LEARNING TO WELD

Butt Welds

Place two plates side by side, leaving a space approximate- ly one half the thickness of the metal between them in order to get deeper penetration.

Securely clamp or tack weld the plates at both ends, other- wise the heat will cause the plates to move apart. See Figure 17.

Now weld the two plates together. Weld from left to right (if right handed). Point the wire electrode down in the crack between the two plates, keeping the gun slightly tilted in the direction of travel. Watch the molten metal to be sure it dis- tributes itself evenly on both edges and in between the plates. This is referred to as the “pull technique”. On thin gauge sheet metal, use the “push technique”. See “Welding Techniques for GMAW (MIG) Process”.

APRENDIENDO A SOLDAR

Soldadura a Tope

Coloque las dos placas una al lado de la otra, dejando un espacio de aproximadamente la mitad del ancho del metal entre ellas, con el fin de obtener una penetración más pro- funda.

Asegure las placas en ambos extremos con una pinza o con un punto de soldadura, ya que de otra manera el calor haría que las placas se separaran. (Vea la Figura 17).

Ahora, suelde las dos placas. Trabaje de izquierda a derecha (si es diestro). Coloque el electrodo tubular sobre la abertura entre las dos placas, manteniendo la antorcha lig- eramente inclinada en dirección de la trayectoria. Observe el metal fundido para asegurarse de que se distribuya equi- tativamente en ambos bordes y entre las placas. A esto se le conoce como “técnica de arrastre”. En hojas de metal del- gadas utilice la “técnica de empuje”. Vea “Técnicas de Soldadura para el Proceso GMAW (MIG)”.

APPRENTISSAGE DU SOUDAGE

Soudures bout à bout

Placer deux tôles côte à côte, en laissant entre-elles un écartement égal à environ la moitié de l'épaisseur du métal pour obtenir une plus forte pénétration.

Bien immobiliser les tôles au moyen de clames ou de soudures de pointage aux deux extrémités, pour ne pas que la chaleur sépare les deux tôles. Voir la figure 17.

Souder maintenant les deux tôles. Souder de gauche à droite (pour un droitier). Pointer le fil-électrode dans l'écarte- ment entre les deux pièces, en inclinant légèrement le pisto- let dans le sens du déplacement. Observer le métal fondu pour s'assurer qu'il se repartit de façon régulière sur les deux bords et entre les tôles. C'est ce que l'on appelle générale- ment la technique “en tirant”. Sur des tôles minces utiliser la technique “en poussant”. Voir “Techniques de soudage pour le procédé GMAW (MIG)”.

FIGURE 17

Penetration

Unless a weld penetrates close to 100% of the metal thick- ness, a butt weld will be weaker than the material welded together. In the example shown in Figure 18, the total weld is only half the thickness of the material thus the weld is only approximately half as strong as the metal.

FIGURE 18

FIGURE 19

In the example shown in Figure 19, the joint has been weld- ed so that 100% penetration could be achieved. The weld, if properly made, is as strong as or stronger than the original metal.

FIGURA 17

Penetración

Si la soldadura no penetra casi el 100% del grosor del metal, entonces una soldadura a tope será más débil que el mate- rial soldado. En el ejemplo que se muestra en la Figura 18, la soldadura total penetró sólo la mitad del grosor del mate- rial, por lo que será aproximadamente la mitad de resistente que el metal.

FIGURA 18

FIGURA 19

En el ejemplo que se muestra en la Figura 19, la unión ha sido soldada para que pueda obtenerse un 100% de pene- tración. Si la soldadura se realiza adecuadamente, entonces será tan resistente como el metal original.

FIGURE 17

Pénétration

Si la pénétration n'est pas de 100 % ou presque, une soudure bout à bout est plus faible que les pièces soudées. Dans l'exemple donné à la figure 18, la soudure totale ne fait que la moitié de l'épaisseur du métal. Par conséquent, la soudure est environ deux fois moins résistante que le métal.

FIGURE 18

FIGURE 19

Dans l'exemple donné à la figure 19, l'assemblage a été soudé de façon à pouvoir obtenir une pénétration de 100 %. La soudure, si elle est bien réalisée, est aussi résistante sinon plus que le métal de base.
