The technicians of the welding

The welding is a process of union of metals by heat or pressure. Solder requires to guarantee a successful result and sure, thus, has to take: the selection of the process of welding adapted, the preparation of the materials, the election of the material of filler like the gas of protection, the adjust of the parameters of welding, the preparation of the squad and the zone of work, the application of technicians of suitable welding like the inspection and control of quality.

There is distinct technicians of welding according to the types of materials, the function, the cost and the efficiency; being the most common:

Welding by electrical arch: by means of an electrode and the material of base, with the temperature generated by the arch creates the union of both.
Welding by gas (Oxiacetilénica): it uses a llama of gas to melt the materials and join the metals.
Welding by resistance: from a resistance of electrical current generates heat and melt the materials to join.
Welding by points: it is similar to the welding by resistance, but applies only to specific points.

In the following the webs and communities on line can expand the information and find resources, discussions and opportunities of learning:

WeldingWeb: A forum of information and exchange of knowledges on the welding, with experiences and councils for professionals and enthusiastic.
American Welding Society (AWS): A professional organisation with resources, formation, certifications and events related with the welding.
Welding.com: A website with resources, articles and spaces of discussion on the welding.

The professional profile of the soldador varies in function of the type of work as of the industry, but generally includes a combination of technical skills, practical experience and personal qualities. In addition to the certifications and formation, the skills of security, of resolution of problems like the attention to the detail, the effective communication, the work in squad with other professionals and the adaptability to the different surroundings.
