Welders, the professionals specialized in joining pieces

marzo 31, 2021
Welders are basically engaged in join parts by applying intense heat in order to obtain a resulting body that is homogeneous and rigid. This work is called welding and is usually done between metals, although thermoplastic materials are also worked.

The main welding methods are: use of electric arc, electrodes protected with inert gas, flux core, ionized inert gas blowing or gas flap, which is what is known as oxyacetylene or oxyhydrogen gas.

Other techniques also used are electric resistance welding, the electric beam, induction, laser beam and aluminothermy. The welders job is complex, since they must select and install manual welding equipment and materials based on specific job specifications sometimes quite complex. A second phase of the work consists of examine and prepare surfaces that must be united, which implies, on certain occasions, the adjustment of valves or very delicate electrical parts.

Specific training

Although a compulsory qualification is not necessary for the development of the profession of welder, there are a number of vocational training training cycles or Occupational training where you can acquire the theoretical and practical knowledge necessary to start a professional career in the welding sector:

Middle Grade Training Cycle in welding and boilermaking

These are studies that enable us to carry out operations related to metal constructions, fixed and mobile, with the necessary security conditions and always within the current security regulations.

The access routes are the ESO, the access tests to training cycles for those over 17 years of age, the CFGM access course for more than 17 years of age or to be in possession of another training cycle of medium degree.

The study plan for this Training Cycle is 2,000 hours plus 400 hours of training in work centers.

If you are from Mexico, this post will provide you with more detailed information.

Occupational training

Another way to learn the trade is through a course in Occupational Professional Training. These courses are aimed at both active people who want to improve their employment situation and those who are unemployed. These are training programs that combine theory with practice, whosepurpose is to improve insertion capacity by specializing or improving specific professional competencies.

The offer of Occupational Training courses is very wide, the following modules being the most convenient to learn the trade of welder:

  • Electric welding.
  • Semi-automatic.
  • Oxyacetylenic.
  • Welder of Metallic Structures.

Professional profile and skills

The main features you should have from a welder are the following:

  • Good physical shape, especially strength in the hands and ability to lift considerable weights, as well as flexibility to enter and work in small spaces.

  • Be thorough and able to follow instructions very technical and precise.
  • Good psychomotor coordination.
  • Ease of follow complex job procedures.
  • high capacity of concentration.
  • Skill in manual work.
  • Communication and work skills in a team even with professionals from other specialties such as craftsmen or sheet metal workers.

In the field of competencies, a professional welder must have extensive knowledge and experience in various techniques, the most representative being:

  • Cutting techniques, curved flame cutting and bending of iron and other metals.
  • Electric and oxyacetylene welding.
  • Correction of deformations due to expansion or contraction.
  • Forging and iron work.
  • Interpretation of plans and drawings.

On the other hand, you must also have additional preparation in:

  • Prevention of occupational hazards and specific health and safety regulations for the construction sector.
  • Knowledge of operation, use and process of maintenance of various toolsnecessary for the development of this profession.

Specific jobs

During the exercise of his profession, a welder will usually have to perform the following tasks:

  • Preparation of everything you need for your work in the workshop or construction site, which may include the assembly and disassembly of scaffolding.
  • Selection and check of welds.
  • Union of metal sheets and other elements.
  • Cleaning, treatment and conservation of welds.
  • Controls quality.
  • Elaboration of budgets.
  • Handling and maintenance of tools, materials, auxiliary means and protections.

Professional perspectives

Welding is a job sector that requires a large number of labor for the construction of both public and civil works. The data indicates that there is an increasing demand for professionals specialized in mechanical manufacturing, such as plumbers and welders.

People with knowledge of welding are very versatile, being able to exercise their professional activity in different areas such as: assembly of boilermaking items and their repair, carpentry and subsectors such as shipbuilding or the manufacture of transport vehicles in the industrial sector.

Also, welders can easily convert to other trades such as: locksmith, forger, tubero or industrial sheet metal worker.
