PARTIES TO DISPUTE:

STATEMENT OF CLAIM: Claim of the System Committee of the Brotherhood that:
(1) The carrier violated the Agreement when it assigned Shop Craft employes instead of Bridge and Structures employes to perform welding work in connection with attaching angle iron supports to the top of the tool cage at the Huntington Repair Shop on September 27, 1982 (System File C-TC-1953/MG3696).
(2) Because of the aforesaid violation, B&B Mechanics X. D. Brown, D. E. Scarberry, W. P. Steele, R. E. Adkins, C. Perry, H. B. Hunter, C. R. Stratton, 1. Wiley, H. Caly, W. Smith and C. Hanshaw shall each be allowed pay at their respective rates for an equal proportionate share of the two (2) man-hours expended by Shop Craft employes performing the work referred to in Part (1) hereof.
OPINION OF BOARD: The 11 named Claimants here are ,^embers of the Carrier's
 Bridge and Structures Forces. They assert the welding of prefabricated angle iron supports to the top of the tool cage at the Huntington, West Virginia Repair Shop on September 27, 1982, was improperly assigned to two Boilermakers emploced by the Carrier.
The Organization asserts the disputed assignment violated Rule 66 of the Agreement. The Carrier disagrees. It contends that Boilermakers and other Shop Craft Employes frequently attach racks, reels, brackets and the like to various structures in the Huntington Shop. Such work, it insists, has never been considered exclusively reserved to the Claimants. it points, in support, to Rule 79 of the C & 0 Shop Crafts Agreement.
Under applicable Board rules, the International Brotherhood of Boilermakers-Blacksmiths were notified of the organization's claim of entitlement to the disputed wo Rules Agreement covering Boilermaker Craft Employes. It cites, as did the Carrier, Rule 79. It also asserts a strong past practice supports its right to the disputed work.
Rule 66, while describing the Scope of the work within the Organization's jurisdiction, conta ·...is performed by other employees under other agreements in accordance with the rules of such agreements or past practice in the allocation of such work between the different crafts'.

        Rule 79 of the Boilermakers' Agreement specifies that:


        "Boilermakers' work shall consist of ...


              x e r


        "Boilermakers' work in connection with I-beam, channel iron, angle iron and T-iron work...


              i ~ x


        "Oxy-acetylene, thermit and electric welding on work generally recognized as boilermakers' work.'


On balance, we are obliged to find that the welding of angle iron supports to structures at the Huntington Repair Shop falls within the exception contained in Rule 66. Such work seems clearly to fall within the purview of Rule 79 of the Boilermakers' Agreement.
The Organization, in our judgment, has failed to meet its burden of proof in this case. it has not convincingly established the Claimant's right to the disputed work either under Rule 66 or an exclisive practice. Accordingly, the claim must be d
