Welding module issue?

I have this weld module that should , when triggered, descend through the children of the character, check if they are a part or union, then checking for the value "BodyPartType" In each part and if the value = "Core" Then weld the appropriate parts to the aforementioned body part. However, for some reason it only gets to the right elbow and stops.

Any help is appreciated.

function weld(p1,p2,c0)
    local w = Instance.new("Weld",p1)
    w.Part0 = p1
    w.Part1 = p2
    w.C0 = c0 or p1.CFrame:inverse() * p2.CFrame
    return w
end

function PerformWeld(player)
local DataLoad = player.Character:WaitForChild("PlayerData")    
    local PlayerAttire = DataLoad:FindFirstChild("AttireData")
    local WD = DataLoad.WeldingAids:FindFirstChild("WeldData")
    local Weldee = DataLoad.WeldingAids.Weldee
local PE = player.Character:FindFirstChild("PlayerEquipment")

local Outfit = game.ServerStorage:FindFirstChild(Weldee.Value):Clone()
    local char = player.Character or player.CharacterAdded:wait()
    local Garment = Outfit:WaitForChild(WD.Value.."Components")
    local CurrentSection = Garment:Clone()
    CurrentSection.Parent = char

    for _,v in pairs(CurrentSection:GetChildren()) do
        if v.ClassName == "Part" or v.ClassName == "UnionOperation" then
            v.Anchored = true

        end
    end

    CurrentSection.Parent = PE

    for _,v in pairs(CurrentSection:GetChildren()) do
        if v.ClassName == "Part" or v.ClassName == "UnionOperation" then
            if v ~= CurrentSection["ArmorCore"] then
                weld(v, CurrentSection["ArmorCore"])
            end
        end
    end

    local CurrentSectionWeld = weld(CurrentSection["ArmorCore"], char[WD.Value], CFrame.new())

    for _,v in pairs(CurrentSection:GetChildren()) do
        if v.ClassName == "Part" or v.ClassName == "UnionOperation" then
            v.Anchored = false
            v.CanCollide = false

            print ("Welded "..WD.Value)
        end
    end
end




local WeldModule = {}

function WeldModule.CycleWeld(player)
    print("Module_Booted")                                                                                                    
local DataLoad = player.Character:WaitForChild("PlayerData")    
local WD = DataLoad.WeldingAids:FindFirstChild("WeldData")
    local C = player.Character
    --local children = C:GetChildren()
            print("Data_Established"..player.Name)
            for _,v in pairs(C:GetChildren()) do    
    if v.ClassName == "Part" or v.ClassName == "UnionOperation" then
    if v:FindFirstChild("BodyPartType").Value == ("Core") then
            WD.Value = v.Name
                print("Weld_Booted")
                PerformWeld(player)
                print("Welded")
            wait(0.2)   

    else print("nil")

    end
    end

end
end

return WeldModule
