FIGURE 21

Vertical-down Welding

Refer to Figure 22 Vertical-down welds are applied at a fast pace. These welds are therefore shallow and narrow and, as such, are excellent for sheet metal. Vertical-down welds may be applied to 5/32” (3.9 mm) and lighter material.

Use stringer beads and tip the gun in the direction of travel so the arc force helps hold the molten metal in the joint. Move as fast as possible consistent with desired bead shape.

The important thing is to continue lowering the entire arm as the weld is made so the angle of the gun does not change. Move the electrode wire fast enough that the slag does not catch up with the arc. Vertical-down welding gives thin, shal- low welds. It should not be used on heavy material where large welds are required.

Soldadura Vertical Descendente

Consulte la Figura 22. Las soldaduras verticales descendentes se aplican rápidamente. Por lo tanto, son estrechas y poco profundas, lo que las hace excelentes para las hojas metálicas. Las soldaduras verticales descendentes pueden aplicarse en materiales de 3.9 mm (5/32”) y más ligeros.

Utilice cordones extendidos e incline la punta de la antorcha en dirección de la trayectoria, para que la fuerza del arco ayude a mantener el metal fundido en la unión. Mueva lo más rápido posible y en forma congruente con la soldadura deseada.

Lo importante es seguir moviendo todo el brazo conforme se realiza la soldadura, para que el ángulo de la antorcha no cam- bie. Mueva el alambre tubular lo suficientemente rápido para que la escoria no haga contacto con el arco. La soldadura ver- tical descendente da como resultado soldaduras delgadas y uniformes. No deberá utilizarse este tipo de soldadura en materiales pesados, donde se requieren soldaduras mayores.

Soudage à la verticale en descendant

Voir la figure 22. On effectue les soudures à la verticale en descendant à un rythme rapide. Par conséquent ces soudures sont peu profondes et étroites et donc excellentes pour les tôles. Les soudures verticales en descendant peuvent être effectuées sur les tôles de 5/32 po (3,9 mm) et moins.

Effectuer des cordons étroits et pointer le pistolet dans le sens du déplacement de sorte que la force de l'arc permette de maintenir le métal fondu dans le joint. Déplacer le pistolet le plus rapidement possible selon la forme du cordon que l'on désire obtenir.

Il est important de continuer à baisser le bras lors de la réalisa- tion de la soudure de sorte que l'angle du pistolet ne change pas. Déplacer le fil-électrode suffisamment vite pour que le laitier ne rattrape pas l'arc. Le soudage à la verticale en descendant donne des soudures minces et peu profondes. On ne doit pas l'effectuer sur du métal épais qui nécessite des soudures larges.
