Title (EN) MULTI-ARM WELD GUN
(FR) PISTOLET DE SOUDAGE A BRAS MULTIPLES
Abstract:
(EN) A multiple arm welding gun includes at least two weld gun arms (11, 13) where one arm retracts away from mating work pieces while at least one other arm remains operational, thus allowing a multiple arm weld gun to act as a single arm weld gun. Once one or more weld gun arms is retracted, the remaining weld gun arms may be repositioned with respect to the work pieces in a space not previously accessible to the multiple arm weld gun before retraction of an arm.
(FR) Le pistolet de soudage à bras multiples comprend au moins deux bras (11, 13), dont un se rétracte en s'éloignant des pièces à usiner correspondantes, tandis qu'au moins un autre bras reste opérationnel, ce qui permet au pistolet de soudage à bras multiples de fonctionner comme un pistolet de soudage à bras unique. Une fois qu'au moins un des bras dudit pistolet est rétracté, les bras restants peuvent être repositionnés par rapport aux pièces à usiner dans un espace qui n'était pas, avant la rétraction d'un bras, accessible au pistolet de soudage à bras multiples.
