    Tutorial Question for Week 13

    CA 3703 CONSTRUCTION METHODS & EQUIPMENT

    Question 1

    The following figures are detailed drawings for element welding

    connections, all the dimensions are given in mm:

    (a) State the welding methods in Figures (1) and (2)


    (b)Explain the meaning of the symbol 50-100 in Figure (1)
    (c) Explain the meaning of the symbol 10 and 30 0 in Figure (2)
    (d) Explain the meaning of the symbol "o" in Figure (3)
    (e) What is the effective throat thickness of welding in Figure (4)
    Solutions:

    (a) Figure (1): fillet welds. Figure (2):


    groove welds.

    (b) 50-100 indicates that 50mm long welds


    having a space 100mm between two
    adjoining centers.

    (c) Figure (2) indicates single-v welded


    from one side having 10mm in rooting
    opening and the groove angle is 300, while
    there is a backing bar on another side.

    (d) It means weld all around.

    (e) The effective throat thickness e can be


    e
    determined by: sin45 = 8 , then e=5.6(mm)
    o

    Question 2
    The following figures show the detailed drawings of
    welding connections for steel structural elements; all
    the dimensions are given in units of mm:
    Write out the welding symbols for the field welding
    connection (all the leg lengths are 6mm) shown in the
    following figure.

    The connection can be expressed by the


    following welding symbols:
