☛ Connect steel columns, beams, and girders
☛ Reinforce concrete with welded wire fabrics
☛ Position steel or iron structures with connecting bars and spud wrenches
☛ Check the alignment using plumb bobs, levels, and laser equipment
☛ Fasten bars together with wire
☛ Drill holes into steel for bolts
☛ According to assembly instructions number the steel structures
☛ Hoist steel into the framework

2. Tell me what is blue print reading?
Blueprint reading is like a structural map that covers the steel structure. It is a detail drawing of steel structure, and it carries a label or piece mark to differentiate one steel bar or structure from others. Each piece or segment of steel structure has a single blueprint with detailed information before it become the part of the whole. It carries information even small as hole sizes, dimension, etc.
3. Explain me on what three factors does rigging process depends on?
Rigging process depends on three factors
☛ Capacity of the hoisting device
☛ Working loads of ropes and hardware
☛ Weight of the load to be lifted
6. Tell me if welder made test by 2'' dia, what is his range qualified?
He has qualified 1''-dia and above.
7. Tell me how much percentage is allowed more than test pressure in Pressure relief device?
Test pressure plus10% (10% should be lesser than 50Psi).
PQR stands for procedure qualification record. The PQR documents what occurred during welding the test coupon and the results of testing of the coupon.
