/b31-1-power-piping|title=ASME B31.1 Power Piping|website=ASME|access-date=2019-08-10}}</ref>

==Trade unions==
===United States and Canada===
The [[International Brotherhood of Boilermakers, Iron Ship Builders, Blacksmiths, Forgers and Helpers]] is a [[trade union|labor union]] for boilermakers in Canada and the United States.

===UK===
In the UK, boilermakers traditionally joined the [[Amalgamated Society of Boilermakers, Shipwrights, Blacksmiths and Structural Workers|Boilermakers Society]] which merged with the [[GMB (trade union)|General and Municipal Workers' Union (GMWU)]], then an unskilled union, to form the modern [[GMB (trade union)|GMB]] which still maintains a "craft section" largely for boilermakers.
