LEARNING TO WELD

APRENDIENDO A SOLDAR

APPRENTISSAGE DU SOUDAGE

When comparing the GMAW and FCAW processes, you can see that the principal difference between the two lies in the type of shielding used. GMAW uses gas for shielding, thus we have Gas Metal Arc Welding. FCAW uses the melting or burning of the core ingredients for shielding, and is thus termed Self-Shielded Flux Cored Arc Welding.

Al comparar los procesos GMAW y FCAW puede observarse que la diferencia principal entre los mismos es el tipo de pro- tección que se utiliza. El proceso GMAW utiliza el gas como protección, por lo que se origina una Soldadura de Arco Metálico con Gas. El proceso FCAW utiliza la fundición y el quemado de los ingredientes tubulares como protección, y es por eso que se obtiene una Soldadura de Arco Tubular Autorevestido.

Si l'on compare les procédés GMAW et FCAW, on peut con- stater que la différence principale entre eux réside dans le type de protection utilisé. Le procédé GMAW utilise un gaz protecteur d'où le nom de soudage à l'arc sous gaz avec fil plein. Le procédé FCAW utilise la fusion des ingrédients de l'âme du fil (fourré) pour la protection d'où son nom de soudage à l'arc avec fil fourré.

The recommended wire for Gas Metal Arc Welding (MIG) is Lincolnweld 0.025” (0.6 mm) L-56 electrode. Lincolnweld” L- 56 is capable of welding a wide range of mild steels in all positions, however, more skill is required for out-of-position welding with the GMAW process.

PROCESS SELECTION

By gaining knowledge of the differences between the two processes, you will be able to select the best process for the job you have at hand. In selecting a process, you should con- sider:

For GMAW (MIG) Process

1.Is most of my welding performed on 16 gauge and lighter materials?

2.Can I afford the extra expense, space, and lack of porta- bility required for gas cylinders and gas supply?

3.Do I require clean, finished-looking welds?

If you have answered yes to all the above questions GMAW may be the process for you. If you have answered no to any of the above questions, then you should consider using the FCAW process.

Para la Soldadura de Arco Metálico con Gas (MIG) se recomienda el electrodo Lincolnweld L-56 de 0.6 mm (0.025”). El Lincolnweld L-56 es capaz de soldar una amplia gama de aceros dúctiles en todas las posiciones; sin embar- go, con el proceso GMAW se requiere mayor habilidad para la soldadura fuera de posición.

SELECCIÓN DEL PROCESO

Al aprender más sobre las diferencias existentes entre los dos procesos, usted podrá elegir el mejor para el trabajo que va a realizar. Al seleccionar el proceso, deberá considerar lo siguiente:

Para el Proceso GMAW (MIG)

1.¿La mayoría de mi trabajo de soldadura se realiza con calibre 16 y materiales más ligeros?

2.¿Puedo afrontar los gastos, el espacio adicional y la falta de portabilidad de los cilindros y del suministro de gas?

3.¿Necesito soldaduras limpias y con buen acabado?

Si usted ha contestado sí a todas las preguntas anteriores, el proceso que le conviene es el GMAW. Si usted ha con- testado no a alguna de las preguntas anteriores, entonces usted deberá considerar utilizar el proceso FCAW.

Le fil recommandé pour le soudage à l'arc sous gaz avec fil plein (MIG) est le fil L-56 de Lincoln de 0,025 po (0,6 mm). Ce fil est capable de souder tout un éventail d'aciers doux en toutes positions, mais des compétences supplémentaires sont nécessaires pour le soudage hors position avec le procédé GMAW.

CHOIX DU PROCÉDÉ

En acquérant des connaissances sur les différences entre les deux procédés, vous serez capable de choisir le meilleur procédé pour le travail que vous avez à effectuer. Quand on choisit un procédé on doit prendre en compte les éléments suivants :

Dans le cas du procédé GMAW (MIG)

1.Est-ce que j'effectue la plupart des travaux de soudage sur des matériaux de 16 d'épaisseur et plus minces?

2.Puis-je me permettre les dépenses supplémentaires et l'encombrement des bouteilles de gaz et des sources de gaz?

3.Dois-je effectuer des soudures nettes et présentant un bel aspect?

Si vous avez répondu oui à toutes les questions ci-avant, le procédé GMAW peut s'adresser à vous. Si vous avez répondu non à une des questions ci-avant, alors vous devriez envisager d'utiliser le procédé FCAW.
