WELDING TECHNIQUE [8 records]

Record 1 2017-01-25

English

Subject field(s)
  • Welding - Various Processes
DEF

A welding technique in which the arc force or gun is directed opposite to the progress of welding.

OBS

The term backhand technique is sometimes referred to as the "pull gun technique" in GMAW(gas metal arc welding) and in FCAW(flux-cored arc welding).

OBS

In this method, the torch precedes the welding rod, ... the torch is held at approximately a 45 degree angle from the vertical away from the direction of welding, with the flame directed at the molten puddle. The welding rod is between the flame and the molten puddle. This position requires less transverse motion than is used in forehand welding.

OBS

backhand welding; pull gun technique : terms standardized by the American Welding Society(AWS).

OBS

backhand welding: term officially approved by the Lexicon Project Committee (New Brunswick).

French

Domaine(s)
  • Procédés de soudage divers
CONT

Soudage à droite. Cette méthode s'applique au soudage de tôles plus épaisses [...] et chanfreinées. Le chalumeau est toujours animé d'un mouvement rectiligne mais la baguette reste plongée dans le bain tout en étant animée d'un mouvement de va-et-vient d'un bord à l'autre.

OBS

soudage en arrière; soudage à droite : termes uniformisés par le Comité du projet de lexiques (Nouveau-Brunswick).

Subject field(s)
  • Welding - Various Processes
DEF

A welding technique in which the welding torch or gun is directed toward the progress of welding.

OBS

forehand welding: term standardized by the American Welding Society (AWS).

OBS

forehand welding: term officially approved by the Lexicon Project Committee (New Brunswick).

French

Domaine(s)
  • Procédés de soudage divers
CONT

Soudage à gauche. Le chalumeau progresse régulièrement sans déplacements latéraux. La baguette est plongée à intervalles réguliers dans le bain. On ne peut souder ainsi à plat que des tôles dont l'épaisseur ne dépasse pas 4 mm, sinon le métal fondu, trop abondant, s'effondre par gravité. On peut remédier à cet inconvénient en plaçant à l'aide d'un support, les tôles en position oblique; le mouvement se faisant suivant le remontée, la pesanteur fait alors glisser le métal fondu sur le point de soudure précédent ce qui le renforce. Pour des épaisseurs supérieures à 10 mm, on soude en deux passes successives.

OBS

soudage à gauche; soudage en avant : termes uniformisés par le Comité du projet de lexiques (Nouveau-Brunswick).

Record 4 2002-07-31

English

Subject field(s)
  • Arc Welding
DEF

A welding technique in which concentrated heat penetrates the work piece leaving a hole at the leading edge of the weld. As the heat source moves on molten metal fills the hole forming a weld bead.

French

Domaine(s)
  • Soudage à l'arc
DEF

Technique de soudage tirant parti de la puissance de pénétration de l'arc qui traverse la pièce à souder et forme un trou sur le bord avancé de la soudure. A mesure que la torche se déplace le long du joint, le métal coule vers l'arrière et referme le trou pour constituer le cordon.

Record 5 2002-07-31

English

Subject field(s)
  • Welding - Various Processes
CONT

The conventional method for starting such a weld was to drill a pilot hole to serve as the initial keyhole, carefully align the welding torch over the pilot hole, adjust the standoff distance, and then turn on the torch at full power.... The new starting technique does not depend on precise manual alignment. The welding torch is positioned with no more than the usual care. As the torch begins to move along the weld, the welding current is gradually increased toward the full operating level, causing the depth of the weld to increase gradually until the keyhole is formed.... The standoff is controlled by the automatic-voltage-control portion of the welding equipment. At the end of a circumferential weld, the torch can continue a short distance past the starting point to overlap and thereby complete the weld in the starting transition region.

Subject field(s)
  • Concrete Facilities and Equipment
  • Facilities and Equipment (Metal Joining)
CONT

Self-Shielded Flux Cored Welding. 1. Use a drag(pull) gun technique. 2. Keep the wire clean and dry for best weld results. 3. The weld is similar to Stick welding, in that a layer of slag must be removed from the weld after welding. Use a chipping hammer and a wire brush.

CONT

After several months, residual concrete inside the truck mixer drum hardens into a thick layer. This concrete must be removed periodically. Workers - drivers, laborers, or contract workers - enter the drum and use a pneumatic chipping hammer to break up the hardened concrete.
